General Information 1. CTC EcoZenith i550 Pro design This chapter illustrates the main components and describes the subsystems which, in different configurations, form part of the main system. For more information about the EcoZenith configurations, refer to the “Pipe connections” chapter. 1.1 Main components Bivalent Mixing Valve The automated mixing valve ensures that an even heat is continuously supplied to the radiator system.
General Information 2. CTC EcoZenith i550 Pro function The CTC EcoZenith i550 Pro is a multi-tank with almost unlimited possibilities. ! The EcoZenith is intended for houses and properties with water-borne heat. The multi-tank features include intelligent control, a water volume of 540 litres, bivalent mixing valve, two hot water coils, a solar coil and two 9 kW immersion heaters giving a total of 18 kW.
General Information 2.1 Heating System The EcoZenith is equipped with a bivalent mixing valve, which always delivers an even temperature, without variation, to the heating system. The bivalent mixing valve is controlled by an outdoor sensor and, optionally, by a room sensor. When operating with outdoor sensor alone, the desired curve inclination and adjustment are set. These values differ from home to home and should be adjusted to suit your needs.
General Information 2.2 DHW The final heating of the hot water takes place in the upper tank. It also acts as additional heating for the heating system when the lower tank is not sufficient. The hot water is heated using two finned copper tube coils of approx. 40 metres connected in parallel. The coils preheat the water in the lower tank and the water reaches maximum temperature in the upper tank. The low inner volume and high rate of water turnover in the copper coil prevents build-up of bacteria.
General Information 2.3 Heat pump The EcoZenith is designed with two parts in order to ensure the heat pump operates to maximum possible economy. The heat pump is connected via two diverting valves to the EcoZenith and ensures that the heat is directed into the upper and lower tanks, respectively. For instance, when the heat pump pumps towards the upper tank, the diverting valves send the flow to the two uppermost connections, so that the flow enters port 1 and exits through port 2.
General Information 2.3.2 Lower tank In the lower tank the heat pump operates to provide heat to the heating system. Heat pump operation is of so-called floating condensation type. However, the lower tank never drops below the set lowest temperature. Floating condensation operation is where the heat pump heats to the temperature required by the heating system.
General Information 2.3.3 More Than One Heat Pump. If more than one heat pump is installed, heat pumps two and three are connected to the lower tank only. Only one of the heat pumps alternates between DHW and heating operation. The Ecozenith’s controller equalises the operating time between the heat pumps so as to maximise heat output and minimise the load on them.
General Information 2.3.5 Speed-controlled charge pump (accessory from CTC) Each heat pump should be provided with a separate charge pump that is controlled in tandem with its respective heat pump. If a speed-controlled PVM charge pump (accessory from CTC) is connected to the heat pump and controlled from the EcoZenith, the flow will be automatically set without any adjustment needed via the control valve.
General Information 2.5 Additional boiler (pellets, oil, gas, electricity) The EcoZenith can control an external additional boiler (pellets, oil, gas, electricity). The additional boiler is connected to the upper tank. Use the menu to select whether the external additional boiler should have high or low priority. If high priority is selected, the external additional boiler is activated before the immersion heater(s); when low priority is selected, the immersion heater(s) is/are activated first.
General Information 2.6 Solar Energy The EcoZenith contains a 10 m long 18 mm finned and internally grooved solar coil which manages approx. 10 m² of solar panel. On larger solar panel installations, the solar energy is connected via an external heat exchanger (see figure 2). The heat exchanger is connected to the upper and lower connections on the lower part of the CTC EcoZenith (either side is possible).
General Information 2.7 Recharging Bedrock/Ground If a liquid-water heat pump is connected, a diverting valve can be installed on the solar circuit and connected to the brine circuit (the loop in the bore hole or the ground heat loop) to charge the bedrock/ground when the EcoZenith is fully charged (factory set 85°C). The solar panel temperature should be factory set at 60°C warmer than the brine temperature in order for charging to start.
General Information 2.8 External Hot Water Tank An external water heater can be connected to the EcoZenith. This results in a greater stored hot water volume, which contributes to higher hot water capacity. The incoming cold water first passes through the EcoZenith where it is heated before it flows into the hot water tank and out to the property’s taps. This means that, when the temperature from the EcoZenith is no longer sufficient, the entire volume of the hot water tank is still there to be used.
General Information 2.10 External Buffer Tank The EcoZenith can be connected to one or more buffer tanks. This is mainly used when connecting wood and solar energy systems where the volume in the EcoZenith is not sufficient. Via the accessory “Charging External Storage Tank”, warm water can be sent both from the lower tank to the buffer tank(s) and from the buffer tank(s) back to the EcoZenith. In other words, both charging and recharging of the energy are possible.
General Information 2.10.2 Wood Operation Control The wood boiler charges the EcoZenith until the sensor of the lower tank reaches the factory-set 80°C, before the charge pump starts up and transfers hot water from the lower tank into the top of the first buffer tank. Charging continues until the sensor in the lower tank has fallen 3 degrees (transfer starts at 80 degrees and stops at 77 degrees).
General Information 2.11 Cooling CTC EcoComfort CTC EcoComfort is an accessory which utilises the cool temperatures of the bore hole to create a cool indoor climate in summer. The extent to which you can cool a property depends on several factors, such as the rock temperature available for the case in point, the size of the house, the capacity of the fan convectors, the living area layout, etc. G40 NOTE: Remember to insulate pipes and connections against condensation.
General Information 3. The House Heating Curve Your home's heating installation The House Heating Curve The heating curve is the central part of the product’s control system. It is the heating curve which determines the compensated flow temperature requirements for your property dependent upon the outdoor temperatures. It is important that the heating curve is correctly adjusted, so that you achieve the best operation and economy possible.
General Information Adjusting the heating curve The method described below can be used to adjust the heating curve correctly. Adjustment if it is too cold indoors • If the outdoor temperature is lower than 0 degrees: Increase the Inclination value by a couple of degrees. Wait 24 hours to see if any further adjustment is required. • If the outdoor temperature is higher than 0 degrees: Increase the Adjustment value by a couple of degrees. Wait 24 hours to see if any further adjustment is required.
General Information Examples of Heating Curves You can see in the diagram below how the heating curve changes with different Inclination settings. The gradient of the curve shows the temperatures that the radiators require at different outdoor temperatures. Primary Flow Temperature Curve Inclination The inclination value which is set is the primary flow temperature when the outside temperature is –15 °C.
General Information 4. DHW The CTC EcoZenith i550 Pro has a total of approx. 40 m finned copper coils for the heating of hot water. These coils preheat the water in the lower tank and the water then runs through the upper tank for the final temperature increase. These two coils running parallel through the EcoZenith allow high flows with low pressure differential, creating excellent conditions for good hot water capacity and comfort.
General Information For higher hot water demands, it can be more economical to set a higher temperature in the lower tank instead of exceeding the temperature limit for the heat pump in the upper tank. However, this is less beneficial to heat pump operation for the radiator requirement because of the higher operating temperature. Furthermore, where solar panels have been installed, some of the solar energy will not be exchanged in the lower tank.

For the property owner 10. Operation and Maintenance Once your new EcoZenith has been installed, you and your installer should together check that the system is in perfect operating condition. Let the installer show you where the switches, controls, fuses etc. are, so that you know how the system works and how it should be maintained. Bleed the radiators after around three days of operation and top up with water if required.
For the property owner Room Sensor A room sensor, which should always be fitted (up to three room sensors can be connected), ensures that the temperature in the room is always suitable and stable. For the sensor to provide the correct signals to the control unit, radiator thermostats should always be fully open in the area where the room sensor is located. When adjusting the system, always do so with all radiator thermostats fully open.
For the property owner 11. Troubleshooting/measures The CTC EcoZenith i550 Pro is designed to provide reliable operation and high levels of comfort, as well as have a long service life. Various tips are given below which may be helpful and guide you in the event of an operational malfunction. If a fault occurs, you should always contact the installer who installed your unit.
For the property owner Current Monitor (protection for main fuses) The CTC EcoZenith i550 Pro has a built-in current monitor. If the system is installed with current sensors (included), there is constant monitoring to prevent overload of the main fuses of the house. If this should happen, electric stages are disconnected from the EcoZenith.
For the property owner 11.1 Information messages Information messages are displayed when appropriate and are intended to inform users about various operational situations. Start delay Start delay The compressor is not allowed to start too quickly when it has stopped. The delay is usually at least 10 minutes. Heating off, radiator sys Shows for each heating system that the product is operating in summer mode when only hot water is required, not heating. Ripple control Shows that ripple control is active.
For the property owner 11.2 Alarm messages Alarm: Wrong phase order compressor Reset alarm If a fault occurs with a sensor, for instance, an alarm is triggered. A message appears on the display informing about the fault. You reset the alarm by pressing the “Reset alarm” button on the display. If several alarms are triggered, they are displayed one after the other. An outstanding fault cannot be reset without being rectified first. Some alarms are reset automatically if the fault disappears.
For the property owner Alarm Text Description Low brine temp Incoming brine temperatures from borehole/ground loop are too low. Press reset and check whether the alarm recurs. If the fault recurs, contact your installer to check the dimensions of the cold side. Low brine flow Low brine flow is very often due to air in the collector system, particularly just after installation. Collectors which are too long can also be a cause. Check also that the brine pump is set to the correct speed.

For the installer 13.3.1 CTC EcoZenith i550 Pro - Radiator system The CTC EcoZenith i550 Pro can be connected to three different radiator systems (heating circuits) with separate room sensors. Mixing valve (Y1) is the main mixing valve and feeds radiator system 1. Mixing valves (Y2) and (Y3) for radiator systems 2 and 3 are sub-mixers. This means that mixing valve (Y1) controls the maximum temperature to mixers (Y2) and (Y3).
For the installer 13.3.2 CTC EcoZenith i550 Pro - Heat pump Heat pump 1 is connected to diverting valves for changing between the upper and lower tanks. Heat pumps 2 and 3 are connected directly to the lower tank for supplying radiators. Ensure that the ports on the diverting valves (Y21) are set as in the schematic diagram. The ports ● must always be connected to heat pump 1. If it is necessary to swap ports (■ and ▲), two jumpers in the actuator must be reconnected.
For the installer 13.3.3 CTC EcoZenith i550 Pro - Solar energy Solar panels (17) can be connected directly to the EcoZenith’s inbuilt solar coil (11). The solar coil is the finned type. The fluid is pumped from the coil by a speed controlled solar pump (G30). In a larger system with several panels of more than about 10m², the panels are connected to an intermediate heat exchanger (05) and the changing solar energy is pumped to the EcoZenith’s lower tank by a speed controlled pump (G32).
For the installer 13.3.4 CTC EcoZenith i550 Pro - Domestic hot water Figure 1 Shows how domestic hot water circulation can be connected to the EcoZenith. The domestic hot water is circulated by pump (G40). New domestic hot water from the finned coil is mixed in by the mixing valve (32), and cooled water is released down to the coil for reheating. Only a part of one coil in the upper tank is used for circulation.
For the installer 13.3.5 CTC EcoZenith i550 Pro - Wood boiler The upper and lower connections are used for connecting a wood boiler to the EcoZenith. This means that the flow from the wood boiler passes through the entire EcoZenith. The flue gas sensor (B8) signals to the EcoZenith’s control system that the wood is burning. Charging from the wood boiler is controlled from the EcoZenith via a charge pump or by external charge equipment, such as Laddomat 21.
For the installer 13.3.6 CTC EcoZenith i550 Pro - Storage tanks (buffer tanks) One or more storage tanks can be connected to increase the water volume; this is done most commonly in connection with wood or solar energy operation. The 3-way valve (Y40) is connected to the upper connection from both the EcoZenith’s upper and lower tanks and then to the top of the first storage tank. Ensure that the ports on the diverting valve (Y40) are set as in the schematic diagram.
For the installer 13.3.7 CTC EcoZenith i550 Pro - External boiler An external boiler (oil, pellets, electric or gas) is connected to the EcoZenith’s upper tank connections. Circulation is undertaken by the pump (G44), which is controlled by the EcoZenith. The sensor (B17) senses the temperature in the external boiler. See also External Boiler Menu in the Detail Description Menus chapter (Installer/Settings/Ext boiler).
For the installer 13.3.8 CTC EcoZenith i550 Pro - Pool A pool is connected to the EcoZenith’s lower tank. This means that the pool is heated by the same energy source as the radiator system prioritises, for example, heat pump or solar panel. One pump (G50/G51, at the top of the drawing) circulates radiator water from the upper connection on the EcoZenith’s lower tank (02) to the pool heat exchanger (14), on to the radiator system’s return pipe and back to the EcoZenith’s lower tank.
For the installer 13.3.9 EcoZenith - CTC EcoComfort (Cooling) CTC EcoComfort is an accessory which utilises the cool temperatures of the bore hole to create a cool indoor climate in summer. By connecting EcoComfort to separate fan convectors, its water is cooled using the bedrock’s cooler collector water. The heat in the house is supplied to the bore hole in the bedrock. CTC EcoComfort comes supplied pre-connected from the factory and is easy to connect to the system.
