Installation (for installers only) 3.2 Disposal B Dispose of packaging in an environmentally responsible manner. B When replacing components, dispose of the old parts in an environmentally responsible manner. 3.3 Electrical connections B BUS connection from the controller to other BUS subscribers: Use electrical cable with the minimum specification H05 VV-... (NYM-I...). Permissible cable lengths from the BUS-enabled Heatronic 3 to the controller: Cable length Cross-section 80 m 0.
Commissioning (for installers only) 4 Commissioning (for installers only) 1 Switch on the system. 2 During first commissioning or after a global reset (resetting all adjustments): B Confirm the flashing code 1 HC by pressing . 3 System configuration starts automatically, and lasts approximately. 60 seconds during which time AC will be displayed.
Operation Operation 6 720 613 554-02.1R 5 mode 1 2 Fig.
Operation Controls 1 Rotary selector : - Turn = Adjust value - Press = Confirm setting/value 2 Mode key: - Change operating mode - Accessing user level = hold down for approx. 3 seconds - Accessing installer level = Hold down for approx.
Operation 5.1 Changing the operating mode B Briefly press mode until the required operating mode is displayed. = constant Comfort = constant Economy = constant Frost The selected operating mode is only enabled if the heating operation is not blocked. 5.2 Changing the required room temperature Use this function if you want to change the required room temperature by way of an exception, e.g. for the duration of a party.
Operation 5.3 Changing the standard setting of the required room temperature Use this function if you want to permanently change the required room temperature away from the standard setting. B Accessing user level: Hold down mode for approx. 3 seconds until – – is displayed.
Operation B Briefly press to save the value. B Press mode until the current room temperature is displayed. 5.4 Adjusting the installer level (for installers only) The installer level is exclusively designed for installers. B Accessing installer level: Hold down mode for approx. 6 seconds until – – – is displayed.
Operation 5.4.1 Changing the code (parameter: 5A p) Setting range: 1 to 10 Use this parameter if you want to adjust the code after commissioning: B For systems with a single heating circuit: Select code 1. Only one FR 10 can be used per heating system. 5.4.
Operation 5.4.3 Adjusting the room temperature sensor (parameter: 6A p) Setting range: – 3.0 °C (K) to +3.0 °C (K) Use this parameter if you want to correct the displayed room temperature. B Position a precision instrument near FR 10. The precision instrument must not transfer any heat to the FR 10. B Keep other heat sources, such as sunlight, body heat etc. away for one hour. B Adjust the displayed room temperature correction value. 5.4.
Operation 5.4.5 Selecting amplification factor V (parameter: 6C p) Setting range: 40 % to 100 % Subject to changes in room temperature, the amplification factor V influences the heat demand. B Selecting amplification factor V: – ≤ 50 %: Select a lower factor to reduce the influence on the heat demand. The selected room temperature is achieved after a longer time with only little overshoot. – ≥ 50 %: Select a higher factor to increase the influence on the heat demand.
Operation 5.5 Selecting the heating program B Select the heating program with start and stop switching times at the time switch (Æ time switch operating instructions). 5.6 Frost protection The heating (circuit pump) starts if the room temperature in the room where the FR 10 is installed falls below 4 °C or the flow temperature falls below 8 °C. The heating system is started and stopped accordingly to maintain the room temperature of 4 °C or the flow temperature of 8 °C.
Troubleshooting 6 Troubleshooting If the boiler has developed a fault, the display will show, for example, EA. E. Here, EA means a boiler fault; the full stop . means an external fault; E means error (= fault). If the FR 10 has developed a fault, the display will show, for example, 03 E. Here, 03 refers the the fault number at the FR 10 and E stands for error (= fault): B Contact your installer. If several faults are active, the fault with the highest priority is displayed.
Troubleshooting Fault Cause Remedy Required room temperature not achieved. Thermostatic valve(s) are not opened sufficiently. Fully open the thermostatic valve(s) or ask your installer to check the valves. Central heating temperature Set the central heating control on the boiler set too temperature controll low. higher. Air in the heating system. Bleed radiators and vent the heating system. Required room FR 10 installed in an unfatemperature vourable location, e.g. extergreatly exceeded.
Troubleshooting If the fault persists: B Call your installer or customer service and inform them of the fault, quoting the appliance details (from the type plate). Appliance details Type: ........................................................................................................ Part number: ........................................................................................................ Date of manufacture (FD...): ........................................................................
Tips on saving energy 7 Tips on saving energy • Regulate the temperature in adjacent rooms via thermostatic valves. • External heat in the room where th FR 10 is installed (e.g. solar gain, stove etc.) can result in too little heating in adjacent rooms (the heating system remains cold). • Much energy can be saved by reducing the room temperature via economy phases. Reducing the room temperature by 1 K ( °C) enables up to 5% energy to be saved.
