Section 1: General System Information Modular System The Uponor Climate Cŏntrol™ Network System is an innovative technology that integrates and controls the complete heating, ventilation and air-conditioning (HVAC) system of a home or building. This system is modular in design and can be scaled to fit any HVAC mechanical system.
Communication and Networks The system works by passing data through a series of communication networks. A fully implemented system uses four networks: thermostat, zone control, field device and ethernet, described in Table 1-2. Network Description Thermostat Network The thermostats on a DZCM run on a network to transfer readings and setpoints between the thermostats and the rest of the control system.
Section 2: System Zoning Hydronic Zones (Radiant Zones) A hydronic zone is an area for which a set of hydronic devices delivers heat. Each thermostat is assigned a different hydronic zone and zone number within a system. A hydronic zone can include various combinations of hydronic equipment.
When a thermostat becomes the master thermostat, an icon appears on the thermostat’s screen (see Figure 2-3). This icon signals the user that the thermostat is now the master thermostat. Figure 2-3: Master Thermostat Icon The other, non-master thermostats in an air zone will display AU (automatically controlled) when the user attempts to change a setpoint. If you want that thermostat to take over as the master, press the (+) or (–) button again and that thermostat will become the master for that air zone.
Section 3: System Functions The Uponor Climate Cŏntrol Network System can direct operations of the HVAC systems in a home or building. Radiant Floor Heating Radiant floor heating may be controlled through and associated with any combination of: • A single zone valve • Zone pump • Mixed water temperature channel • Actuator-controlled manifold valve You can set up associations among thermostats, zones and radiant floor heating in the UCT.
humidity. If a dehumidifier is set up in the air zone, the dehumidifier and its associated fan will turn on. When the system calls for humidification, the humidifier and its associated fan will initiate. Carbon Dioxide Control Carbon dioxide is a naturally occurring gas that is colorless, odorless, incombustible and formed during combustion and respiration. Therefore, carbon dioxide is a good indicator of stale or dirty air. It is unhealthy and uncomfortable to be surrounded by too much carbon dioxide.
Section 4: Boiler Operation The Network System starts and maintains the boiler after establishing the required demand from the thermostats, mix channels, snow melt and DHW. Supply Water Temperature Control The boiler target temperature is calculated continuously from the hottest water demand on the system. Refer to the boiler manufacturer’s literature for information about the minimum and maximum water temperature settings.
The user can define the tank setpoint with the UCT, the system website or the Uponor Touch Panel Interface. If controlling two tanks, you can schedule them individually. During DHW scheduled on times, the system will keep the tank within 9°F (5°C) of the user-defined setpoint. In scheduled off periods, the tank is not controlled and will eventually fall to room temperature. Snow Melting DHW Recirculation The Network System supports DHW recirculation if there is only one DHW tank in use.
Semi-automatic Snow-melt Activation Manually start a snow-melt system by pressing a momentary switch. Mount a remote switch indoors for this purpose or use the manual switch on the Snow Melt Control (A9013051). Hold the switch for at least five seconds to guarantee activation. The snow-melt system will run for a set period of time once it is manually activated. You can adjust this time via the UCT.

Section 5: System Modes An air zone can be set to the following four modes: Heat, Cool, Auto and Off. Heat Mode If an air zone is in Heat mode, it will only supply heat to the space. In Heat mode, the system is driven by thermostat heat setpoints only. Cool Mode If an air zone is in Cool mode, it will supply cooling to the space. However, the system may apply heat to radiant floors for floor warming while the system is cooling the air.

Section 6: Schedules and Calendars Multiple scheduling and calendar functions are built into the Uponor Climate Cŏntrol Network System. All schedules and calendars are adjustable from the UCT or the Touch Panel Interface. Thermostat Schedules There are 16 thermostat schedules available. Each schedule may be configured differently, and each thermostat may be configured to follow any of the 16 schedules.

Section 7: Error Detection and Alarm Notification The Network System can detect and notify you about various problems occurring in your heating, cooling and ventilation system. When an alarm activates in the system, it sends an e-mail to the Uponor North American server. The e-mails are then automatically sorted and relayed to a user-defined e-mail list. To change the e-mail list for your installation, contact the Uponor Climate Cŏntrol Network System Administrator at (952) 997-5333.

Section 8: Protection Limits Many protection-level functions are built into the Uponor Climate Cŏntrol Network System to keep you and your home as safe and comfortable as possible. In any mode, conditions throughout the Network System are monitored to protect the residence. In normal operation, these protection limits should never be reached.

Appendix A: Connecting a DZCM or Field Device Network Wiring When wiring these networks, refer to the following rules. DZCM and field device networks are generally wired with Cat5 wire. These networks can be wired and arranged in a wide variety of configurations. You can use a Network System Y-Connector (A9011003) at any point in the Uponor Climate Cŏntrol Network System to create another network leg, which can be very useful in homes with wings or many floors. 1.
Troubleshooting TX and RX light-emitting diodes (LEDs) locations: • On the DZCM, the LEDs are located immediately above the map button. • On the field devices, the LEDs are located just above and to the left of the manual switch. Monitor both the TX and RX LEDs to assess the operational status of the network communications. See Table A-1 for LED definitions.
Appendix B: Temperature Sensor Troubleshooting Temperature Resistance All the temperature sensors in the Uponor Climate Cŏntrol Network System are 10K J-curve sensors. If a sensor is reporting a value that does not seem accurate, test the sensor with the data in Table B-1. Note that the sensors maintain a tolerance of +/– 0.54°F (+/– 0.3°C). Temperature R Temperature R Temperature R ºC Ω ºC Ω ºC ºF Ω ºF ºF -45.0 -49.0 471985.0 9.0 48.2 20882.0 63.0 145.4 2235.0 -42.0 -43.

Appendix C: Mix Channel Settings The Uponor Climate Cŏntrol Network System supports up to five mix channels per installation. Each mix channel uses a supply-and-return sensor to control the average temperature in the output device. The Network System uses an internal function, DeltaT (∆T), for calculating temperature differentials between the supply and return legs of an output device.
Mix Limits Each mix channel has upper and lower limits to prevent the mix output, as read by the mix channel supply sensor, from reaching above or below a certain value. • Minimum temperature (MinT) is the minimum allowable temperature the mix channel can produce. MinT limits the mix temperature when the outdoor temperature rises above the warm weather outdoor temperature. • Maximum temperature (MaxT) is the maximum allowable temperature the mix channel can produce.
Appendix D: Making a Cat5 Cable Refer to the following instructions to make a Cat5 cable. Note: There are two protocols for making Cat5 (or ethernet) cables — T568A and T568B. The Uponor Climate Cŏntrol Network System uses T568B. 2. Using either the attachment on the RJ45 crimp tool, a knife or wire strippers, strip approximately ½-inch of outer insulation from the wire cable (see Figure D-2).
4. Arrange the wires from left to right in the following order (see Figures D-4 and D-5). 6. Trim the tips of the wires so they are even (see Figure D-7). Make sure there is about ½-inch of wire to insert into the connector. Pin Number Color Figure D-4: Wire Arrangement Figure D-7: Trimming the Wires 7. Holding the wires with the white/orange on the left and the brown on the right, slide on the RJ45 connector. Ensure the metal pins are facing up and the locking tab is facing down (see Figure D-8).
8. Make sure all wires reach the end of the RJ45 connector. Rotate the plug for visual inspection (see Figure D-9). Figure D-9: The Wiring Assembly 11. Test the cable before installation (see Figure D-11). Refer to the cable tester manufacturer’s literature for proper cable testing instructions. Figure D-11: Testing the Cable 9. Insert the assembly into the crimper and tightly crimp the connector (see Figure D-10). Figure D-10: Crimping the Wire Assembly 10.
