Danfoss GreenCon RC-C2/C4 Room Thermostat Installation Guide Overview

Summary of Contents

• Page 1: Installation guide for GreenCon RC-C2/C4 room thermostat.
• Page 2: Installation must be done by an authorised electrician. The room thermostat should be installed at approx. 1.5 m above floor and where the effects of sunlight, draught or other heat sources are avoided. Carefully remove the cover before connecting the wire. Connect the wire before mounting the back plate to the wall box using the enclosed screws. Mount the cover to the back plate after installation. Refer to the dimensions and wiring diagrams for proper installation. Follow the illustrations to complete the wiring for SPST on/off control. Wiring for RC-C4 and RC-C2 models is provided in the diagrams. Wiring for SPDT on/off control is also illustrated for both models. User guide can be downloaded from the specified website.
• Page 3: Installation guide for GreenCon RC-C2/C4 includes error codes and descriptions. Error codes include E1 for short circuit of sensor, EE for EEPROM chip error, Lo for temperature lower than 0°C, and Hi for temperature higher than 50°C. Correct wiring is essential; confirming L and N before wiring is recommended. Avoid removing too much insulation from the wire to prevent short circuits. Ensure screws do not touch the wire when fixing the thermostat to avoid damage. Mount the thermostat after painting to prevent dust or paint from damaging the PCB. The maximum load of the relay is 3 A (resistive) or 1 A (inductive).
• Page 4: Installation guide for GreenCon RC-C2/C4. The relay will be damaged if the load exceeds the limit. Don’t cover the thermostat, for instance by hanging towels directly in front of it. The room thermostat should be connected to the corresponding actuator and valve in individual room temperature control. Technical specifications include CE marking and compliance with EN60730. Ambient temperature range is 0 - 45 °C. Max load for inductive is <1 A and for resistive is <3 A. Power consumption is 2 W. Power supply requirements are 85-250 Vac, 50/60 Hz. Room temperature set range is 5 - 35 °C with shell material made of ABS + PC.

• Page 8: Installation guide for GreenCon RC-C2/C4 includes instructions for locking and unlocking the keyboard, resetting the thermostat, and auto-switching between heating and cooling. To lock the keyboard, press and hold “M” and short press “>” within 6 seconds. To unlock, repeat the same steps. To reset the thermostat, press and hold both “M” and “<” and “>” for 10 seconds during power off. The auto switch function controls heating and cooling based on parameters P16, P17, and P19. The temperature is managed by the set temperature, with the dead zone determined by parameters P16 for normal mode and P17 for ECO mode. If P18 is off, the fan is controlled by the fan speed selection. If P18 is on, the fan is disabled during heating and controlled by the fan speed selection during cooling. For 5-2 day programming, configure P01 to “02” in parameter settings to enable automatic temperature changes four times per day.
• Page 9: Installation guide for GreenCon RC-C2/C4. Both setting temperature and event time can be modified. Programming function allows users to define temperature setting for 4 time periods during workdays and weekends. Default setup includes starting time and temperature for each period. Programming of workday setup involves adjusting starting hour and temperatures for events. Pressing specific buttons confirms adjustments during programming. Programming for weekend setup follows the same steps as workdays. GreenCon will automatically change setting temperature according to the setup.
• Page 10: Installation guide for GreenCon RC-C2/C4 includes parameter setting instructions. To enter parameter setting mode, long press “M” for 6 seconds. Short press “M” to select a parameter; use “<” or “>” to adjust the value. Factory parameter definitions include programming options and timer settings. Maximum room temperature can be set between 5-35°C, with a default of 30°C. Minimum room temperature can also be set between 5-35°C, with a default of 5°C. Frost protection can be turned ON or OFF, with a temperature range of 5-17°C. Default heating temperature is set at 20°C, while the default cooling temperature is 25°C. Default heating temperature for ECO mode is set at 15°C. Danfoss Heating Solutions is referenced in the document.
• Page 11: Installation guide for GreenCon RC-C2/C4 includes factory settings and parameter definitions. The default cooling temperature for ECO mode is set at 28°C with a range of 5-35°C.

• Page 13: Installation guide for GreenCon RC-C2/C4 is provided. Installation must be performed by a qualified electrician. The indoor thermostat should be installed approximately 1.5 meters above the floor, avoiding sunlight, airflow, or other heat sources. Carefully remove the front cover before installation. Connect the wires using the included screws before securing the backplate to the junction box. Refer to the dimensions in the provided diagrams. Wiring terminals are detailed in the specified diagrams. Follow the instructions for wiring based on whether the valve is a two-wire or three-wire valve. Diagrams illustrate the wiring for both RC-C4 and RC-C2 models. Ensure all connections are completed as per the guidelines.
• Page 14: Installation guide for GreenCon RC-C2/C4 includes important error codes and their meanings. Error codes such as E1 indicate room temperature sensor failure, while EE signifies EEPROM failure. Lo and Hi indicate room temperatures below 0℃ and above 50℃, respectively. Proper wiring is crucial; it is recommended to confirm L and N with a device before wiring. Avoid removing excessive insulation from wires to prevent short circuits. When securing the indoor thermostat with screws, ensure they do not press against or contact the wires. Install the indoor thermostat after painting to prevent dust or paint from damaging the PCB. The maximum load for the relay is 3 A for resistive loads and 1 A for inductive loads. Do not cover the thermostat, such as hanging towels directly in front of it. For zoned temperature control, ensure the room with the thermostat corresponds to the circuit with the valve.
