Danfoss GreenCon RC-T2/T4 Room Thermostat Installation Guide Overview

Summary of Contents

• Page 1: Installation guide for GreenCon RC-T2/T4 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 installation. 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 for installation guidance. Consult the wiring diagram for proper connections. Follow the illustrations to complete the wiring for RC-T4 and RC-T2. User guide can be downloaded from the specified website. Ensure all steps are followed for correct installation.
• Page 3: Installation guide for GreenCon RC-T2/T4 includes error codes and descriptions. Error codes: E1 indicates a short circuit of the sensor. EE signifies an EEPROM chip error. Lo indicates a temperature lower than 0°C. Hi indicates a 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-T2/T4. 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 EN60730 approval. 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 with a power supply of 85-250 Vac, 50/60 Hz. Room temperature set range is 5 - 35 °C. Shell material is ABS + PC.

• Page 6: Installation guide for GreenCon RC-T2/T4 outlines key operational features. Power options include On/Off and Eco mode. To turn on, press the power button; to turn off, hold the button for 2 seconds. Eco mode can be accessed with a short press of the power button. Mode selection allows changing between cooling, heating, or ventilation. Temperature can be adjusted by pressing the corresponding buttons. The SET icon indicates when temperature setting is in progress. Fan speed can be selected from options including Low, Med, Hi, and Auto. In Auto mode, fan speed adjusts based on the temperature difference. Default setting for fan speed is Close when not in use.
• Page 7: Installation guide for GreenCon RC-T2/T4. Time setting and ON/OFF timer instructions provided. Long press to start adjusting the hour, minute, and weekday. Timer On/OFF setting can be configured after time setting. Steps to adjust timer ON and OFF hours and minutes outlined. Instructions to cancel the ON/OFF timer function included. Keyboard lock feature mentioned. Details on parameter P11 for setting temperature referenced. Danfoss Heating Solutions noted as the manufacturer.
• Page 8: Installation guide for GreenCon RC-T2/T4 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 then short press “>” within 6 seconds. To reset the thermostat, press and hold both “M” and “<” and “>” for 10 seconds during power off. The auto switch between heating and cooling is controlled by 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. For heating and cooling, 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. The programming feature allows for 5-2 day programming by configuring P01 to “02”. When enabled, the system automatically changes the setting temperature four times per day.
• Page 9: Installation guide for GreenCon RC-T2/T4 includes instructions for modifying temperature settings and event times. The programming function allows users to define temperature settings for four time periods during workdays and weekends. Default setup includes starting times and temperatures for each period: 7:00 at 18°C/28°C, 9:00 at 22°C/26°C, 18:00 at 18°C/28°C, and 21:00 at 15°C/30°C. To program workday setup, long press the designated button for 5 seconds until the workday icon displays. Users can adjust the starting hour of the first event and confirm the selection. Adjustments can also be made for heating and cooling temperatures during the first event. This process should be repeated for the next three events. For weekend setup, after programming workdays, the weekend icon will appear on the screen. Users should repeat the steps to set starting time and temperature for weekends. GreenCon will automatically change the setting temperature according to the programmed setup.
