Can I use the Danfoss REPI thermostat to control both heating and cooling equipment?
Yes. The Danfoss REPI can control room temperature via electric modulating valves with 0-10VDC or 4-20mA control signals, or floating control and damper actuators in both heating and cooling modes. User Manual, p. 1
What do the buttons on the Danfoss REPI thermostat control?
One button turns the unit on and off. Others adjust setpoint temperature, change working mode, select fan speed, and access the parameter menu. User Manual, p. 2
How does auto fan speed differ from fixed fan speed on Danfoss REPI?
Auto speed adjusts fan output based on temperature difference from setpoint. Fixed speeds run at one constant level regardless of temperature. User Manual, p. 2
How do I set the sleep timer?
Press the designated button for 3 seconds until the sleep display appears, then adjust the countdown time up to 48 hours and confirm.
- Press the sleep button for 3 seconds until the sleep display shows.
- Use the adjustment buttons to set desired sleep time up to 48 hours.
- Thermostat returns to working status after 5 seconds with the sleep icon flashing. User Manual, p. 2
