Quick setback
Heating
Synco RMH760
Quick setback achieves the new setpoint earlier for a change to
room operating mode.
– Significantly reduces the operating hours of the heating circuit
pumps and thus its energy consumption.
Quick setback is enabled when changing room operating mode from
Comfort or Precomfort to Economy or Protection mode, the heating
circuit pump is shut down and the heating circuit mixer is closed. The
heating circuit remains shut down until the desired room temperature
is achieved.
The function is ended, when the room temperature achieves the new
setpoint or it is switched to Comfort or Precomfort operating mode.
2 cases:
• Room temperature sensor available: Actual room temperature is
used to abort quick setback.
• Room temperature sensor not available: Controller uses room
model. The setback period depends in this case on the outside air
temperature and the building time constant.
Function is enabled as factory setting.
