Off mode works slightly differently, depending on what type of zone is being controlled:
- Heating: Radiator or Underfloor zones in Off mode will not call for heat unless the measured temperature drops below 4°C. This is explained in the on-screen message when you enter Off mode.
- The 4°C is customisable, and can be changed from the Zone Setup page.
- On/off type: The zone will stay turned off, and not try to heat unless changed into timer/override mode.
