Heating settings

IMPORTANT:

Do not change the heating settings without consulting an HVAC expert.

  1. Select Settings:
  2. Select Expert settings with the arrow buttons.
  3. Select OK:
  4. Select Heating settings with the arrow buttons:
  5. Select OK:

    The Heating settings screen opens:

  6. Select the heating method with the arrow buttons:

    The options are:

    • Electric resistor
    • Liquid radiator
    • Not in use
  7. Select the additional heating method with the arrow buttons:

    The options are:

    • Electric resistor
    • Liquid radiator
    • Not in use
  8. Set the temperature limit of the heating season using the Plus and Minus buttons. The adjustment range is 0°C to +19°C. The factory setting is +12°C.

    The heating season setting specifies the outdoor temperature limit below which the ventilation unit uses the post-heating resistor as needed to heat the supply air. The HR cell bypass is then disabled.

    When the outdoor air temperature is below the set value:
    • the supply air is heated with post-heating as needed
    • HR cell bypass is disabled.
    When the outdoor air temperature is above the set value:
    • post-heating resistor is disabled
    • HR cell bypass and partial bypass can operate when required.

    Example: If the heating season limit is set at +12 °C and the outside temperature is below that, the ventilation unit can use post-heating to maintain the set supply air temperature. The heat recovery cell bypass is not in use.
