If the BAH solution with brine pre-heating is selected:
↳
Frost protection
↳
Frost protection heat exchanger Setting: BAH
↳
BAH minimum temperature (ºC) Settings:
Standard setting:
Description:
-10 ↔ 10°C
5°C
At an outdoor temperature below the minimum
temperature, the circulation pump in the BAH solution
starts up as a safeguard against icing in the
counterflow heat exchanger.
↳
BAH maximum temperature (°C) Settings:
Standard setting:
Description:
15 ↔ 35°C
25°C
At an outdoor temperature above the maximum
temperature, the circulation pump in the BAH solution
starts up in order to cool the outdoor air and prevent
the dwelling from warming up.
(At a temperature between the minimum and
maximum temperatures, the circulation pump will be
inactive).
↳
BAH regulatory deadband (°C) Settings:
Standard setting:
Description:
0 ↔ 10.0°C
2.0°C
The regulatory deadband for temperature regulation.
De-icing the heat exchanger:
↳
De-icing heat exchanger
↳
Frost protection below temp. (°C) Settings:
Standard setting:
Description:
-10 ↔ 1°C
1°C
Indicates when the control system is to start
monitoring of the heat exchanger via the T4
temperature sensor after the heat exchanger.
↳
Maximum time de-icing (min) Settings:
Standard setting:
Description:
10 ↔ 90 minutes
25 minutes
Indicates how long the unit needs to perform the de-
icing function for the heat exchanger.
↳
Minimum time between de-icing
(min)
Settings:
Standard setting:
Description:
15 ↔ 180 minutes
30 minutes
Indicates the minimum time between de-icing the heat
exchanger.
↳
Extract air fan during de-icing Settings:
Standard setting:
Description:
Level 1 / Level 2 / Level 3 / Level 4
Level 2
Indicates the speed level at which the extract air fan is
to run during de-icing of the heat exchanger.
↳
Supply air fan during de-icing Settings:
Standard setting:
Description:
Normal / Extract air
Extract air
Indicates how the supply air fan is to run during de-
icing:
Normal: The supply air fan continues running at the set
level.
Extract air: The supply air fan runs at the same level as
the extract air fan.
