Control conditions, cold outdoor air
■
When the ambient air temperature (channel T1)
drops below the set temperature in channel A7 the
heat pump stops and indicates 03 in channel S1. Both
the additional relay and the downtime relay are then
activated at the same time.
■
If the ambient temperature sensor registers a temper-
ature that is at least 2.1 °C higher than the set tem-
perature in channel A7, a time counter starts.
■
When the time counter has reached 45 minutes, both
the additional relay and downtime relay deactivate
to obtain a more comfortable temperature for the
compressor to start at.
■
When a further 15 minutes have passed, the com-
pressor is permitted to start and the additional relay
activates a few seconds later. However, the downtime
relay is deactivated.
■
If the ambient temperature at any point during the
total 60 minutes falls below channel A7 + 2.1 °C the
counter is reset. It does not start counting again un-
less the temperature is sufficiently high once again.
B = Set temperature for cold outdoor air (channel A7).
A = Set temperature for cold outdoor air + 2.1 °C.
1. The ambient temperature (channel T1) drops below
the set temperature in channel A7 (B). The heat
pump stops and both the relays are activated.
2. The ambient temperature is 2.1 °C) above the set
temperature in channel A7 (A). A time counter
starts from 0.
3. The ambient temperature falls below A. The timer
is reset and stopped.
4. The ambient temperature returns to above A. The
time counter starts again (from 0).
5. The time counter has counted to 45 minutes. Both
relays are deactivated.
6. The time counter has counted to 60 minutes. The
compressor is permitted to start again.
NOTE
It is heat pump’s ambient temperature sensor
that applies.
