PTC Electric heating elements (PTC elements "positive temperature coefficient") fulfil
three functions:
•
Individual room temperature control,
•
Emergency operation,
•
peak load covering.
A heat pump priority circuit ensures an optimized normal operation of the PTCs.
Adjustment range: 0 - 60 minutes
Default setting: 45 minutes
Start delay The adjustable start delay prevents early switching on of the heating elements and
opens a time window for the heat pump to provide the requested heat amount
alone. The correct setting of the start delay ensures an optimized energy efficiency.
Defrosting HP
Factory settings 20 %
Defrosting of the heat pump is done by a reverse cycle, i.e. during this time cold
supply air is blown in for a short time. The PTCs will be controlled to counteract.
Switch-off point Factory settings -20°C
If the external temperature reaches the set value, the heat pump switches off and
emergency operation will be activated.
Setpoint preheater Factory settings -10°C
If a preheater is installed (Accessories), here, set the temperature at which the
heater starts.
P-Gain preheater Default setting: 2
The preheater can be steplessly adjusted from 0 ... 100%.
Using this value, it is possible to set the speed at which the power increases.
NOTE
A preheater is recommended for cold regions. This ensures operational safety for the air heat pump at extremely cold
external temperatures.
10.8.1.3 Night cooling
Night cooling With the setting Night cooling ( free cooling ), the combi unit Genius passively cools
(under certain conditions) the house/apartment during the night in summer.
Settings: No / Yes
Default setting: No
Night cooling
Activation night cooling No
Activated at outdoor temperature 22 °C
Max. outdoor temp. night 18 °C
Min. outdoor temp. night 5 °C
min. room temperature 20 °C
NOTE
Both night cooling settings (enabled / disabled) stop the rotation heat exchanger when the following conditions occur
simultaneously:
•
The outdoor temperature is lower than the extract air temperature.
AND
•
The actual room temperature is above the setpoint temperature (see Rotor Settings).
The heat recovery and outdoor air heating will be disabled. Colder outdoor air enters the building. This is done during
day and at night without night cooling function in each set ventilation level.
