• Compressor mod run time
Compressor mod run time means the time of compressor frequency indication changed from mini-
mum to maximum. If this setting value changes to small, compressor frequency changes more
quickly.
WARNING
If this setting value is too small, the efficiency is decreased due to the compressor frequency
changed frequently.
• Release integral electric flow
After the release of the 1
ture measured with the point of engagement and forms as integral and includes a possible deficit
of heat. Once the value of the integral reaches the maximum value (line 2882), the 2
engaged (heater 1: off, heater 2: control). The controller continuously compares the temperature
measured at the point of engagement and new features to deficit of heat in the full release. When
the full release reaches the value set (line 2882), the 3
on, heater 2: control).
• Flow electricity release at OT
The heater will be activated only if the attenuated outdoor temperature is below the temperature
set here.
WARNING
If this setting value is too low, there may be a feeling of discomfort due to the fact that the heat
pump is unable to meet the heating requirements alone at low outdoor temperatures, and heaters
are switched on.
• Maximum setpoint HP DHW charge
The heat pump setpoint is limited to the parameterized value during warm water charging. The
function can be switched off. If the flow temperature is higher than the parameterized value, the
DHW charging with heat pump will be stopped and finished with electrical immersion heater or
auxiliary heat generator.
• With electrical utility lock
This setting relates to input EX1 (load-shedding or peak day clearing) and allows the electric
heaters to be locked as follows:
– Locked
The heat pump and all electric heaters are locked, both heat pump stages and the DHW tank
electric heater. Only the boiler backup, if installed, continues to operate.
– Released
The heat pump operates and all electric heaters are locked, both heat pump stages and the
DHW tank electric heater. The boiler backup, if installed, continues to operate.
