Overrun time cond pump
When the compressor is switched off, the condenser
pump continues to run for the set overrun time.
Compressor off time min
For the same reason, the compressor remains
switched off for the minimum period of time set here.
Switch-off temperature maximum if the flow or the
return temperature exceeds the maximum switch-
off temperature, the compressor will be switched
off.The heat pump is switched on again when the
temperature at both sensors has dropped by the
"Switching diff return temp" below the maximum
switch-off temperature and the minimum off time
has elapsed.
Switch-off temp max
If the flow or the return temperature exceeds the
maximum switch off temperature, the compressor
will be switched off.
Example (line 2844):
Floor heating system = 55 °C
Higher temperature radiator = 65 °C
Locking time stage 2
When compressor is restarted, the time which
keeps minimum capacity can be adjusted.
Efficiency becomes better; however, the time of
rising capacity becomes long.
Compressor mod run time
Compressor mod run time means the time of
compressor frequency indication changed from
minimum to maximum.
If this setting value changes to small, compressor
frequency changes more quickly.
Warning:
This setting value is too small, the efficiency is
decreased due to the compressor frequency
changes frequently.
Release integral electric flow
After the release of the 1st stage (heater 1:
on, heater 2: off), the controller compares the
temperature measured with the point of engagement
and forms an integral and includes a possible deficit
of heat. Once the value of the integral reaches
the maximum value (line 2882), the 2nd stage
is engaged (heater 1: off, heater 2: control). The
controller continuously compares the temperature
measured at the point of engagement and new
features to the deficit of heat in the full release.
When the full release reaches the value set (line
2882), the 3rd stage of the heater is triggered (heater
1: on, heater 2: Control).
Release electric flow below OT
The heater will be activated only if the attenuated
outdoor temperature is below the temperature set
here.
Warning:
This setting 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 not
switched on.
