Menu 9.1.10 Cooling
The type of cooling system is set here. The
selectable modes are: ”Off”, ”HPAC base card”,
”HPAC expansion card 1”, ”Cooling accumulator”,
“PKM 2 pipes” and “PKM 4 pipes”. The factory
setting is “Off”.
Select “Cooling accumulator”.
Menu 6.8.1 Cool acc temperature
Shows the current temperature at the cooling
accumulator sensor (KBack).
Menu 6.8.3 Cooling curve
The selected curve slope (cooling curve) is shown
here. The value can be set between 1 and 3. The
factory setting is 2.
Menu 6.8.4 Offset cooling curve
The selected cooling curve offset is shown here.
The value can be set between -10 and +10. The
factory setting is 0.
Menu 6.8.5 Start temp. heating
Outdoor temperature (menu 4.0) at the outdoor
sensor (UG) when the heat pump is permitted to
produce heat. The value can be set between 0
and 30 °C. The factory setting is 20 °C.
Menu 6.8.6 Start temp. cooling
Outdoor temperature (menu 4.0) at the outdoor
sensor (UG) when the heat pump is permitted to
produce cooling. The value can be set between 0
and 30 °C. The factory setting is 25 °C.
Menu 6.8.7 Temp. to cool. acc.
The desired temperature for the cooling accumu-
lator is set here. The value can be set between 0
and 20 °C. The factory setting is 13 °C.
Menu 6.8.9 Min. flow temp.
The lowest flow temperature in cooling mode. The
value is adjustable between 2 and 65 °C. The fac-
tory setting is 5 °C.
Menu 6.8.10 Period time shunt
The time period for the shunt (SV-K) is chosen
here. Adjustable between 1 and 500 seconds.
The factory setting is 60 seconds.
Menu 6.8.11 Shunt intensification.
The amplification for the shunt (SV-K) is chosen
here. For example, a 2 degree difference between
the flow line and the calculated flow line with 5
in amplification gives 10 secs/min controlling the
shunt. The value can be set between 1 and 10.
The factory setting is 1.
