Red text is parameter mode 2.
P1:
Programme version control panel. Not adjustable.
P2:
Programme version motherboard in the unit. Not adjustable.
P5:
Governing entity.
1 = Control panel.
2 = Modbus.
3 = Modbus & Manöverpanel.
P7:
Acknowledgement of alarm via control panel. On = Acknowledgement.
Automatically returns to OF after acknowledgement.
P9:
Location of the supply air fan.
1 = Supply air upper fan.
2 = Supply air lower fan.
Depending on the model, for A50S, A70T, A100S, A200S, A400S, setting 1 always applies.
P11:
Supply air fan speed ”Economy”.
P12:
Exhaust air fan speed ”Spar”.
P14:
Supply air fan speed ”Comfort”.
P15:
Exhaust air fan speed ”Comfort”.
P17:
Supply air fan speed ”Forced”.
P18:
Fan speed exhaust air ”Forced”.
P21:
Setting the temperature.
P23:
Activation of temperature reduction in ”Save”.
P25:
Choice of principle for temperature control.
P31:
Reheat battery activated.
P41:
Cooling forcing. Capacity increase of fans in case of cooling demand.
P43:
Cooling recovery. The rotary heat exchanger starts when the exhaust air temperature is lower than the outdoor air temperature.
P45:
Free cooling via outside air.
P47:
Defrost function, number of hours between each defrost, OF = defrost off.
P48:
Defrost function, outside temperature in minus degrees when defrost is activated.
P51:
Fan speed supply air “External control 1”.
P52:
Fan speed exhaust air “External control 1”.
P53:
Temperature “External control 1”.
P55:
Fan speed supply air “External control 2”.
P56:
Fan speed exhaust air “External control 2”.
P57:
Temperature “External control 2”.
P70:
Humidity reduction, the function starts when the outdoor air temperature falls below the set value, a hygrostat with potential-free contact can be connected to ”external control 2” if a certain humidity level must also be reached before the function starts
OF = deactivated.
1=Temperature controlled.
2=Temperature and hygrostat controlled.
P71:
Moisture reduction aggressiveness, higher value the more aggressive (less moisture recovery).
P72:
Humidity reduction activation temperature in degrees below zero Celsius.
P81:
Service alarm.
OF=Service alarm deactivated.
1-24 number of months between service alarms.
P91:
Fan monitoring.
A390T, A400S, A600S/T, A900 S/T = 2.
Other aggregates = 1.
P92:
Prioritisation.
1 = Outer.
2 = Last input.
3 = Last input with prio switched off.
A70T with cooker hood 251 = 3.
A70T with cooker hood 392 = 1.
All other units =1.
P93:
Max limitation of supply air fan.
P94:
Switch-off delay of rotary heat exchanger in minutes.
P95:
Emergency drift.
