Black text is parameter mode 1.

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 & Control Panel.

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.

Exhaust air operation in case of A-alarm.

Only the exhaust fan is in operation.

P99:

21: Heat exchanger on (shows speed, rpm).
31: Heating coil on and supply air fan on spar (showing On).
35: Relay damper control on (shows On).
36: Cooling control relay, active (shows On).
37: A-alarm relay, active (showing On).
38: B alarm relay, active (showing On).
41: Shows supply air temperature (displays °C).
42: Displays exhaust air temperature (shows °C).
43: Shows outdoor air temperature (displays °C).
61: Heat exchanger, heating coil, supply and extract air fan on forced (showing On).

Set values are maintained after a power cut.
