External setpoint device
 No
 TG-R4-PT100
 TBI-PT1000
An external setpoint device, e.g. TBI-PT1000 or TG-R4/PT1000 can be connected.
The setpoint device must follow the PT1000 resistance curve. The unit is
connected to the analogue input signal ”External setpoint device”.
Control input switch Summer/winter
 No
 Yes
To control from BMS system if the building should be in Summer or Winter control
mode. This is then controlled via Digital input
Cooling recovery mode
 Off
 On
If the cooling recovery has been configured, there is a cooling requirement and the
extract air temperature is a settable amount lower than the outdoor temperature,
cooling recovery can be activated. When cooling recovery is activated the heat
exchanger and damper sequence output signal will be activated in the cooling
demand. The function also activates the heating function “Free heating”: if heating
is required and the outdoor temperature is higher than the extract air temperature,
outdoor air will primarily be used.
Cooling recovery Limit
 Difference limit value
Temperature difference between Extract air and Outdoor (intake) air.
Temperature compensation related fan speed
 None
 Low
 High
 Low & High
Setpoint adjustement for Low speed and/or high speed.
