A geo-heat exchanger can be connected to the
Ubiflux+.
The geo-heat exchanger can be connected to con-
nection no. 5 (GND), no. 6 (24V) and no. 9 (0-10V)
of 9-pole connector; this 9-pole connector is directly
accessible at the top of the appliance. Connect the
outside temperature sensor on 7 and 8 of the 9-pole
connector.
When the geo-heat exchanger is connected, it is
no longer possible to connect a postheater to the
Ubiflux+!
A = Minimum temperature
B = Maximum temperature
I = To dwelling
II = To atmosphere
III = From dwelling
IV = From atmosphere
When using a geo-heat exchanger, step number 27
must be changed from "OFF" to "ON". When the
air is routed through the geo-heat exchanger, the
Ubiflux+ display shows the text "EWT".
