Water after heating element
An after-heating element is necessary if you want to control the supply air temperature.
The water after-heating element can be purchased for installation in the supply air duct. The required sensors, Expansions PCB and
connectors to the ventilation unit are included.
Run the wires along the duct and through a grommet on the unit down to the circuit board. Connect the wires in accordance with the
wiring diagram.

ATTENTION
The T7 temperature sensor is mounted after the heating element. The T2 sensor must disconnected from the circuit
board, and the T7 sensor must then be connected to where T2 sensor was previously connected.
