Electrical after heating element
An after-heating element is necessary if you want to control the supply air temperature.
The electrical after-heating element can be purchased for installation in the supply air duct. The required sensor, PCB board and
connectors for the 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
T7 temperature sensor is mounted at the air heater. T2 sensor must
be disconnected from the circuit board.
The T7 sensor should then be connected to where the T2 sensor was previously connected up.

ATTENTION
The heating element must be insulated with a fire retardant insulation material. The cover of the connection box, how-
ever, must not be insulated.
