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 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.
