Water supplementary heat register WH (Option)

A WH water/air supplementary heat register enables regulation of the supply air temperature. The flow and return of the heating system must be connected on site. The supplementary heat register enables a preset supply air temperature to be kept constant. The desired temperature is set using the controller.

Heating coil (option)

The frost protection with a 3 meter long capillary tube is installed on the heating coil. The cable of this thermostat should be connected to the reserved terminals in the switch cabinet after installation.

The cable on the reel is fed through a suitable cable gland. It is connected to the terminals 7-8 in the TB8 terminal block. The order of the cables does not matter.
