Description:
The universal thermostat is used as a stand-alone control unit for the components brine defroster / GHX regulating flap,
defroster heater or electric backup duct heater. It has two programmable and independent switching points (Temp 1 and
Temp 2) with adjustable hysteresis.
Depending on the application the temperature sensor is used as outside air sensor (for control of brine defroster /
motorised flap GHE), as exhaust air sensor (for frost protection heater) or as inlet air sensor (for after heater). The
relevant mode is set by using a DIP switch.
The control for the electrical consumer is performed by an electronic relay, parallel to this a potential-free changeover is
available. Releasing and inhibiting of the control can be performed by an external enabling contact. The programmed
temperature values as well as the temperature at the sensor are shown by a 7-segment display. The display is visible
through the transparent lid of the existing plastic humidor suitable housing.

Notes:
When using as control unit for the brine defroster/GHX regulating flap both temperature set points are
activated!
Temp 1 – setpoint assignment for intake air cooling – GHX regulating flap in position
