1�9 Area of application
These installation and operating instructions describe the
Temperature Control System WHSH HE
(Complete set).
The set includes an electronic control unit WHSE that regulates the supply air or room temperature via 3-point-
output and it has an anti-freeze function.
The hydraulic assembly WHSH HE 24 V is used to operate a heating circuit in connection with Helios warm water heat-
er batteries. The flow temperature to the heater battery is regulated with the help of a 3-way-valve, which is operated
by an electrical actuator 24V. Only install within the building envelope in frost-free rooms > 5°C.
Further binding information on the hydraulic unit can be found on the rating plate!
