protection by dry, airtight and dust-proof packaging (plastic bag with desiccant and humidity indicators). The storage
site must be vibration-free, water-tight and a constant-temperature. In case of reshipment (above all over longer di-
stances), it must be checked whether the packaging is suitable for the form and route of transport. Damages due to
improper transportation, storage or putting into operation are not liable for warranty.
1.8

Area of application

These installation and operating instructions describe the Temperature Control System WHS 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.
Further binding information on the hydraulic unit can be found on the rating plate!
