Area of application

– Intended use:
Operational reliability is only ensured when the hydraulic unit is used as intended. The hydraulic assembly WHSH HE 24
V (0-10 V) M is used to operate a heating circuit in connection with a Helios hot water heating register. It controls the
water flow in the heating register. The flow temperature to the heating register is controlled with a 3-way valve, which
is operated by an electric actuator 24 V (0-10V). The hydraulic unit WHSH HE 24 V (0-10 V) M enables the time and
space-saving connection of the heating register to the heating network.
All additional and/or other uses of the hydraulic unit are prohibited and considered improper. Intended use also includes
