Function

Pump sets for return flow temperature maintenance with actuator
The pump set prevents the temperature in the boiler from falling under the dew point,
thus reducing contamination of the boiler.
The pump set is installed between the buffer tank and the boiler. The actuator is controlled
by an external controller. The actuator opens the 3-way valve as soon as the boiler circuit
has reached the set opening temperature. Then the pump can charge the tank.
Application ranges:
for heat sources requiring a return flow temperature maintenance,

as for example solid fuel boilers, wood firing and stove heating systems

NOTICE
Damage to property
The location of installation must be dry, load-carrying, frost-proof and protected against
ultraviolet radiation to prevent material damage to the installation. Mount the pump in
the return line to the boiler, as the high flow temperatures could damage the pump.
