Setting the temperature
The desired (maximum) circulation temperature can be set on the thermostat controller.
WARNING
Risk of scalding from hot water!
In order to prevent scalding at the tap, the maximum hot
water temperature should not exceed 60 °C.
The thermostat controller is infinitely variable. When delivered, a flow temperature of
approx. 60 °C is pre-set. If, for example, the temperature at the circulation outlet is too
high, the supply temperature can be regulated down on the thermostat controller.
The following table gives an overview of the thermostat controller setting range:

Setting the pump revolution speed
In order to increase the energy efficiency of the circulation station, the revolution speed
of the pumps must be adapted to the system-specific conditions (pressure drop in the
pipework). See the controller manual as to how the revolution speed is adapted in the
controller.

Maintenance
The WHI circuload modules are low in maintenance. However, as part of the annual
inspection of the domestic water system, the following items should be
checked/observed:
•
Check all connections for leaks
•
Check the safety equipment
•
Perform a functional check and check the setting parameters
•
Plausibility check of the control parameters and nominal values
•
Check the heat exchanger for dirt and functioning
We recommend concluding a maintenance agreement.
