4 How it works
4.1 Application
This circulator is suitable for drinking water only.
4.2 Functions
Timer function
Up to 3 switch-on/switch-off times can be programmed with the
timer function.
Works setting: 24 hours continuous operation
Temperature control system
The temperature control system keeps the water in the return
circuit at the set temperature. To achieve this, the pump is
switched on and off automatically.
This function ensures that
• from a set temperature of more than 55 °C, the danger of
germs forming in the circulation system is reduced
(DVGW requirement),
• lime deposits are reduced,
• the power consumption is reduced.
Works setting: temperature control system switched off.
Thermal disinfection
The boiler heats up periodically to approximately 70 °C for ther-
mal disinfection purposes. If the thermal disinfection function is
activated, the pump recognises this from an increase in temper-
ature to more than 68 °C. Irrespective of the timer function, it
then runs continuously for approximately 2 hours and then
switches off again.

Note:
The timer function and temperature control system
can be operated together. The timer takes priority. If both func-
tions are activated, there is no temperature control during the
switch-off period.
