4.1 Application
The pump is intended for pumping drinking or process water in a
circulation system.
4.2 Functions
timer function.
Works setting: 24 hours continuous operation
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.
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.
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.
