TWWset reduces the current temperature at TPV or TO1 minus the
minimum temperature difference STE14 MIN TDIFF CHILLER. The fresh
water station then works at this reduced setpoint in order to reach
and maintain this value at the outlet on TWW. An active setpoint
reduction is indicated in the status of the fresh water station STA01
STATUS by means of an "8". If the setpoint reduction does not result in
a temperature drop on the primary side, further protective mecha-
nisms become active.
If the temperature on the primary side at TPV is lower than BAS15 MIN
TEMP HEAT SOURCE, the primary pump begins cycles. After a defined
switch-on time STE12 MIN.RUNTIME TPV PROTEC and the failure to
reach the minimum temperature at the TPV primary flow sensor, the
pump is blocked for a definable period of time STE13 MIN.OFFTIME TPV
PROTEC. This allows power to be supplied to the primary side once
again.
If the temperature in the tank (sensor TO1) is < BAS15 MIN TEMP HEAT
SOURCE, the primary pump is switched off. The cancellation of
charging is indicated in the status of the fresh water station STA01
STATUS by means of "11". If there is no sensor installed in the tank,
sensor TPV serves as the reference instead of sensor TO1.

The circulation pump is operated without interruption.
The circulation pump WWC can be operated in a temperature-con-
trolled manner. To this end, a minimum setpoint for the circulation
temperature [TBZ] is defined in the circulation return. SEK06 SETPOINT
