3.6. Tank heating with thermostatic pump start
The tank heating is used to maintain a minimum temperature in the tank. The pump circulates the
cold water while the tank heating controls the temperature in the system. We recommend a
hydraulic installation as shown in
Figure 4 . Any bypass valves must therefore always be installed
frost-free. In order for the heating to be active the chiller must not be disconnected from the power
supply. Even if the external release is deactivated (
Chapter 8.3 External release) , the pump remains
active.

3.7. Overflow valve for standby operation
The overflow valve option should be installed if there is a possibility of the application severely
reducing or completely preventing flow of the cold water while the machine is running. The internal
overflow valve ensures the minimum flow rate through the chiller and therefore prevents the pump
from switching off.
Figure 5 shows the position of the internal overflow valve.
