DHW heating in the instantaneous water system

TLP
Fig. 9 · Schematics of a system with instantaneous water heater
DHW heating in a system with an instantaneous water heater can be configured using sys-
tem Anl 5.
A hydraulic pressure switch signals the controller the beginning and end of DHW tapping.
When the pressure switch makes contact, the exchanger charging pump starts operation and
DHW temperature control at sensor VS2 is activated.
When the contact is open, the control valve shuts off the DHW circuit. The exchanger charg-
ing pump is deactivated with a certain delay.
Note!
Control of the exchanger charging pump is only possible if the Fault alarm output BA func-
tion has been deactivated.
