Functions of DHW heating

6.1

DHW heating in the storage tank system

Operation with a storage tank sensor SF1 (BE3 to ModBus I/O 1402-0328 (3))
The controller begins charging the storage tank when the water temperature measured at sen-
sor SF1 falls below Min. storage tank. The storage tank charging finishes when the water tem-
perature measured at the sensor SF1 has reached the limit in Max. storage tank.
The Flow temperature set point defines the set point at the flow sensor VFg.
Operation with two storage tank sensors SF1 (BE3 to ModBus I/O 1402-0328 (3)) and
SF2 (BE4 an ModBus I/O 1402-0328 (3))
The controller begins charging the storage tank when the water temperature measured at sen-
sor SF1 falls below Min. storage tank. The storage tank charging finishes when the water tem-
perature measured at the sensor SF2 has reached the limit in Max. storage tank.
The Flow temperature set point defines the set point at the flow sensor VFg.
Operation with storage tank thermostat (BE3 to ModBus I/O 1402-0328 (3))
The storage tank thermostat is connected at SF1 and switches the storage tank charging on and
off. The Flow temperature set point must still be defined.

6.1.1 Priority operation

In many systems, the allotted amount of water cannot meet DHW heating and heating operation
demands when they are required at the same time. As a result, the capacity required for DHW
heating needs to be taken from the heating system when great heating loads occur; and this, un-
til DHW heating has been concluded. For this purpose, the DHW heating can be given priority
by the set-back operation function. This is achieved by monitoring the temperature at storage
tank sensor SF1.
