Functions performed by the controller in the system:
- domestic hot water circulating pump and central heating
pump control system.
Tips for parameters programming:
F10=1 (container T1 and boiler T2 temp measurement)
F11=setting specifying the boiler temperature growth in
relation to the container temperature so that the domestic
hot water pump switches on, for example 8 °C
F12=DHW pump switching hysteresis, for example. 2 C
F15=given water temperature in the container. DHW pump
has a priority, so that only after reaching this setting, central
heating pump switches on, for example 60 °C
F16=OFF; F17=0.1; F21=0; F29=COOL ; F50=0 ; F51=0
F52=0 (when central heating pump switches on, domestic
hot water pump switches off)
