Functions performed by the controller in the system:
–collector pump control
–central heating boiler circulating pump control system
Tips for parameters programming:
F10=1 (boiler T1 and collector T2 temp. measurement)
F11=temperature difference T2-T1 between the solar
collector and the boiler after reaching that, the collector's
pump switches on, for example 8 °C
F12=pump switching hysteresis, for example 2 C
F15=OFF
F16=In cloudy days, when solar energy is low, it is essential
to heat-up the boiler from the other source. This parameter
specifies the boiler temperature below which an external
heating source switches on, for example boiler circulating
pump. Setting, for example 40 °C.
F17=90min (external heating source switching delay)
F21=0; F29=COOL ; F50=0 ; F51=0 ; F52=0
