5.3. Central heating circuit circulating pump with an external alarm control system.

Functions performed by the controller in the system: 
–central heating circulating pump control 
–external acoustic signaller control
–system protection against overheating

Tips for parameters programming: 
F10=0 (T1 pipeline temperature measurement) 
F11=pump start temperature setting, for example 40 °C 
F12=pump switching hysteresis, for example 0.1 °C
F15=high temperature alarm in boiler, for example 85 °C
F16=OFF; F1 = 0.1; F21 = 0 
F29=COOLING (switching pump after reaching the 
temperature of the boiler) 
F50=0 or 2 (2 – if you used an external safety thermostat 
STB connected to the D1 input) 
F51=1 (sound signaller active) 
F52=0 (when the high temperature alarm occurs, the 
pump switches on to cool down the water in the boiler)

Functions performed by the controller in the system: 
–collector pump control
–external acoustic signaller control
–boiler protection against overheating 
Tips for parameters programming: 
F10=1 (boiler T1 and collector T2 temperature 
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=boiler overheating alarm, for example 85 °C 
F16=OFF; F17 = 0.1; F21 = 0, F29 = COOL; F50 = 0
F51=1 (sound signaller active) 
F52=0 (when the boiler overheating alarm occurs, pump is 
turned off so as not to collect a hot factor from the 
collector)

5.6. Fireplace with water jacket control system.

Functions performed by the controller in the system: 
- fireplace pump control 
- central heating circulating pump control.
Tips for parameters programming: 
F10=1 (boiler T1 and fireplace T2 temp. measurement)
F11=setting specifying the fireplace temperature growth in 
relation to the boiler temperature so that the fireplace pump 
switches on, for example 8 °C
F12=fireplace pump switching hysteresis, for example 2 °C 
F15=set water temperature in the boiler. Loading the 
domestic hot water boiler using the fireplace pump is a 
priority, so that only after reaching this setting, the 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 the central heating pump switches on, 
fireplace pump is switched off)
