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)

–external acoustic signaller control
–system protection from overheating
Tips for parameters programming:
F10 = 0 (T1 boiler temperature measurement)
F11 = boiler temperature setting, for example 60 °C
F12 = pump switching hysteresis, for example 0.1 °C
F15 = high temperature alarm, for example 85 °C
F16 = OFF; F17 = 0.1; F21 = 0
F29 = HEATING (pump works until the temperature is
reached)
F50 = 0 or 2 (2 – if you used an external safety thermostat
STB connected to the D1 input)

–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)
