Solar Circulating Pump Anti-Shutdown Function; Boiler Integration On / Off Function - Ferroli 0XBM2CX0 Instructions Pour L'installation Et L'entretien

Multifunction Solar Column

Solar Circulating Pump Anti-shutdown function

After 24 hours of inactivity, the Solar Circulating Pump is activated for 3
seconds.

Boiler integration On / Off function

This function can be applied to all the Systems: on activating it, the possibility
of managing the thermostat function for supplementary heating or Elimina-
tion of excess heat is lost. The FREE CONTACT relay is for activating or
deactivating integration provided by the boiler.
ATTENTION: This function depends on the FREE CONTACT relay operation
mode parameter P20 value (Installer parameter, default value
equal to 1=Auto), which must be set to 3.
The following example gives System 2:
40
System 2: with 1 tank, 1 circulating pump and 3 probes.
(No modulating circulating pump, No calculation, With Boiler activa-
tion/deactivation).
- Assigning terminals and main diagram.

During normal operation, if the temperature of Hot Water Tank Sensor S2 is
lower than the Thermostat activation temperature parameter value (Installer
parameter, default value equal to 40°C) then the ECOTRONIC tech regulator
activates the output Relay connected to terminals 13-14-15 (FREE CON-
TACT on the 11-pin connector); whereas if the temperature of Hot Water
Tank Sensor S2 is higher than the Thermostat deactivation temperature
parameter value (Installer parameter, default value equal to 45°C) then
the ECOTRONIC tech regulator deactivates the output Relay connected to
terminals 13-14-15 (FREE CONTACT on the 11-pin connector).
The contact is voltage-free and with exchange contact: NC 14-15, NO
13-14.
To signal the boiler activation mode, the Contact symbol will be lit.
