System 2A And 2B With 1 Tank, 1 Circulating Pump And 3 Probes; Switching On; Standby Mode; Operation - Ferroli 0XBM2CX0 Instructions Pour L'installation Et L'entretien

SYSTEM 2A AND 2B WITH 1 TANK, 1 CIRCULATING PUMP AND 3 PROBES

(No modulating circulating pump, No calculation, With supplementary heating) for
Diagram 2A
(No modulating circulating pump, No calculation, With elimination of excess heat)
for Diagram 2B

Switching on

Whenever the power to the regulator is switched on, the display will activate
all the symbols for 2 seconds; whereas, in the following 5 seconds, the
display will indicate the regulator software version.

Standby mode

After the switching on stage, if there are no faults and/or higher priority
demands, the regulator goes to Standby mode. Therefore the following
information will be displayed:
• Standby display: temperature of Solar Collector PT1000 Sensor S3 with range 1¸175°C,
the symbol S3 will be lit.
• Press the Info button for 1 second to display the temperature of Hot Water Tank NTC Sensor
S2 with range 1¸125°C (the symbol S2 will be lit), and the temperature of Upper Hot Water
Tank PT1000 Sensor S1 with range 1¸175°C (the symbol S1 will be lit).
• Press the Info button for 1 second and the regulator returns to Standby mode.

Operation

Solar Circulating Pump activation
If the temperature of Hot Water Tank Sensor S2 is lower than the Tank
max. temperature parameter value (Installer parameter, default value equal
to 60°C) and if the difference (positive) between the temperature of Solar
Collector Sensor S3 and the temperature of Hot Water Tank Sensor S2 is
greater than or equal to the Activation temperature differential parameter
value (Installer parameter, default value equal to 6°C) then the ECOTRONIC
tech regulator activates the Solar Circulating Pump.
To signal this mode, the Solar Circulating Pump symbol will be lit.
Solar Circulating Pump deactivation
If the temperature of Hot Water Tank Sensor S2 is lower than the Tank max.
temperature parameter value (Installer parameter, default value equal to 60°C)
and if the difference (positive) between the temperature of Solar Collector
Sensor S3 and the temperature of Hot Water Tank Sensor S2 is less than or
equal to the Deactivation temperature differential parameter value (Installer
parameter, default value equal to 4°C) then the ECOTRONIC tech regulator
deactivates the Solar Circulating Pump.
If the temperature of Hot Water Tank Sensor S2 is higher than or equal to
the Tank max. temperature parameter value (Installer parameter, default
value equal to 60°C) then the ECOTRONIC tech regulator deactivates the
Solar Circulating Pump.
To signal this mode, the Solar Circulating Pump symbol will be off.
Supplementary heating (thermostat function) Only for diagram 2A
(Only with Parameter P20=1 and with Parameter P14 > P13)
During normal operation, if the temperature of Upper Hot Water Tank Sensor
S1 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 CONTACT on the 11-pin connector); whereas if the temperature of
Upper Hot Water Tank Sensor S1 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 Supplementary Heating mode, the Contact symbol will be lit.
Elimination of excess heat (thermostat function) Only for diagram 2B
(Only with Parameter P20=1 and with Parameter P14 < P13)
During normal operation, if the temperature of Upper Hot Water Tank Sensor
S1 is higher than the Thermostat activation temperature parameter value
Multifunction Solar Column
(Installer parameter, default value equal to 40°C) then the ECOTRONIC
tech regulator activates the output Relay connected to terminals 13-14-15
(FREE CONTACT on the 11-pin connector); whereas if the temperature of
Upper Hot Water Tank Sensor S1 is lower 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 Supplementary Heating mode, the Contact symbol will be lit.
