Operation
System 4 "EAST WEST" with 1 tank, 2 circulating pumps and 4 probes
Switching on
Whenever the controller is powered, the display will activate all symbols for 2 seconds; whereas, in the following
5 seconds, the display will show the controller software version.
Standby mode
After the activation phase, in the absence of faults and/or higher priority demands, the controller goes on standby.
The following information will be displayed:
• Standby: hot water tank NTC sensor S2 temperature with range 1÷125°C, the symbol S2 will be lit up; solar collector
return NTC sensor S1 with range 1÷125°C, the symbol S1 will be lit up.
• Press the Info button for 1 second to display the solar collector A PT1000 sensor S3 temperature with range 1÷180°C,
the symbol S3 will be lit up; solar collector B PT1000 sensor S4 temperature with range 1÷180°C, the symbol S4 will
be lit up.
• Press the Info button for 1 second and the controller returns to standby.
operation
Solar Circulating Pump A activation
If the hot water tank sensor S2 temperature is less than the Tank maximum temperature parameter value (Installer
parameter, default 60°C) and the difference (positive) between the solar collector A sensor S3 temperature and the
hot water tank sensor S2 temperature is greater than or equal to the Activation temperature differential parameter
value (Installer parameter, default 6°C), the ECOTRONIC tech controller activates the solar circulating pump A.
To signal this mode, the solar circulating pump symbol will be lit up together with the symbol A.
Solar Circulating Pump A deactivation
If the hot water tank sensor S2 temperature is less than the Tank maximum temperature parameter value (Installer
parameter, default 60°C) and the difference (positive) between the solar collector A sensor S3 temperature and
the solar collector return sensor S1 temperature is less than or equal to the Deactivation temperature differential
parameter value (Installer parameter, default 4°C), the ECOTRONIC tech controller deactivates the solar
circulating pump A.
If the hot water tank sensor S2 temperature is greater than or equal to the Tank maximum temperature parameter
value (Installer parameter, default 60°C), the ECOTRONIC tech controller deactivates the solar circulating pump A.
To signal this mode, the solar circulating pump symbol will go off together with the symbol A.
Solar Circulating Pump B activation
If the hot water tank sensor S2 temperature is less than the Tank maximum temperature parameter value (Installer
parameter, default 60°C) and the difference (positive) between the solar collector B sensor S4 temperature and the
hot water tank sensor S2 temperature is greater than or equal to the Activation temperature differential parameter
value (Installer parameter, default 6°C), the ECOTRONIC tech controller activates the solar circulating pump B.
To signal this mode, the solar circulating pump symbol will be lit up together with the symbol B.
Solar Circulating Pump B deactivation
If the hot water tank sensor S2 temperature is less than the Tank maximum temperature parameter value (Installer
parameter, default 60°C) and the difference (positive) between the solar collector B sensor S4 temperature and
the solar collector return sensor S1 temperature is less than or equal to the Deactivation temperature differential
parameter value (Installer parameter, default 4°C), the ECOTRONIC tech controller deactivates the solar
circulating pump B.
If the hot water tank sensor S2 temperature is greater than or equal to the Tank maximum temperature parameter
value (Installer parameter, default 60°C), the ECOTRONIC tech controller deactivates the solar circulating pump B.
To signal this mode, the solar circulating pump symbol will go off together with the symbol B.
