ECOTRONIC tech
Cod. 3540V010 - 07/2010 (Rev. 00)

EN
System 1 with 1 tank, 1 circulating pump and 3 probes
(Modulating circulating pump, calculation, no supplementary heating/no elimination of excess heat)
Switching on
Whenever the power to the regulator is switched on, the display will activate all the symbols for 2 seconds; whe-
reas, 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÷180°C, the symbol S3 will be lit;
temperature of Solar Collector Return NTC Sensor S4 with range 1÷125°C, the symbol S4 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.
• 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 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 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 modulation
When the Solar Circulating Pump is working and the Solar Circulating Pump Operation parameter (Installer
parameter, default equal to 0=On/Off ) is set to 1, the modulation algorithm is:
1. If the difference between the temperature of Solar Collector Sensor S3 and Solar Collector Return Sensor S4 is less
than or equal to the Minimum - Solar Circulating Pump Modulation temperature differential parameter value (Installer
parameter, default equal to 10°C), the Solar Circulating Pump works at speed 1 (Min. power, 40%). To signal this
mode, the symbol A will be lit.
2. If the difference between the temperature of Solar Collector Sensor S3 and the Solar Collector Return Sensor S4
is greater than the Minimum - Solar Circulating Pump Modulation temperature differential parameter value (Installer
parameter, default equal to 10°C), the Solar Circulating Pump works at speed 2 (55%). To signal this mode, the symbol
B will be lit.
3. If the difference between the temperature of Solar Collector Sensor S3 and Solar Collector Return Sensor S4 is greater
than the Minimum - Solar Circulating Pump Modulation temperature differential parameter value (Installer parameter,
default equal to 10°C) plus the Solar Circulating Pump Modulation temperature differential parameter value (Installer
parameter, default equal to 5°C), the Solar Circulating Pump works at speed 3 (70%). To signal this mode, the symbol
C will be lit.
4. If the difference between the temperature of Solar Collector Sensor S3 and Solar Collector Return Sensor S4 is greater
than the Minimum - Solar Circulating Pump Modulation temperature differential parameter value (Installer parameter,
default equal to 10°C) plus double the Solar Circulating Pump Modulation temperature differential parameter value
(Installer parameter, default equal to 5°C), the Solar Circulating Pump works at speed 4 (85%). To signal this mode,
the symbol D will be lit.
