Full Gauge Controls MICROSOL II plus is a differential temperature controller designed for solar heating systems. It automates the management of water temperature in thermal reservoirs and swimming pools, optimizing the use of solar energy.

  • It controls the water circulation pump based on the temperature difference between solar collectors and the reservoir or pool.
  • It features two solar backing outputs for electric, gas, or diesel heating or pool filtering.
  • Solar backing 1 can be scheduled with up to four daily events per day, and solar backing 2 can be configured to work in conjunction with the schedule.

AntifreezeS1toswitchonthepump
It allows setting the temperature for which the collectors start to ice. When the temperature at the
collectors (sensor 1) is too low (e.g. winter nighttime), the pump is switched on at regular intervals to
prevent the water from freezing and damaging the pipes. To deactivate this function, just decrement the
value until the message is displayed.
Antifreeze hysteresis
Minimum antifreeze time
Overheating temperature S1 to switch off the pump
Hysteresis for the antifreeze function to switch off the water circulation pump.
Minimum time for which the antifreeze function stays on even if the temperature at sensor 1 returns to
the normal value.
It allows setting the overheating temperature of the collectors to switch off the water circulation pump.
When the temperature at the collectors (sensor 1) is higher than an adjustable value, the pump is
switched off to prevent the overheated water from circulating through the pipes and damaging them (if
PVC pipes are used).

It allows setting the overheating temperature of the swimming pool to switch off the water circulation

It allows setting up the operating mode of the solar backing 1 output. The modes are:
Solar backing 1 working independently from solar backing 2
Solar backing 1 deactivated when solar backing 2 is activated
When this parameter has the value “1” and the solar backing 2 is activated the controller will display the
messageAA2. This option is used with solar heating systems containing gas (AUX1 output) and
electrical (AUX2 output) heating backups. In this condition when the controller activates the solar
backing 2 (electrical heating) it will alert the user that solar backing 1 (gas heating) is not working
properly.

User manual

Full Gauge Controls MICROSOL II plus is a differential temperature controller designed for solar heating systems. It automates the management of water temperature in thermal reservoirs and swimming pools, optimizing the use of solar energy.

  • It controls the water circulation pump based on the temperature difference between solar collectors and the reservoir or pool.
  • It features two solar backing outputs for electric, gas, or diesel heating or pool filtering.
  • Solar backing 1 can be scheduled with up to four daily events per day, and solar backing 2 can be configured to work in conjunction with the schedule.
