Re-regulating solar systems
A differential thermostat is most often used in conjunction with a solar system. Resetting its operation, it compares the temperature of the source, in this case the temperature in the collectors, with the temperature in the boiler or storage tank. If the source temperature is higher than the consumer temperature, it triggers the extraction of heat from the solar system. The differential thermostat also has functions to protect the collectors against overheating or freezing.
Heating of sanitary water
according to the timetable
In the old days, we used to heat water to a constant temperature, whether we needed it or not. Today, we realise that wasteful energy use is a cost, so we think about saving. Modern differential thermostats ensure maximum use of the available solar energy and the possibility to set individual heating programmes depending on when the user actually needs the water heated. The Seltron SGC differential thermostat also allows you to store excess energy in a storage tank. The stored energy is later used in the heating system and thus significantly increases its energy-saving performance.
Overview of the data
on the solar energy generated
Where a solar system is also used to heat domestic hot water, we would like to know about it, how much heating energy has been generated from this free renewable source. Seltron differential thermostats allow you to measure the energy produced and display the data in weekly, monthly and yearly graphs.
