I am having difficulty adjusting the temperature of my easypel boiler. Someone could explain:
The hysteresis, the compensation on the electronic box and the compensation on the thermostat of so.de interior.
Goods.
The hysteresis is the difference of T ° between the opening and closing of a dry contact. On a boiler, the difference of T ° of the heating body. Typically 10 ° on oil boilers. Thus a boiler set to cut at 60 ° only turns on again when it goes down to 50 °.
as you have a probe, the map will create a hysteresis by program.

There is a dispersion of the characteristics of the probes, they do not measure the real T °, there is an error. For example, the ambient probe measures 19 ° while it is 20 °, or the start probe measures 40 ° instead of 38 °. This error is a constant. The compensation corrects this error.
After that there is the compensation of the water law by the ambient thermostat, but I do not think that it is about that.
