Tech ST-292 v2 Room Regulator: Adjusting Temperature Tolerance for Manual Mode Operation

Welcome,
I bought Tech room regulator ST-292 v2 yesterday, I can't deal with "manual mode".

Namely, I set a temperature of 22 degrees below which I want the stove to turn on, 22.4 in the room:
- if it falls to 21.8 degrees, nothing happens ...
- nothing happens also if the room is 21.2 degrees ...
- only when it falls to 21 degrees (or even less) then it sends a signal to the furnace and turns on.

I can see that the regulator has some tolerance set as 1 degree, how to make it having 22 set, when the temperature drops to 21.8 degrees, the oven will start?

In this controller you need to set the hysteresis to e.g. 0.5 degrees and then it will switch on the boiler after lowering the temperature to 21.5 degrees. There must be an instruction for the controller.

You are indeed right. Earlier I used Auraton there were no such problems.
Thank you for your help
