View Full Version : Daikin Altherma HT - how to set the room temperature to be more stabile

07-11-2012, 05:12 PM
I have the control unit in the room. It is set to 22C. The problem (for me) is, that the temperature must drop for 0,5C before system starts to heat, or it must be for 0,5C above the actual setting before the system stops to heat.

Can this hysteresis be smaller?

I am sure that you can adjust the hysteresis to be a larger value but I am not aware that you can reduce it below 0.5C. This would create short cycliing in the system, which could be counter productive.
