Just bought a house with the NOMA Thermostat-THM501
I followed the manual carefully and still couldn't set up the temperature.
Let say I set up P1, P2, P3 and P4 at 22C but the temperature won't stay on 22C but kept running and at one time the temperature was up to 27C.
Could someone please help and point out what did I do wrong.
Thanks in advance for your help.
