Today i purchased a a Honeywell DT90E Thermostat to replace a dial type Honeywell thermostat. I swopped then over without much hassle but the DT90E was showing a room temperature of 18 degrees when i was around 12 degrees. Is there some way of calibrating the room temperature.
The new thermostat seems to be cutting the boiler in and out with no apparent rhyme nor reason as the room temperature doesn't seem to be anywhere near the temperature set.
So could somebody give me in laymans terms how to set it up as the very basic instructions obviously aren't basic enough for me.
Thanks in advance Ben.
