We have 2 Intelligent Controllers serving the underfloor heating under our large tiled kitchen floor. Both have been set to identical Custom programs (Period 1 with initial on at 7.00am and off at 9.00pm 7 days a week). However, one of the controllers doesn’t seem to conform to the custom program timings and operates continuously. This is irrespective of the temperature – for example with a Custom temp of 23 degrees the heating remains on at midnight when measured temp is 19 degrees. Is it possible taht the controller has been wired in such a way as to by-pass the program settings or could there be another explanation?

The following happens , when in automatic mode lets say you set in your programmed times for the heating to heat up to 25 degrees.

When the program time finishes it falls back in to which called 'SETBACK MODE' , this mode will cause it to a maintain a temperature that is 5 degrees lower then the programmed temperature. I.e 20 degrees.

It does this so when it comes into the programmed times the floor only has to increase by a temperature of 5 degrees. instead of going up by 10 degrees or more if the floor did not maintain a set temperature.
