Underfloor heating is best controlled with fully independent zone control. Basically, each room should have its own thermostat to control the air temperature. This allows you to balance the building to how you feel most comfortable living in it. Some rooms you may want warmer than others, i.e. lounges and bathrooms you may want to be much warmer than other rooms like kitchens or gyms.

Underfloor heating should not be left running all the time, but likewise should never be allowed to cool down by more than a few degrees. This balance between on and off is created by adding a time clock, and an override thermostat to stop the system cooling down by no more than a few degrees. This small drop in temperature, whilst off is often referred to as a setback. The time control and setback can be done by a separate time clock and setback thermostat, or alternatively via programmable thermostats which have fully programmable time and temperature settings up on them.
