HT4 Vertical Black Underfloor Heating Thermostat
 
The HT4 is a beautifully designed and functional underfloor heating thermostat.  The HT4 has been designed with ease of programming in mind.  We have stripped out some functions that are rarely used.  If you require a full function thermostat please look at the HT3
 
The HT4 comes in three parts.  The thermostat, the mounting block, and the electrical block. 
 
The electrical block is designed to be installed independently and does not need to be re-attached to the mounting block.  The electrician will love how easy the HT4 is to install.
 
All Heatwell thermostats come with a 2-year warranty.
