HT4 Vertical White Underfloor Heating Thermostat
 
The HT4t is Heatwell's duel purpose thermostat.  Link your heated towel rails to your floor heating thermostat.  The HT4t will operate your heated towel rails with the same timing as the underfloor heating.  The HT4t does not allow for individual heating programs for the heated towel rails and the underfloor heating.
 
Unlike most of Heatwll's thermostats, the HT4t needs to be a new install.  The HT4t can not be linked to heated towel rails where the wall has already been finished.
 
The HT4t 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 thermostat is attached to the electrical block via an electrical ribbon.  The electrical block acts like a circuit breaker for an electrical surge.  The electrical block is the part likely to be affected by an electrical surge and can be replaced without having to buy another thermostat.
 
Parts are available.
