HT-M Vertical White Underfloor Heating Thermostat
 
The HT-MA is Heatwell's manual thermostat.  The HT-MA does not need any programming.  All you have to do is turn on the thermostat to your desired temperature.
 
The HT-MA has a large dial to allow easy setting of temperature.  The dial also increases or decreases in clicks.  The HT-M is the perfect thermostat for those of us who have vision issues.
 
The HT-MA needs to be set on air sensor mode (not floor probe).  The HT-MA is suitable for new installs or as a replacement.
 
The HT-MA comes in four parts.  The thermostat, the dail, 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 TH-MA is to install.
 
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.
