The HT4 Series has been designed to be very easy to program.  Many other models of thermostat make you feel as if you need a programming degree to operate.  Not the HT4 Series.  We have removed options that market research suggests that the majority of customers don't use. 

 

The HT4 Series Includes:

​

HT4 Vertical White

HT4 Vertical Black

wHT4 WIFI

HT4t Towel Rail

 

The HT4 Series has the option of selecting one or two programmable periods.  All programming of the thermostat is done while the unit is off.  While operating, only program mode or manual mode can be selected.  The HT4 Series is very easy to program and operate.

 

The HT4 Series can be used as a new install or as a replacement for an existing thermostat.  Heatwell uses the HT4 vertical white in all of our underfloor heating installs unless otherwise specified.

​

The HT4 Series comes in three parts. The thermostat, the mounting block, and the electrical block. The thermostat 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.
