HT3 Series
The HT3 is Heatwell's full function underfloor heating thermostat. The HT3 can be programmed to operate 7 days, 5 + 2 days or a single day. The thermostat can be operated in program, manual, or manual over-ride modes. The HT3 is easy to program and operate.
The HT3 has been the main stay for Heatwell for several years, and has been proven to be a reliable option for new installs and thermostat replacements. The HT3 comes in vertical or horizontal, and in black or white.

HT4 Series
Heatwell's HT4 has been designed with simplicity of use in mind. Market research has suggested that many functions in modern underfloor heating thermostats are not being used and are not required. If you want a thermostat that operates the same way every day, has one or two possible programming periods, and can be operated like a manual thermostat, then the HT4 is for you!
The HT4 series has a WIFI option (using a smart phone app) and a Duel Function option (can operate both underfloor heating and heated towel rails). The HT4 can be used in new installs and as a replacement thermostat (with the exception of the duel function model).

HT5 Series
The HT5 is the simplest to program touch screen thermostat on the market. The HT5 allows for one programmed period, and can also be operated manually. The HT5 comes with a touch screen and is one step better than a manual thermostat in looks and design.
Programming is extremely easy to program and use. There are only four programming options required (time / maximum temperature / program time on / program timing off) . All programming is done with the unit off. Only selecting program or manual mode can be done while the unit is operating.

HT-M
The HT-M is our manual model. No fiddly touch screens or programming required! Turn the unit on and off to the temperature you desire with a twist of a knob. The HT-M is the perfect thermostat for users who only want to turn the underfloor heating on or off
The HT-M comes with an LCD light that shows red when the unit is on standby, and green when the unit is heating. The twist knob is large and is easy to grip. Using the twist knob, the selected temperature clicks into place.
