HT4 Thermostat Heatwell Heatwell NZ

HT4 Vertical White 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 funtions 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 TH4 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.
