Duramaxx HT-31-3 Radiator Thermostat Set of 3 Including Valve Adaptors

Wireless radiator thermostat to keep your home at a comfortable temperature; reduces heating costs up to 30%.

Preset temperature modes, various week programmes and freely programmable heat phases.

Includes three valve adaptors for installation with other radiator valves.

This programmable wireless radiator thermostat from Duramaxx is the perfect tool for keeping your home at a comfortable temperature and is an efficient money saver when it comes to heating costs.

A variety of preset week programmes (7 day programme, work days and weekends, workdays, Saturday and Sunday, etc.) allow for time-controlled and individual customisation of the room's temperature. The respective temperature settings are saved and can then be quickly and easily chosen again without having to re-program them. Thus, for example, after getting up in the morning you can set the desired temperature for the night or even the entire week. It's ideal for cosy hours during cold winters.

Various temperature modes (Normal, Comfort, as well as Eco and Anti-frost) and further handy functions make the thermostat a practical household helper. It also features frost protection, which prevents the radiator from freezing. Holiday mode allows you to set the temperature and keep it constant for up to 199 days and freely programmable heating phases allow you to satisfy your own temperature needs individually.

To install the thermostat, simply remove the old one and replace it with the new one. The required valve adaptors are included, so you don't have to spend any more money. The Duramaxx HTF-31-3 thermostatic head only requires three 1.5 V double A batteries.
