The TPOne-B thermostat is the battery-powered version of the popular Danfoss TPOne range. It is designed for simple installation and everyday ease of use. The large backlit matrix display shows clear icons and text information, so the user always has an overview of the current settings and system status. Four touch comfort buttons allow quick programme adjustments without the need to navigate through the settings – just a single press is enough.

The default control algorithm is time-proportional control with load compensation (TPI/Chrono-Proportional), which, compared with simple on/off switching, ensures greater temperature comfort and improved boiler efficiency. Standard On/Off mode can also be selected as required.
