SER65093 - Thermostat

Product Description

The recessed, mains-powered connected wall thermostat lets you control one or more heating elements (radiators, boiler, heat pump, valves, pilot wire…). It includes an internal temperature sensor (and can use a remote sensor), receives weekly programs configured from the mobile app, and automatically sends heating setpoints (in °C or pilot-wire modes) based on the time, the chosen program and the ambient temperature.

The user can also manually control the temperature or create temporary overrides, locally (+/− buttons) or remotely via the app.
