The Heatmiser Slimline-B thermostat is a battery powered programmable thermostat designed to provide reliable heating control where mains wiring is not available or not desired. With its slim touchscreen design and intuitive programming, it offers a clean and practical solution for both new installations and retrofit projects.
Because the Slimline-B operates on batteries, it can be installed almost anywhere. As a result, it is particularly popular in renovation work, occupied properties, and projects where minimal disruption is important.
Battery Powered Programmable Heating Control
The Heatmiser Slimline-B removes the need for a permanent mains supply at the thermostat location. This makes it ideal for situations where running cables would be difficult, time-consuming, or costly. Consequently, installers can position the thermostat in the most suitable location for accurate temperature sensing.
Despite being battery powered, the Slimline-B delivers dependable performance and precise temperature control. It maintains stable heating schedules while offering the same ease of use as wired models.
Key Features of the Heatmiser Slimline-B
Battery Powered Operation
