The 230V Slimline V4 Programmable Thermostat (White) is a versatile digital room controller. It functions as both a temperature monitor and an advanced programmer in one unit. Therefore, it serves as the perfect solution for managing multi-zone underfloor heating networks or standard radiator systems.
This line-voltage device connects directly to a standard 230V mains power supply. Consequently, it works as an ideal upgrade path for old, inefficient wall thermostats. You can easily adjust the internal software settings on-site to match your preference. Specifically, you can set the unit to run in non-programmable, 5/2-day, or full 7-day modes. Furthermore, you can switch the entire controller into a pure countdown timer mode. The hardware features a beautiful, clean white fascia that flush-mounts into a standard wall box. It measures just 15mm deep. Additionally, it includes a large, easy-to-read screen with an automatic white backlight that dims after 30 seconds.
This updated V4 model includes self-learning Optimum Start technology. This intelligent software calculates the exact heat-up time your property requires. Therefore, your home reaches the target temperature at the precise moment you want while minimising energy waste. It supports up to 4 custom temperature comfort levels per day. Finally, the motherboard includes a built-in air temperature sensor. It also accepts external connections for a remote floor probe or a thimble sensor. As a result, you can place the main thermostat safely outside high-humidity bathrooms while monitoring the room accurately.
