This wireless electro-mechanical programmable room thermostat neatly minimises problems of compliance with Building Regulations Part L (Energy Conservation) and Part P (Electrical Safety). Combining the familiarity of a mechanical timer with the simplicity of a digital control, its as simple to fit as it is to use. Please note: We may supply the Potterton-branded version of this clock dependant on stock. The item is exactly the same but has a Potterton logo instead of Baxi. Please check with your local branch if you must have the Baxi-branded version.
