The thermio essential BCP is an ErP class I thermostat that can be fastened to a cylinder or a pipe: The spring wire required for installation on a pipe, or the wire strap required for installation on a hot water cylinder, are both supplied by Graesslin as part of the contents. The water temperature is measured directly on the surface of the cylinder or pipe by means of a contact. When the thermostat detects a drop in temperature, the heating system is switched on and then switched off again when the target value is reached, unless the boiler is controlled by other products such as a timer, for example. ErP Class I control, giving 1% contribution to energy efficiency.
