The CXSIP is a surface-mount wall sensor for use with BN Thermic’s T16C touch screen thermostats. The sensor is supplied complete with a 3m lead and is rated IP65, making it suitable for installation in damp areas.

The most common application for the CXSIP is when a touch screen thermostat is controlling underfloor heating in a bathroom. In these circumstances the T16C thermostat is generally installed immediately outside the bathroom. The T16C is supplied with a floor sensor which must be installed under the bathroom floor and connected to the terminal block on the rear of the thermostat.

The additional use of the CXSIP sensor allows the thermostat to monitor the air temperature within the bathroom.
When a CXSIP sensor is wired to a T16C, the thermostat's built-in air sensor is bypassed.
