Description
The CT6-P sensor is an external temperature (weather) sensor, designed to work with PLUM boiler controllers from the ecoMAX series. It is used to support combustion process control by selecting the appropriate heating curve. The sensor consists of a measuring element enclosed in a sealed housing with a gasket. The housing sealing level is IP65, which provides high protection of the measuring element against moisture, water and sun rays. Inside the sensor housing there is a terminal enabling connection of a cable that connects the external sensor with the controller. The sensor is adapted for external installation. The best place for installation is the coldest wall in a covered location.
