The TR2500W room sensor with a 10K NTC thermistor and operates with most Regulator Australia temperature controllers. The thermistor is installed in a special, vented enclosure that fits standard electrical mounting hardware and utilises a terminal block located on the rear and to ensure the thermistor is not influenced by any extraneous thermal activity in the wall space, the rear of each sensor is positively sealed. However considerable care should be taken when determining the location of the sensors so as to obtain a representative temperature for the room. The sensor should preferably be located on an internal wall; approximately 1500mm above the floor and care should be taken to avoid concealed water pipes, air ducts, and heat sources such as lights, computers etc, locations exposed to direct sunlight, or areas directly affected by the supply air stream. Corner locations should also be avoided because of the reduced air circulation. To average the temperature in a large zone multiple sensors can be connected to the controller to average the readings.

It operates with the TC5044 universal controller.
