Samsung Remote Room Temperature Sensor | MRW-TA | 12m Cable

The Samsung MRW-TA is a remote room temperature sensor (Samsung calls it an external room sensor) that takes the temperature reading away from the indoor unit or wall controller and places it where it is actually needed. Supplied with a 12 m extension cable, it lets you sense a secondary zone, or use the Samsung LCD purely as a controller while the sensor reads a single zone in a better location.

Each kit includes fixing screws, cable ties, wire joints, two connection adapters and an insulating seal kit, and the sensor can be surface mounted or flush mounted on a switch box, so it suits both retrofit and new-build installs.

Remove the cover by pressing the groove at the base of the case, then knock out the cable entry at the top. Loosen the terminal screws, fit the ring terminals of the extension cable and tighten fully so the two terminals cannot touch, then secure the cable with a cable tie with the knot inside the case. Do not cut the factory ring terminals, do not splice cables without a connector, and keep the cable away from power cables or sources of electrical noise. Make sure the sensor air vent is not blocked, then run the unit in heating or cooling to confirm normal operation.
