SS3 Backplate Extender Extended convenience
The aesthetically designed Reliable Controls SPACE-Sensor Temperature (SST3) series and SMART-Sensor (SS3) series can be mounted to an extender plate (SS3-EP) to avoid drilling holes in a wall. The backplate extender displaces the sensor off the wall so that it avoids a hole being made for connectors on the SST3 and SS3.
