I installed two of these. I could not get the receiver to work until I reversed the wiring from the heater's pilot thermocouple to the TP TP/TH connectors, then it was fine. The instructions fail to mention until after you need to know it that the receiver must be reenergized each time you switch it to "remote" from "on" or "off". Tuning the receiver to respond to the transmitter is a fiddle (a tiny screw down a dark hole). The communication fails if the transmitter is too high off the floor. Do not bank on twenty feet. Installing the second went a little faster! Smarthome sent the wrong model by mistake, but were quick and helpful to correct this. Summary: if you have to have a wireless control go for it, if you just think it would be nice, it may not be worth the effort.
