Question about Heating & Cooling
The thermostat on the unit is located in the lower right hand side of the unit behind the trim panel closest to the wall. Look for a yellow wire with a black rubber bulb on the end. It will have a few feet of extra wire tied up in the heater itself and allows you to raise it to get a better more accurate reading. To change it, you have to unplug it from the PC board and plug in the new one. You can not use a conventional thermostat on a Rinnai heater.
