I wanted a black digital thermostat upgrade, but found the Coleman's a bit high.
The Honeywell RTH2300B
is programmable, has a lighted LCD panel, and after price match was $22.41 each at WM.
A SPDT switch
was used to provide high and low fan speeds.
These thermostats can be easily taken apart without tools for painting, and I used satin black Krylon Fusion which is made for plastic.
I wanted the switch mounted on the side, so some plastic had to be removed with a dremel cut off wheel to make room.
On the backing plate, the wire block was masked off to prevent paint from causing connection issues.
Red, White and Yellow wires from the RV are connected to R, W and Y terminals on the Thermostat.
The center terminal on the switch is connected to the G terminal, and the top and bottom terminals are connected to Green and Gray.
Just switch them if needed, so up on the switch is high fan speed on the A/C.
Blue is not used, this is not a 12V thermostat and must be powered by batteries.
Looking forward to the A/C's being better controlled this summer, and not needing to turn on a light to change the setting.
