Tools and Hardware Reviews of Honeywell RTH111B Vertical Digital Manual Thermostat
Customer Review: Inexpensive money-saving upgrade from a mercury switch
Summary: 5 Stars
I purchased this non-programmable thermostat to install in the portion of my two-family home that I rent out. I also purchased the similar Honeywell RTH221B Basic Programmable Thermostat programmable model for my own portion of the residence. Installation of both models is identical, and the main difference between the two is just the ability to set up a program of varying temperature changes based on your schedule. The non-programmable RTH111B has no clock feature. Just simple buttons to change the temperature up or down, and switches for a system fan (if applicable) and the HEAT-OFF-COOL selection.
The apartment that received the RTH111B is a simple heat-only gas powered baseboard system. The installation instructions were generally easy to follow, but I also found additional information on the Honeywell website explaining what each terminal actually was. It would have been useful for Honeywell to print this in the instructions. Summarized:
Rh : Heating power supply
Rc : Cooling power supply
W : Heating signal
Y : Cooling signal
G : Fan
The two heating systems in my home are both ONLY heat, and have a two-wire connection. The wiring looked about a hundred years old, but still worked perfectly once I connected the wires to the Rh and W terminals. Interesting to note that in both installations it did not seem to make a difference which of the two wires went to what terminal, so long as it was Rh and W. However in a more complicated system that includes more wires for cooling or a fan, I'd use the included labels to mark each wire and be certain it was connected properly.
I don't have any dollar amount savings to offer, but I can say that the temperature was MUCH more consistent in my apartment than it had been with the old round-style mercury switch which was prone to large temperature swings. There is no question in my mind that less fuel was used, and it's very likely that the two thermostats I purchased have already paid for themselves one month later.
