Tools and Hardware Reviews of Honeywell CG511A1000 Medium Thermostat Guard with Inner Shelf to Prevent Tampering

Customer Review: Works fairly well - needed modification for additional ventilation
Summary: 4 Stars

I bought this thermostat guard to cover our Honeywell RTH7500D Thermostat. It's very easy to install and fits the Thermostat perfectly. After installation, we noticed that the thermostat didn't detect changes in temperature very effectively, and therefore didn't turn on and off as expected.

For example, in the heating cycle, our thermostat was set to 70 degrees, and when covered by the thermostat guard would continue to detect a temperature of 70 degrees even when the room temperature dropped to 65 degrees.

Thinking this might result from insufficient air circulation around the thermostat, I cut one inch diameter holes in the thermostat guard - 2 in each side, 3 in top, and 2 in the bottom. With these additional "ventilation" holes, the thermostat turns on and off as it did before I put the guard on.

I've uploaded an image of the thermostat guard as installed with the holes cut in it. It is very difficult to fiddle with the thermostat settings through the holes, so cutting the holes hasn't affected the function of the thermostat guard.

So, if your thermostat doesn't work as expected after installing a thermostat guard, you can improve the situation by cutting a few holes in the guard - the acrylic/Lexan is thick enough to be cut without cracking.
