Does this work with a T-87 H/C

Does this work with a T-87 H/C
Asked by: bob
Hi Bob! Unfortunately, without a full model number of the thermostat, we are unable to advise if this will be compatible with your thermostat. If you have a T87 Round Heat/Cool system, the Thermostat Guard will not work with your thermostat.

How do u innstall it on a base board heater?

Asked by: Liz
Probably cant if the control is located on the heater, this is much too large. Maybe there is a smaller one that you can use double back tape to glue over the control knob.
