Problem removing thermostat


I want to replace my old thermostats with a programmable model. Only problem is, I cannot figure out how to remove the old thermostat. Pictures are below. Where the wires are going in, there is no way I can see to remove that casing to get at the wire ends. Those screws on the box do not seem to loosen up anything when I remove them. Any ideas?

Problem removing thermostat


I do understand that you are in Canada and some things are different up there, but---that appears to me to be a "Humidistat" used to control a de-humidifier. But then again-the numbers do not appear correct for relative humidity. Could these numbers be referring to Celsius degree readings? And-I'm not familiar at all with any HVAC unit using just two wires for the control(s). On the back of the unit it does appear to have a screw with a square drive, this may be how to access the wire terminals.

Problem removing thermostat


Is this a thermostat that operates from line voltages? Does this control some form of electrical resistance heating?

Is that not a wirenut on the blue wire that I see in the photo. Are there wirenuts for both wires from the thermostat? If so, I suggest that this is where the wire is disconnected.

That looks like a line voltage t-stat. It is disconnected by removing the wire nuts that connect the leads inside the wall mounted electrical box. The wires going into the t-sat are part of the unit and are not designed to be user serviceable. Be careful and turn off the power, that will be 120 or 240 volts on the wires. Not sure where you find a programmable line voltage t-stat.

What is this t-stat controlling?

This thermostat controls the electric baseboard heater in the room. All of the thermostats in the house are like this. About 10 a dozen in all.
