I have ceiling cable heat and want to replace the manual thermostats with programmable ones.

I want to replace a Singer Model 7165B, which has the following information on it:

18 Amp 277 VAC
22 Amp 125, 250 VAC
Double Line Break

I took one of the thermostats off the wall and it appears to have 4 wires connected to it, so I'm assuming I need a double pole programmable thermostat?

I've searched online but haven't found anything that can handle the Amps listed above

Any ideas on a programmable thermostat that would work with this setup?
