I know how to set the thermostat but the heaters dont seem to come on unless set to a high heat !!

SOURCE: Leviton Single Pole Switch with Pilot Light Model 277W Box

Depends on whether you want the pilot to glow when the circuit is live (the main light is on) or to glow when the circuit is off. (The switch can be used either way, and I have used this switch in both configurations at different places.)

The wiring diagram is on the inside of the box.

In indicates that if you want the pilot light to glow when the circuit is off, then you only need two wires (the live and the return, usually colored black and white, respectively). However, you also need a ground. The instructions say that you need the ground for safety (and probably legal code) reasons, but I suspect that, without the ground, the pilot light won't work in this configuration.

However, if you want the pilot light to glow when the circuit is on, you probably need a three wire configuration (plus the ground).

Hope this helps.

You cannot replace the switch with a switch/receptacle combo because there is no neutral wire. The black and white that you see are both used as hot wires. One is the Line and the other is the Load.

You have to install another 2 wire cable or replace the existing with a 3-wire cable. A 3-wire cable has a black, red, and white, plus the bare ground wire
