Not sure if this thread should post here or in Electrical but here goes.
I am wiring my shed and have decided to wire my two 1500W/120V radiant heaters to there own circuit with a line voltage thermostat. I was thinking about getting a honeywell CT410B because the price was right ($17 at sears). My question is how to connect the wires? The thermostat says it's 120/240 capable and has 4 wires - 2 black(L1 - T1) and 2 red(L2 - T2) for a positive off rather than just a lowest setting. I want to be able to turn the heat completely off when not in use. Since I am wiring 120 do I connect both line wires to the black from the circuit breaker and both load wires to the black from the heaters and twist the white wires together? Or should i just use 1 of the line and the same color load? or should I connect the black to black and white to red?
