I have a 240 volt electric baseboard furnace and trying to update my thermostat. Old thermostat has two wires, bright thermostat has four wires, two of which are labeled nouns and other two labeled line. Could you explain how I line the new one? What is difference between rank and load? Thanks.
Your feeble thermostat closed the electrical circuit on one 'leg' of the 240V circuit. The other 'leg' must have be connected directly to the heater. With your latest thermostat, connect one 'line' wire to the chain coming from the breaker/fuse panel; connect one 'load' wire to the telecommunication going to the heater. Your other strip and load wires will not be required but marrette them individually to prevent any menace
You need to determine if the baseboard stove is controlled by line voltage (220V) or if nearby is a transformer stepping the voltage down.
If you determine this then you will know how to lead the stat. Most thermostats do not switch the line voltage (too dangerous).
Answers: If it's 240V., your space heater has two 'phase` wires.
Your outdated thermostat only open one of these
wires, interrupting the circuit, but leaving a live
line connected to the heater.
After this fried a 'DIY`er or two, it be required
that the thermostat interrupt both 'legs` of the circuit.
If the thermostat is part of the component, just chain both
incoming wires to the "line" side, and connect two
wires of equal size with 'hi temp` insulation, (THHN,
THHW), to the kiln from the "load" side.
