I am replacing an old manual square d thermostat with a honeywell

Resolved Question:

I am replacing an old manual square d thermostat with a honeywell rlv430 thermostat. The old thermostat has 2 terminals that say line. There are 2 more terminals that are labeled load. How do I hook up the new honeywell thermostat with only 2 wires to the old wires?

You will twist one load and one line wire together with a wire nut. The other load will go to one wire and the remaining line to the other.


So load and line combined together...the remaining load and line go to the 2 wires.
