How do I wire my thermostat?

If you just have one wire, regardless if it's labeled RC, it will go into the R terminal, and the jumper connecting terminals R and RC will be in place. Some thermostats have a jumper switch, some have a metal staple, others may have a plug, and the jumper may also just be a wire connecting the two terminals.

Effectively there isn't a second RH wire, although there is an RH terminal. However, the heating still needs to be controlled, so a wire known as a jumper is connected between the RC and the RH terminals so that power gets to the heating control part of the thermostat. This wire is also known as the RH wire.

If you check the Honeywell thermostat ct31a1003 wiring diagram, you'll see that it requires only two wires. This is because it's a very basic thermostat designed only to control a heating system. If you have a system that both heats and cools your house, you need a more complex thermostat with more wire terminals, and if your system incorporates a heat pump, you need even more wire terminals.

Some thermostats will be supplied with a jumper wire or clip between the thermostat RH and RC terminal and will not provide a simple R terminal (such as the 3M-22 Filtrete). Connect the red wire t. ... 3-Wire SPDT Honeywell T87F Thermostat wiring diagram.

K: Honeywell wire saver modules combine the Y and G wires to form a single K wire that connects to the K terminal on some Honeywell thermostats. It’s used for systems that don’t provide a C wire but have a thermostat that requires one. S, S1, S2: These wires run directly outside and provide outdoor temperature information to the thermostat.

Green – The green wire connects to the fan. Orange – This wire connects to your heat pump (if you have one). Red – Now, there can be two separate wires for this. One is for cool and the other is for heat, hence the abbreviation “RH” and “RC”. Blue – This is your common or “C” wire.
