What is an S1 and S2 wires on a Honeywell thermostat?

What is an S1 and S2 wires on a Honeywell thermostat?

S, S1, S2: These wires run directly outside and provide outdoor temperature information to the thermostat.

Is com 24V the same as C wire?

The c wire is an extra wire that can be used to provide a return path for continuous 24V power for any application. It’s normally used to provide a return path to power the thermostat. The “c” stands for common. It is often labeled as “c” on thermostat backplates.

What is the difference between RH and RC thermostat wires?

RC: The RC terminal is the 24-volt cooling power supply. RH: The RH terminal is the 24-volt heating power supply. (Note: The RC and RH terminals are jumpered together in a four-wire heat/cool system and a single-stage heat pump system but not in a five-wire heating/cooling system.)

Where do the wires go on a Honeywell 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.

Where does the blue wire go on a Honeywell thermostat?

Blue wires are for heat pumps. This wire connects to terminal B on your thermostat.

Does R wire go to RH or RC?

An R wire can go into a Nest Learning Thermostat’s Rc or Rh connector.

Does red wire go to R or RC?

If you have both an Rh (Red-heat for powering the heating) and an Rc (Red-cool for powering the cooling), then the R wire can be connected to either Rh or Rc. If you only have a single R wire, then it will only have an R connector, which is the connection you’ll use.

Is the RC wire the same as C?

Typically, the wires that provide the power (often called the “hot” wires) are labeled Rc (cooling) and Rh (heating). They provide a source of 24V power coming from the HVAC control board. Sometimes they are separate wires and require separate connections. Other times they are the same wire.

What are R and Rc wires on thermostat?

Rh stands for Red-Heat and Rc stands for Red-Cool. If you only have a single red wire the jumper between Rh and Rc are required for some heating and cooling hybrid systems depending on your thermostat.
