Wiring

Terminal Designations

• C 24 VAC Common Wire
• O Heat pump reversing valve energized in cooling
• B Heat pump reversing valve energized in heating
• W Heat relay
• RH 24 VAC power for heating
• RC 24 VAC power for cooling
• G Fan relay
• Y Compressor relay

Wiring Notes

• RH & RC Terminals
  In a single-transformer system, leave the metal jumper in place between the RH and RC. Remove the metal jumper in two-transformer systems.
• Heat Pump Systems (With NO Auxilary or Emergency Heat)
  If wiring to a heat pump, use a small piece of wire (not supplied) to connect terminals W (Heat relay) & Y (Compressor relay).
• Common wire
  The C (common wire) is optional when the thermostat is powered by batteries.
• Wire Specifications
  Use 18- to 22-gauge thermostat wire. Shielded wire is not required.
  Installation Tip: Do not overtighten terminal block screws, as this can damage the terminal block. A damaged terminal block can keep the thermostat from fitting on the subbase correctly or cause system operation issues. Max Torque = 6in/lbs.
