1. Turn the system power OFF from the existing thermostat. Turn the power to the HVAC system OFF at the main power panel or at the furnace. 2. Remove the existing thermostat cover to access the wires from the wall. (Some thermostats may have multiple covers, screws or other locking devices that must be removed or disengaged.) 3. Locate, but do not disconnect the wires. (If wires are not visible, they may be connected to the back of the wall plate.
label the wire with this sticker: RH / R / VR / 4 24 Volt RH if your existing thermostat is marked...
4. Using the provided stickers, label each wire according to the chart. • If the terminals are not labeled, contact a qualified HVAC technician. • Note: Wire colors do not always comply with standards, so wire color should be ignored. Refer to the existing terminal designation for proper identification. • *If wires marked Y & C are both present, C may be a Common wire and should not be used. If you have a wire marked C, do not connect it to any terminal.

1. Loosen, but do not remove, the terminal screws. Note: A jumper wire has been provided, connecting the RC and RH terminals for systems that do not provide both an RH and RC wire. If you have both an RH and RC wire, remove this jumper. If you do not have both an RH and RC wire, leave the jumper in place. 2. Match and connect the wires from the wall to the terminals as shown. Wires should be inserted behind the black terminal shields. Tighten each screw after the connection has been made.
