NOTICE! Do not disconnect the wires from the existing thermostat before reading these instructions. The wires must be labeled prior to removal to ensure proper reconnection
Uninstalling the existing unit
- 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. (Failure to turn off the power to the existing thermostat before removal could damage your system.)
- 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. See page 8 for common examples.)
- Locate, but do not disconnect the wires. (If wires are not visible, they may be connected to the back of the wall plate. Some models may have doors that open to expose the wires and mounting screws.)
wire labels
Using the provided stickers, label each wire according to the Wire Labels chart. (If the terminals are not labeled, contact a qualified HVAC technician.)
Note: Wire colors do not always comply with standards, so wire colors 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. This wire is used only for non-battery-powered thermostats.
Do not let the wires slip back into the wall during disconnection. You may want to secure the wires to the wall as you disconnect them. After all, wires are labeled, disconnect each wire and remove the existing wall plate. (Any unused wires should be capped with an approved electrical connector, such as electrical tape.)
installing the thermostat
- Remove the wall plate from the new thermostat by pressing the release tab on the bottom of the thermostat.
- Position the new wall plate on the wall and pull the labeled wires through the opening.
- If the existing holes do not match those on the Hunter wall plate, if there are no existing holes, visually level the wall plate and mark the wall for two holes.
- Remove the wall plate and drill two 3/16” holes where marked.
- Tap the plastic anchors into the holes until they are flush with the wall. (Do not use plastic anchors if you encounter a stud in the wall.)
- Reposition the wall plate on the wall, pulling the wires through the opening. Insert the mounting screws through the wall plate and into the anchors. Verify that the wall plate is visually level and securely tighten both screws.
