Step 1. Honeywell RTH7500D Prepare for Installation
Check that the following items are included and that you have everything required for the installation:
- Two AA alkaline batteries
- No. 2 Phillips screwdriver and standard pocket screwdriver
- Drill
- Drill bit—use 3/16 in. for drywall; use 7/32 in. for plaster
- Level (optional)
- Hammer
- Pencil
- Electrical tape
Step 2. Follow Important Instructions
- Do not connect the wires to the new thermostat based on wire color because damage can occur to the heating and/or cooling system.
- These Installation Instructions explain later how to use the enclosed wire labels to correctly mark the wires connected to your old thermostat.
Step 3. Remove Old Thermostat
- Turn off power at the heating and/or cooling system or fuse/circuit breaker panel.
- Remove the cover from the old thermostat.
- Remove the old thermostat from the wall or wallplate. Do not remove the wires.
Step 4. Follow Special Instructions
- If you have two C and/or C1 wires connected to your old thermostat, do not connect them to your new thermostat.
- Disconnect the C and/or C1 wires. Make sure they do not touch each other or any other wires.
- Wrap the bare end of each C and/or C1 wire with electrical tape.
- If you have only one C and/or C1 wire connected to your old thermostat, connect this wire to C on the new thermostat.
- If you find any wires not connected to your old thermostat, do not connect them to your new thermostat.
- Wrap the end of the wires that are not connected with electrical tape.
Step 5. Label Old Thermostat Wires
- As you disconnect each wire, use the enclosed wire labels to wrap a wire label around each wire that matches the letter designation. Do not allow the wires to fall into the wall opening after the wires are disconnected.
- Remove any remaining part of the old thermostat from the wall. When connecting the wires to the new thermostat, refer to the wire labels. Do not connect wires to your new thermostat based on the color of the wire.
Step 6. Mount New Wallplate to Wall
- Separate the wallplate from the thermostat as shown.
- Pass the labeled wires through the wire hole on the wallplate.
- Position the wallplate on the wall with the arrow pointing up. Level the wallplate (for appearance only) and mark the two mounting holes with a pencil.
- Move the wallplate aside and drill holes at the locations marked on the wall. Drill 3/16 in. holes for drywall or 7/32 in. holes for plaster.
- Tap the wall anchors into the drilled holes until even with the wall surface.
- Position the wallplate over the wall anchors.
- Insert the mounting screws into the wall anchors. Check leveling, if desired, and tighten the mounting screws.
Step 7. Connect Wires to New Wallplate
- Match the labeled wires to the letter designations on the wallplate.
- Select the correct letter designations to follow for your system. If you have a standard heating and/or cooling system, use the CONVENTIONAL letter designations. If you have a heat pump system, use the HEAT PUMP letter designations to wire the new thermostat.
- If wires are to be connected to both Rc and R, loosen the Rc and R screw terminals and remove the metal jumper wire.
- If only one of the terminals, Rc or R, is to be connected, leave the metal jumper wire in place.
- Loosen the screw terminals. Insert the labeled wires into the holes on the side of the terminal block that match the letter designations. Tighten the screw terminals.
- If any of the labeled wires do not match the letter designations, see next page for wire connections.
- Compare letter designations on your old and new thermostats. Use the information below if you are wiring a CONVENTIONAL System. Use the information on page 20 if you are wiring a Heat Pump system.Do not connect more than one wire to each terminal. Be sure to read the notes referenced in the numbered triangles above. These numbered notes appear on the next page.
- Compare letter designations on your old and new thermostats. Use the information below if you are wiring a HEAT PUMP system.
- Push excess wire back into the wall opening. Keep wires in the shaded area.
Step 8. Install Batteries
- Install two fresh AA alkaline batteries on the back of the thermostat as marked on the thermostat.
- Remove tab labeled ìRemove during installationî in the lower right corner of the thermostat back.
Step 9. Attach New Thermostat to Wallplate
