Installation Steps
Step 1: Turn Off Power
Turn off power to your air conditioning and heating system at the electrical service panel. This can be done via circuit breakers or by removing fuses from a fuse panel.
Diagram Description: Two diagrams illustrate power disconnection. The first shows a circuit breaker panel with multiple breakers, one labeled 'OFF' and highlighted. The second shows a fuse panel with multiple fuses. Icons indicate 'Power is ON' (⚡) and 'Power is OFF' (❌⚡).
Step 2: Remove Your Old Thermostat
Carefully remove your existing thermostat. Some models are secured with screws, while others may tilt upwards to detach.
Diagram Description: An illustration shows the back of an old thermostat with its mounting plate, displaying various wire terminals labeled W2, M1SC1, RS2, M1SC3, RS+5, RS1, RS GND on one side, and W1/O/B, Y1, G, M1SC2, CK1, CK GND, R, C on the other. Wires are connected to these terminals.
Step 3: Verify System Compatibility
Ensure the INSTEON Thermostat is compatible with your air conditioning system. Note: Heat pump and line voltage systems are incompatible with this thermostat.
Diagram Description: Two wiring scenarios are shown. The top diagram, marked with a checkmark (✔️), depicts a compatible wiring setup for the INSTEON Thermostat. The bottom diagram, marked with a cross (❌), illustrates an incompatible wiring configuration.
Step 4: Photograph and Label Wires
Take a clear picture of your current thermostat's wiring before disconnecting any wires. Use the included labels to mark each wire according to its terminal connection. Once labeled, remove the old thermostat's mounting plate.
Diagram Description: An image shows a smartphone displaying a photograph of thermostat wiring, alongside the old thermostat's mounting plate with wires still attached.
Step 5: Mount and Connect Wires
Mount the INSTEON Thermostat base to the wall and connect the labeled wires to the corresponding terminals on the thermostat base. Refer to the terminal labels for correct placement.
Diagram Description: A detailed view shows the INSTEON Thermostat's wire terminals. The terminals are labeled: 24COM, 24R, W1, W2, G, Y1, Y2. A close-up highlights the connections. A note indicates that 'Wire color may vary'.
Step 6: Power Up and Calibration
Close the thermostat cover. Return to your electrical service panel and turn the power back on to your HVAC system. Your INSTEON Thermostat will calibrate automatically and will then be ready for use.
