Installation
STEP 1 TURN OFF POWER TO THE HVAC SYSTEM
STEP 2 DETERMINE WIRING CONFIGURATION
Use the Wire Labels and the following table to keep track of wire colors on the old thermostat or on the heat pump / furnace / air conditioner
| HP | NON-HP | Wire Color |
| R | R or RH | |
| — | RC | |
| C | ||
| Y or Y1 | ||
| Y2 | ||
| AUX | W or W1 | |
| O/B | W2 | |
| G | ||
| L | — | |
STEP 3 REMOVE OLD THERMOSTAT
Remove the old thermostat from the wall, taking care not to allow the wiring to fall inside the wall
STEP 4 INSTALL MOUNTING PLATE
If there is space on the wall that needs to be covered, insert the Wall Plate between the Mounting Plate and the wall, and mount both plates using the same screws. Make sure the wires run through the center opening
STEP 5 ATTACH WIRING
- Using the labels, match the wires to the appropriate terminal.
- For each wire, press the terminal button and fully insert the wire into the side hole.
- Release the terminal button to secure the wire.
- If you have RC and RH wires, remove the jumper betweeen RC and RJP.
- ST898ZBR works as a router and requires RH/RC and C-wire
STEP 6 CONNECT THE BATTERIES
- Pull the battery tab from the back of the thermostat to activate the batteries.
- If the C wire is connected, the thermostat will draw power from the AC connection and use the batteries as backup.
- Battery-only operation typically lasts 18 months.
- ST898ZBR works as a router and cannot run on batteries.
STEP 7 ATTACH THERMOSTAT TO MOUNTING PLATE
- After the initial configuration, the home screen will be displayed, and the thermostat is ready to be attached to the Mounting Plate.
- Align the connector pins and the plastic retention posts, then push the thermostat onto the Mounting Plate.
- Make sure the connector pins are not bent and that the thermostat is fully seated on the Mounting Plate
STEP 8 TURN POWER BACK ON TO THE HVAC SYSTEM
STEP 9 INITIAL CONFIGURATION
- After initial power-up, the thermostat will attempt to pair with a network for 10 minutes. You may need to initiate scanning for devices in your connected home system.
- Once paired, canceled with the Down button ( X ), or timed out, the device will ask for the following initial settings.
To move forward and back through the Settings menu and make any changes to the settings, the buttons function as follows:
