Installing the thermostat
NOTE: For best RedLINK performance, mount thermostats at least 2 feet apart.
Separate wallplate from thermostat.
If your thermostat has a button along the top of the wallplate, press button on top and pull to remove the wallplate as shown. Updated models do not have this button. On those models pull evenly along the sides and bottom of the thermostat to separate it from the wallplate.
Mount wallplate as shown.
Mount new wallplate using screws and anchors included with the thermostat. Drill 3/16-in holes for drywall. Drill 7/32-in holes for plaster.
Connect power.
- Insert supplied AA alkaline batteries for primary or backup power
.
NOTE: When the thermostat is NOT used with the Equipment Interface Module or the TrueZONE Wireless Adapter, a C wire is required for RedLINK. - For 24VAC primary power, connect common side of transformer to C terminal.
Wire the thermostat. Is the thermostat wired directly to the equipment
- If the thermostat is wired directly to the equipment: a Refer to the table and wiring diagrams on the next page. b Turn on 24VAC NOW. 24VAC (C wire) is required to connect RedLINK accessories.
- If the thermostat is used with an Equipment Interface Module or TrueZONE Wireless Adapter, power the thermostat using Rc and C terminals or with batteries
NOTE: The relay outputs and inputs on the thermostat do not function when used with an Equipment Interface Module or TrueZONE Wireless Adapter.
With thermostat removed from sub-base, insert the coin cell battery.
NOTE: On some models the coin cell battery compartment slides out from the left side of the thermostat when viewing it from the back (not pictured).
Mount thermostat on wallplate.
NOTE: If your thermostat has hinges at the bottom of the wallplate as shown, insert the thermostat into the hinges, then push the top toward the wall until it snaps together. Updated models do not have hinges. On those models push evenly along the sides and bottom of the thermostat to connect it to the wallplate.

Remove factory installed jumper for two transformer systems.
The THP9045A1098 C-wire adaptor is used on heat/cool systems when you only have four wires at the thermostat and you would like the thermostat to be powered with a common wire. Use the Kterminal in place of the Y and G terminals on conventional or heat pump systems to provide control of the fan and the compressor through a single wire—the unused wire then becomes your common wire. See THP9045 instructions for more information.
POWERED HUMIDIFIER, DEHUMIDIFIER OR VENTILATOR
DEHUMIDIFICATION WITH LOW SPEED FAN
Wire the thermostat U1 terminal to the low speed fan for dehumidification control at the equipment as shown. The relay can be set to normally open or normally closed in the installer setup.
- Normally open, dry contacts
- Normally closed, dry contacts
NON-POWERED HUMIDIFIER, DEHUMIDIFIER OR VENTILATOR
CONNECTING A HEAT OR COOL STAGE TO U1
- U1 terminals are normally open dry contacts when set up for a stage of heating or cooling.
- You must install a field jumper if the stage of heating or cooling is powered by system transformer. Do NOT install a field jumper if the stage of heating has its own transformer. 1
