Package includes: RT6 thermostat on base, thermostat cover, wiring labels, screws and wall anchors, Installation,

Operation and Application Guide

Tools required for installation: Drill with 3/16” bit, hammer, screwdriver

WARNING!:  Always turn off power at the main power supply before installing, cleaning, or removing 

•  This thermostat is for 24 VAC applications only; do not use on voltages over 30 VAC
•  All wiring must conform to local and national electrical and building codes
•  Do not use air conditioning when the outdoor temperature is below 50 degrees; this can damage your A/C system

and cause personal injuries

•  Use this thermostat only as described in this manual

1.  Turn off power to the heating and cooling system by removing the fuse or switching the appropriate circuit

breaker off.

2.  Remove cover of old thermostat. This should expose the wires.
3.  Label the existing wires with the enclosed wire labels before removing wires.
4.  After labeling wires, remove wires from wire terminals.
5.  Remove existing thermostat base from wall.
6.  Refer to the following section for instructions on how to install this thermostat.

IMPORTANT: Thermostat installation must conform to local and national building and electrical codes and 

Note: Mount the thermostat about five feet above the floor. Do not mount the thermostat on an outside wall, in 

1.  Turn off power to the heating and cooling system by removing the fuse or switching the appropriate circuit

breaker off.

2.  To remove cover, pull gently at the seam at the top.
3.  Put thermostat base against the wall where you plan to mount it (Be sure wires will feed through the wire

opening in the base of the thermostat).

4.  Mark the placement of the mounting holes.
5.  Set thermostat base and cover away from working area.
6.  Using a 3/16” drill bit, drill holes in the places you have marked for mounting.
7.  Use a hammer to tap supplied anchors in mounting holes.
8.  Align thermostat base with mounting holes and feed the control wires through slit in thermal intrusion barrier and

into wire opening.

9.  Use supplied screws to mount thermostat base to wall.
10.  Insert stripped, labeled wires in matching wire terminals.

CAUTION!: Be sure exposed portion of wires does not touch other wires.

11.  Gently tug wire to be sure of proper connection. Double check that each wire is connected to the proper

terminal.

12.  Turn on power to the system at the main service panel.
13.  Configure thermostat to match the type of system you have.
14.  Replace cover on thermostat by snapping it in place.
15.  Test thermostat operation as described in “Testing the Thermostat”.
