The Low Profile Programmable Stat that's High in Value!

You will appreciate the SlimLine Programmable Thermostats that are designed to blend in with any decor and be barely noticeable on the wall. But don't let the low profile fool you. They are loaded with features, like self-prompting programming that more expensive thermostats only wish they had. All can be heat pump or heat cool. These thermostats will look so good and work so well that you will forget they're even there but won't forget that you installed them.

Standard Features:

  • Up to 3 configurable outputs for maximum flexibilityHeat pump compatible
  • Backlit, color-coded keys and legends
  • Large, easy to read backlit display
  • Configurable 7-day programmable or non-programmable
  • Configurable manual or auto-changeover
  • LED indicator glows green or red to indicate cooling or heating
  • Service filter and UV light indicators
  • Fahrenheit or Celsius display
  • Non-volatile memory
  • Keypad lock
  • Accepts the IR remote control accessory (Included)
  • Accepts the EZ Programmer accessory
  • Accepts the Call for Comfort telephone accessory
  • All of the standard features plus:
  • 1-day programmable with up to 4 time periods
  • Auto-changeover
  • 2-stage heat, 1-stage cool
  • For use with gas/electric, heat pump, electric & hydronic heat systems

Infrared remote operation allows for basic thermostat functions. Unique "warmer" and "cooler" commands make this extremely simple to use. 

How to add a Common wire on older 4-wire Thermostat Systems

This is a common problem when replacing a mechanical thermostat or a thermostat powered by batteries. These older thermostats require 4 wires, but newer more sophisticated thermostats require a 5th wire known as the Common wire to power the digital display. There are three ways to add the common wire to a four wire installation:

Note: Before starting, we recommend that you take a picture of the original wiring to the old thermostat as reference to help remember what terminal each thermostat wire was connected to.

Option #1: The easiest and least expensive option is to sacrifice independent control of your indoor fan.

  1. First, disconnect power from your heating and/or cooling system.

    Caution: if your heating and cooling system is powered during the thermostat installation process and you accidentally touch the R (red) power wire to the C (blue or brown) common wire, then you will permanently damage either the equipment fuse or the transformer in the equipment.

  2. After disconnecting power from your heating and/or cooling system, move the wire connected to the G terminal (typically green) that controls your indoor fan to the C terminal (common) on the thermostat.

  3. At your heating and cooling equipment repeat the same step and move the G terminal wire to the C terminal.

  4. At your heating and cooling equipment place a jumper wire from the Y equipment terminal to the G equipment terminal. This will allow the fan to turn on when the thermostat is calling for cooling or heating but it will not give you independent fan control from the thermostat.

  5. See diagram below for wiring instructions.

Option #2: The second way to add a wire is to install the Add-A-Wire accessory. Add-A-Wire allows two thermostat signals to be controlled from one thermostat wire. As above move the green wire from the G terminal to the C terminal on the thermostat and at your heating and cooling equipment. Now use the Yellow wire to carry the Add-A-Wire signal.

In applications where additional wiring cannot be run, the Add-A-Wire accessory can be used to add a wire to the thermostat.

  • Easy to install
  • Easier than running new wire
  • Allows 5 wire thermostats to use only 4 wires
  • Also allows 5 wires to work like 6 wires

Option #3: The final way to add a wire is to contact a licesned HVAC contractor. This contractor will be able to run the necessary number of thermostat wires from your heating and cooling system to your thermostat. Please visit the Distributors section of our website to find the nearest HVAC wholesale distributor to your location. You may contact any of these distributors for an HVAC contractor referral in your area.
