The Deadband is the number of degrees or minutes that the thermostat waits before it initiates the stages of heating or cooling. 1st Stage Deadband Specifies the minimum temperature difference between the room temperature and the desired setpoint before the first stage of heating or cooling is allowed to turn on. For example, if the heat setpoint is 68° and the 1st Stage deadband is set to 2 degrees, the room temperature will need to drop to 66 degrees before the heat turns on.

Number of degrees past 1st stage before 2nd stage turns on. (0 – 10 deg. F)

Number of minutes past 1st stage before 2nd stage turns on. (0 – 60 mins.) The 3rd and 4th stage deadband settings have the same adjustable steps as 2nd stage headband. Timers & Deadbands Installation Settings (Continued) (The 2nd stage deadband must also be met)

Turns on Free Cooling

Free Cooling shuts off above this outdoor temperature. (40 – 80 degrees

If you don’t have a compressor, set Mechanical Cooling to “NO”, Y1 will then be used to control the Free Cooling Damper(s) and Y2 will be disabled. If set to “YES”, mechanical (compressor) cooling will be controlled by the Y2 terminal. (See page 67 for wiring diagram Mechanical air conditioning is turned on with a 2nd stage demand for cooling and the Free Cooling, outdoor air damper is closed.

Turns on Heat Pump Lockout

Heat Pump will not run below this temp. (20 – 75 deg. F)

Turns on Aux Heat Lockout.

Aux Heat will not run above this temp. (0 – 75 deg. F) GAS/EL or HP dip switch must be set for HP and GAS or ELEC dip switch must be set for ELEC

This feature is for heat pump applications only. This will only appear if the GAS/EL or HP dip switch is set for HP and the GAS or ELEC dip switch is set for Gas. When Dual Fuel is ON, an outdoor temperature or, if Change With Outdoor is set to OFF a demand for third stage heat will be used to stop running the heat pump and switch to a fossil fuel source of heat. NOTE: Once the change to fossil fuel is made, the heat demand must finish with fossil fuel. Additional heat demands within 10 minutes will also use fossil fuel, regardless of outdoor temperature or stage demand.

• Dual Fuel – ON/OFF
• Changeover With Outdoor – ON/OFF
  • ON: Uses an outdoor sensor for changeover.
  • OFF: Uses a third stage heat demand for changeover.
• Adjust Balance Point

Installation Instructions

Remove and Replace the old thermostat
To install the thermostat properly, please follow these step by step instructions. If you are unsure about any of these steps, call a qualified technician for assistance

• Assemble tools: Flat blade screwdriver, wire cutters and wire strippers.
• Make sure your Heater/Air Conditioner is working properly before beginning installation of the thermostat.
• Carefully unpack the thermostat. Save the screws, any brackets, and instructions.
• Turn off the power to the Heating/Air Conditioning system at the main fuse panel. Most residential systems have a separate breaker for disconnecting power to the furnace.
• Remove the cover of the old thermostat. If it does not come off easily, check for screws.
• Loosen the screws holding the thermostat base or subbase to the wall and lift away.
• Disconnect the wires from the old thermostat. Tape the ends of the wires as you disconnect them, and mark them with the letter of the terminal for easy reconnection to the new thermostat.
• Additionally, we recommend taking a photo with your phone of the connections for future reference.
• Keep the old thermostat for reference purposes, until your new thermostat is functioning properly.

Wire Connections
If the terminal designations on your old thermostat do not match those on the new thermostat, refer to the chart below or the wiring diagrams that follow.

Before you go any further, determine what your existing wiring and equipment situation is

• If you have a Heating only system without Air Conditioning, the Venstar thermostat will require 3 wires: R (24Vac), C (24Vac) and W (Heat). Most systems that only have Heating use very simple thermostats that require 2 wires: the R (24Vac) and W (Heat). The Venstar thermostat requires 3 wires to the thermostat. In this case an Add-a-Wire accessory will not work and it will be necessary to install another wire for the C (24Vac) connection.
• If you have a single stage fossil fuel heater with air conditioning, the Venstar model will require 5 wires for independent fan control. They are R (24Vac), C (24Vac), W (Heat), Y (Cooling), and G (Fan). You may connect only 4 wires, as instructed in the “Making 4 Wires Work When 5 Wires Are Required” section on page 74. If there are only 4 wires present that are connected to the existing thermostat, there are at least 3 options available to connect the Venstar thermostat:
  • Use the 4 wires as instructed in the“Making 4 Wires Work
  • When 5 Wires Are Required” section on page 74, and note that the fan will only operate with a Heating or Cooling demand.
  • Pull new thermostat wire from the HVAC equipment to the thermostat so that there are at least 5 wires available.
  • Purchase and install a Venstar Add-A-Wire accessory.
• If you have a multi-stage HVAC system comprised of a fossil fuel heater with air conditioning, the Venstar thermostat will require the 5 wires mentioned above (R, C, W, Y, G) plus an additional wire for each additional stage of Heating or Cooling. You may reduce the 5 wire requirement to 4 if you give up independent fan control following the instruction in the “Making 4 Wires Work When 5 Wires Are Required” section on page 53, or use the optional Add-A-Wire accessory
• If you have a heat pump without aux heat, the Venstar model will require 5 wires: R (24Vac), C (24Vac), W1/O/B (Reversing Value), Y (1st Stage Compressor), and G (Fan). If you are short 1 wire, there are at least 3 options available to connect the Venstar thermostat
  • Use the available wires as instructed in the“Making 4 Wires
  • Work When 5 Wires Are Required” section on page 56 and note that the fan will only operate with a Heating or Cooling demand.
  • Pull new thermostat wire from the HVAC equipment to the thermostat so that there are at least 5 wires available.
  • Purchase and install a Venstar Add-A-Wire accessory.
• If you have a heat pump with aux heat, the Venstar model will require 6 wires: R (24Vac), C (24Vac), W1/O/B (Reversing Value), Y (1st Stage Compressor), W2 (Aux Heat), and G (Fan). If you are short 1 wire, there are at least 3 options available to connect the Venstar thermostat
  • Use the available wires as instructed in the“Making 5 Wires
  • Work When 6 Wires Are Required” section on page 57 and note that the fan will only operate with a Heating or Cooling demand.
  • Pull new thermostat wire from the HVAC equipment to the thermostat so that there are at least 6 wires available.
  • Purchase and install a Venstar Add-A-Wire accessory.

Making 4 Wires Work When 5 Wires Are Required

• Make sure the power is off.
• Label and disconnect wires at the thermostat. Please note the color and corresponding wire designator with each color. For example The R wire is red and the W wire is white and so on. You will need this information handy for the next step at the HVAC equipment.
• At the HVAC equipment end of the thermostat wires (usually at the furnace), locate the terminals that the wires are attached to.
• Remove the “G wire” from the terminal marked G. 5. Place the “G wire” on terminal C. 6. Place one end of the 3″ long jumper on terminal G.
• Place the other end of the 3″ long jumper on terminal Y. Please note that there will be more than 1 wire on terminal Y.
• When connecting the wires to the Venstar thermostat, note that the wire that was previously connected to the G terminal of the old thermostat will now be required to be connected to the C terminal on the
• Venstar thermostat. All other wires will be connected such that the connections on each end of the individual wires match terminal designations. For example: Connect the yellow wire on the thermostat end to the Y terminal on the thermostat. The yellow wire will be connected to the Y terminal on the HVAC equipment end also

Making 5 Wires Work When 6 Wires Are Required

• Make sure the power is off.
• Label and disconnect wires at the thermostat. Please note the color and corresponding wire designator with each color. For example The R wire is red and the W wire is white and so on. You will need this information handy for the next step at the HVAC equipment.
• At the HVAC equipment end of the thermostat wires (usually at the furnace), locate the terminals that the wires are attached to. 4. Remove the “G wire” from the terminal marked G.
• Place the “G wire” on terminal C.
• Place one end of the 3″ long jumper on terminal G.
• Place the other end of the 3″ long jumper on terminal Y. Please note that there will be more than 1 wire on terminal Y.
• When connecting the wires to the Venstar thermostat, note that the wire that was previously connected to the G terminal of the old thermostat will now be required to be connected to the C terminal on the
• Venstar thermostat. All other wires will be connected such that the connections on each end of the individual wires match terminal designations. For example: Connect the yellow wire on the thermostat end to the Y terminal on the thermostat. The yellow wire will be connected to the Y terminal on the HVAC equipment end also

The Venstar Backplate

NOTE: The backplate does not fully cover a full size vertical junction box. The ACC-WPLWH Venstar Wallplate or a single-gang, horizontally mounted junction box would be needed for that type of installation

To remove the thermostat backplate:
Using the Finger Pull Areas, pull the front housing away from the backplate

Explanation of Thermostat Dip Switches

Dip switches are located on the back of the thermostat

This dip switch configures the thermostat to control a conventional gas/electric system or a heat pump. If your system is anything other than a heat pump, leave this switch set for GAS/EL.* *For some commercial heat pumps, this switch may need to be set for GAS/EL. Consult the commercial heat pump literature.
When the GAS/EL or HP dip switch is configured for HP, this dip switch (O or B) must be set to control the appropriate reversing valve. If O is chosen, the W1/O/B terminal will energize in cooling. If B is chosen, the W1/O/B terminal will energize in heating

When GAS/EL or HP is set for GAS/EL:
This switch (GAS or ELEC) controls how the thermostat will control the Fan (G) terminal in heating mode. When GAS is chosen, the thermostat will not energize the Fan (G) terminal in heating. When ELEC is chosen the thermostat will energize the fan in heating.

When GAS/EL or HP is set for HP:
This switch (GAS or ELEC) defines the Aux Heat type. When GAS is chosen, the auxiliary heat will not be allowed to run during heat pump operation. When using a Dual Fuel system, set this switch for GAS. When ELEC is chosen, up to two stages of auxiliary strip heat will be allowed to run
