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.

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

A. 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.

B. 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 53.

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:

1. Use the 4 wires as instructed in the“Making 4 Wires Work When 5 Wires Are Required” section on page 53, and note that the fan will only operate with a Heating or Cooling demand.

2. Pull new thermostat wire from the HVAC equipment to the thermostat so that there are at least 5 wires available.

3. Purchase and install a Venstar Add-A-Wire accessory.

C. 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.

Installation Instructions

Page 63

D. 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:

1. Use the available wires as instructed in the“Making 4 Wires Work When 5 Wires Are Required” section on page 53 and note that the fan will only operate with a Heating or Cooling demand.

2. Pull new thermostat wire from the HVAC equipment to the thermostat so that there are at least 5 wires available.

3. Purchase and install a Venstar Add-A-Wire accessory.

E. 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 (1

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:

1. Use the available wires as instructed in the“Making 5 Wires Work When 6 Wires Are Required” section on page 54 and note that the fan will only operate with a Heating or Cooling demand.

2. Pull new thermostat wire from the HVAC equipment to the thermostat so that there are at least 6 wires available.

3. Purchase and install a Venstar Add-A-Wire accessory.

Installation Instructions

Page 64

Making 4 Wires Work When 5 Wires Are Required

If you would like to install the Venstar thermostat using only 4 wires when 5 are required, follow the directions below. You will need a screwdriver along with a 3" long piece of thermostat wire to use as a jumper:

1. Make sure the power is off.

2. 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.

3. 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.

5. Place the “G wire” on terminal C.

6. Place one end of the 3" long jumper on terminal G.

7. 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.

8. 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.

Installation Instructions

Page 65

Making 5 Wires Work When 6 Wires Are Required

If you have a system that requires 6 wires, and you would like to install the Venstar thermostat using only 5 wires, follow the directions below. You will need a screwdriver along with a 3" long piece of thermostat wire to use as a jumper:

1. Make sure the power is off.

3. 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.

5. Place the “G wire” on terminal C.

6. Place one end of the 3" long jumper on terminal G.

7. 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.

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.

1. 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.

2. 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.
