Step 3 - Beforeyougoanyfurther

Determine what your existing wiring and equipment situation is

before you disconnect any wires. If you are unsure of what type of

system you have, you may need to seek professional support.

A. IfyouhaveaHeating only systemwithoutAirConditioning,the

VenstarColorTouchthermostatwillrequire3wires.These3wires

are:R(24Vac),C(24Vac)andW(Heat).MostHeatingonlysystems

useverysimplethermostatsthatonlyrequire2wirestheR(24Vac)

andW(Heat).TheColorTouch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 ColorTouch 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 below, to the

ColorTouch but will give up independent fan control. The fan will

stilloperatewithaHeatingorCoolingdemand.

• 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 ColorTouch thermostat, they are:

1. Usethe4wiresasinstructedbelow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

(ACC-0410).

C. If you have a multi stage HVAC system comprised of a fossil fuel

heater with air conditioning the Venstar ColorTouch will require

the5wiresmentionedabove(R,C,W,Y,and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,orusetheoptionalaccessory;Add-A-Wire.

D. Ifyouhaveaheat pump without aux heat the Venstar ColorTouch

willrequire5wires:R(24Vac),C(24Vac),W1/O/B(reversingvalve),

Y(1ststagecompressor),andG(fan).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ColorTouch

thermostat, they are:

1. Usethe4wiresasinstructedbelow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(ACC-0410).

E. Ifyouhaveaheat pump with aux heat the Venstar ColorTouch will

require6wires:R(24Vac),C(24Vac),W1/O/B(reversingvalve),Y(1st

stagecompressor),W2(AuxHeat)andG(fan).Ifthereareonly5

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(ACC-0410).

MAKING 4 WIRES WORK when 5 are required

(without the optional Add-A-Wire accessory)

• If you have an all-electric heat system with air conditioning, this

method is not an option. You must either pull new wire or use the

optional Add-A-Wire accessory (ACC-0410).

• If you have a single stage fossil fuel heater with air conditioning,

and you would like install the Venstar ColorTouch using only 4 wires,

follow the directions below. You will need a screwdriver along with a

3” or 4” long piece of thermostat wire to use as a jumper.

takingcaretomakesurethateachwirefromtheHVACequipment

is connected to the same terminal designation on the ColorTouch

backplate.Forexample:the“Cwire”fromtheHVACequipment

shouldbeconnectedtothe“C”terminalofthethermostat.The

MAKING 5 WIRES WORK when 6 are required

(without the optional Add-A-Wire accessory)

• If you have an all-electric heat system with air conditioning, this

method is not an option. You must either pull new wire or use the

optional Add-A-Wire accessory (ACC-0410).

• If you have a multi stage system that requires 6 wires, and you
