Automated Demand Response

ColorTouch thermostats support the handling of specific signals from the utility provider. The utility generated signals carry pricing information and/or setback actions that alter the comfort settings of the thermostat in order to reduce energy usage on demand. This is known as Automated Demand Response or ADR for short. You must register to participate in a utility sponsored program, if offered by your local utility, to take advantage of this feature.

SKYPORT CLOUD SERVICES From the web application the user will select Thermostat Settings from the left column. Then the Demand Response

button is selected.

Overview

Main Menu Buttons -

The Demand Response conﬁguration page, shown below, is where the thermostat is conﬁgured to respond to the energy provider’s signals. It also sets operational parameters for the thermostat.

The left column of the ADR conﬁguration page allows or prevents access by the utility. Here communication with the utility and your thermostat may be turned On or Off.

The selected utility will provide a Program ID.

The Account ID would normally be the occupants utility account number.

Settings

Main Menu Buttons -

The right column of the ADR conﬁguration page is where the occupant adjusts the operational parameters for ADR. The utility may send up to 3 types of ADR signals to Skyport. These are:

1) Pricing for the cost of energy, 2) An Offset to the occupants’ comfort setpoints, and 3) a signal to enforce discrete or Static setpoints.

The Maximum Cooling Setpoint and Minimum Heating Setpoints for ADR events are adjusted here.

The Static Settings are applied when the utility sends a signal to allow the occupant to enforce their own discrete temperature settings during an ADR event.

The Offset Settings allow the utility to modify the Cool or Heat setpoints by the value set here during an ADR event.

A Price Trigger setting allows the occupant to set the maximum cost of energy threshold. When this threshold is exceeded the Price dependent action is enforced. This Price Trigger and Dependent action is enforced independent of an ADR event, as long as the utility sends ‘real-time’ pricing.

Settings

Main Menu Buttons - Settings

Selecting the Overview tab of the ADR page will cause a summary of ADR events to be displayed.

Automated Demand Response

Utility and Program setup must be done at the Skyport Cloud Services account. From the thermostat Home Screen, press the ‘Menu’ button, then select ‘Settings”.

From the above screen the ‘Automated Demand Response’ button is pressed.

Settings

By selecting ADR – On, the user can participate in ADR events triggered by their utility, or price dependent events.

Main Menu Buttons -

Selecting the ‘Price Dependent Action’ button allows the user to determine what action is taken when the price rises above the set threshold.

In the above example; if the price threshold is exceeded, the thermostat will invoke the ‘Offset Setpoints’ conﬁgured for an ADR event until the event is over.

Please note that the Threshold price may only be set in the Skyport Cloud Services account.

Selecting ‘Skip Event’ will take no action when the set price threshold is exceeded.

Installation Instructions

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 re quire 3 wires: R (24Vac), C (24Vac) and W (Heat). Most systems that only have He ating use ver y simple thermosta ts 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 nec essary to install another wire for the C (24Vac) connection.

B. If you have a singl e stage fossil fuel heate r 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” se ction on page 74.

If there ar e only 4 wires present that are c onnected to the existing

thermosta t, there are at least 3 options available to connect the Venstar thermostat:

1. Use the 4 wires as ins truc ted in the“Making 4 Wires Work When 5 Wires Are Required” se ction on page 74, and note that the fan w ill only operate with a Heating or Cooling demand.

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

3. Purchase and install a Vens tar Add-A-Wire ac ces sory.

C. If you have a multi -stage HVAC system com pris ed of a fossil fuel

heater with air conditioning, the Venstar thermosta t 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 re duce the 5 wire requirement to 4 if you give up independe nt fan control following the instruction in the “Making 4 W ires Wor k When 5 W ires Are Required” section on page 53, or use the optional Add-A-Wire accessory.

Installation Instructions

D. If you have a heat pump without aux heat, the Venstar model w ill

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 56 and note that the fan will only operate with a Hea ting or Cooling demand.

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

3. Purchase and install a Vens tar Add-A-Wire ac ces sory.

E. If you have a hea t pump w ith aux heat, the Venst ar model will require

6 wires: R (24Vac), C ( 24Vac) , W1/O/ B (Reversing Value), Y (1 Compr essor), 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 57 and note that the fan will only operate with a Hea ting or Cooling demand.

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

3. Purchase and install a Vens tar Add-A-Wire ac ces sory.

Installation Instructions

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 disconnec t wires at the thermos tat. Please note the color and corresponding w ire designator with e ach color. For example: The R wire is red and the W wire is white and so on. You will need this inf ormation handy for the next s tep at the HVAC equipment.

3. At the HVAC equipment end of the thermostat wires (usually at the furnace), loca te the terminals that the wires are attache d to.

4. Re move 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 b e more than 1 wire on terminal Y.

8. When connecting the wires to the Venstar thermostat, note that the wire that was previously connec ted to the G terminal of the old thermosta t will now be required to be conne cted to the C terminal on the Venstar thermostat. All other wires will be conne cted such that the conne ctions on eac h end of t he 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

Making 5 Wires Work When 6 Wires Are Required

If you have a system that require s 6 wires, and you would like to install the Venstar thermostat using only 5 wires, follow the directions be low. You will need a screwdriver along with a 3" long pie ce of thermos tat wire to use as a jumper:

Troubleshooting

• SYMPTOM: The thermostat touchscreen buttons are not responsive. CAUSE: The touchscreen is out of calibration. REMEDY: Remove the thermostat from the backplate. Push the

thermostat back onto the backplate, while keeping your ﬁnger pressed ﬁrmly against the center of the touchscreen, until the Calibration screen appears. Re-calibrate the touchscreen. See Touch Calibration section of

full user’s manual (page 19).

• SYMPTOM: The display is blank. CAUSE: Lack of proper power. REMEDY: Make sure the power is on to the HVAC and that you have 24vac between R & C.

• SYMPTOM: The air conditioning does not attempt to turn on. CAUSE: The cooling setpoint is set too high. REMEDY: Lower the cooling setpoint or lower the cooling set-point

limit. See Setpoint Limits (page 28).

• SYMPTOM: The heating does not attempt to turn on. CAUSE: The heating setpoint is set too low. REMEDY: Raise the heating setpoint or raise the heating set-point limit.

See Setpoint Limits (page 28).

• SYMPTOM: When controlling a residential heat pump, and asking for cooling, the heat comes on.

CAUSE: The thermostat reversing valve dip switch is set for “B”. REMEDY: Set the reversing valve jumper for “ O ”.

• SYMPTOM: When calling for cooling, both the heat and cool come on. CAUSE: The thermostat equipment dip switch is conﬁgured for “HP”

and the HVAC unit is a Gas/Electric. REMEDY: Set the equipment dip switch for “Gas”.

• SYMPTOM: Air handler control board fuse blows when thermostat is attached to backplate with power on, but does not blow until the thermostat is placed onto the backplate.

CAUSE: The Outdoor sensor and/or sensor wiring is shorted. REMEDY: Check/replace Outdoor sensor and/or sensor wiring.
