CAUTION Follow the Installation Instructions before proceeding. Set the thermostat mode to “OFF” prior to changing settings in setup or restoring Factory Defaults. FCC Compliance Statement This equipment has been tested and found to comply with the limits for an intentional radiator, pursuant to Part 15, subpart C of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.

Glossary of Terms Auto-Changeover: A mode in which the thermostat will turn on the heating or cooling based on room temperature demand. Cool Setpoint: The warmest temperature that the space should rise to before cooling is turned on (without regard to deadband). Deadband: The number of degrees the thermostat will wait, once a setpoint has been reached, before energizing heating or cooling. Differential: The forced temperature difference between the heat setpoint and the cool setpoint in Auto Mode.

Main Menu Buttons - Settings Automated Demand Response Overview 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.
Main Menu Buttons - Settings 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.
Main Menu Buttons - Settings 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.
Main Menu Buttons - Settings Selecting the Overview tab of the ADR page will cause a summary of ADR events to be displayed.
Main Menu Buttons - Settings 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. By selecting ADR – On, the user can participate in ADR events triggered by their utility, or price dependent events.
Main Menu Buttons - Settings 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.
Main Menu Buttons - Settings The user may limit the maximum Cooling Setpoint.
Main Menu Buttons - Settings The user may limit the minimum Heating Setpoint.
Main Menu Buttons - Settings The user may adjust the ADR Cooling ‘static’ Setpoint.
Main Menu Buttons - Settings The user may adjust the ADR Heating ‘static’ Setpoint.

Main Menu Buttons - Settings The user may adjust the ADR Heat offset. During an ADR event the heating setpoint will be adjusted by the amount of degrees configured in this step.
Main Menu Buttons - Settings When an ADR event is pending, and hasn’t started yet, there will be a yellow leaf on the top bar. This will be accompanied by associated text as shown below. During an ADR event there will be a green leaf on the top bar. This will be accompanied by associated text as shown below.
Main Menu Buttons - Settings If a Warmer or Cooler button is pressed during an active ADR event, then the user is presented with this opt-out screen. If a pricing triggered ADR event is enabled, there will be a green leaf on the top bar along with the actual cost of energy.

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.
Installation Instructions 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. Wire from the old thermostat Function terminal marked G or F Fan Install on the new thermostat connector marked G Y1, Y Cooling Y1 W1, W Heating W1/0/B Rh, R, M, Vr, A Power R C Common C O/B Rev.
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 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.
Installation Instructions 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 Valve), 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 Heating or Cooling demand. 2.
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 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.
Installation Instructions 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. 2. Label and disconnect wires at the thermostat. Please note the color and corresponding wire designator with each color.
Installation Instructions W1/O/B Y2 Y1 W2 W3/AUX 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 SENSOR To remove the thermostat backplate: Using the Finger Pull Areas, pull the front housing away from the backplate.
