Automated Demand Response
TouchScreen 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.

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 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.

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

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.

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.

The user may limit the maximum Cooling Setpoint.

The user may limit the minimum Heating Setpoint.

The user may adjust the ADR Cooling ‘static’ Setpoint.

The user may adjust the ADR Heating ‘static’ Setpoint.

The user may adjust the ADR Cool offset. During an ADR event, the cooling setpoint will be adjusted by the number of degrees configured in this step.

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.

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.

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. This will be accompanied by associated text as shown below

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.

Free Cooling requires additional dampers and ductwork to be installed. Additionally, the thermostat is wired in a different manner for this feature to function properly. Before enabling this feature, please make sure these steps are completed.

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.
Mechanical air conditioning is turned on with a 2nd stage demand for cooling and the Free Cooling, outdoor air damper is closed.

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 the changeover.
  • OFF: Uses a third-stage heat demand for the changeover.

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 the 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 Source 1 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 Source 1 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 Source 1 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. If there are only 4 wires present that are connected to the existing thermostat, there are at least 3 options available to connect the Source 1 thermostat:
  • Use the 4 wires as instructed in the“Making 4 Wires Work When 5 Wires Are Required” and note that the fan will only operate with a Heating or Cooling demand.
  • Pull the new thermostat wire from the HVAC equipment to the thermostat so that there are at least 5 wires available.
  • Purchase and install a Source 1 Add-A-Wire accessory.
• If you have a multi-stage HVAC system comprised of a fossil fuel heater with air conditioning, the Source 1 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”, or use the optional Add-A-Wire accessory.
• If you have a heat pump without aux heat, the Source 1 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 Source 1 thermostat:
  • Use the available wires as instructed in the“Making 4 Wires Work When 5 Wires Are Required” and note that the fan will only operate with a Heating or Cooling demand.
  • Pull the new thermostat wire from the HVAC equipment to the thermostat so that there are at least 5 wires available.
  • Purchase and install a Source 1 Add-A-Wire accessory.
• If you have a heat pump with aux heat, the Source 1 model will require 6 wires: R (24Vac), C (24Vac), W1/O/B (Reversing Valve), 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 Source 1 thermostat:
  • Use the available wires as instructed in the“Making 5 Wires Work When 6 Wires Are Required” and note that the fan will only operate with a Heating or Cooling demand.
  • Pull the new thermostat wire from the HVAC equipment to the thermostat so that there are at least 6 wires available.
  • Purchase and install a Source 1 Add-A-Wire accessory.

Making 4 Wires Work When 5 Wires Are Required

If you would like to install the Source 1 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 Source 1 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 Source 1 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

If you have a system that requires 6 wires, and you would like to install the Source 1 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. 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 Source 1 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 Source 1 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 Source 1 Thermostat Backplate

NOTE: The backplate does not fully cover a full-size vertical junction box. The S1-CTSPLATE Source 1 Wallplate or a single-gang, horizontally mounted junction box would be needed for that type of installation

IMPORTANT: This thermostat requires both R (24 VAC Return) and C (24 VAC Common) be connected to the backplate terminals.

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.

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.
