Information

Settings

Smart Recovery turns on the heat or cool before the Occupied start time to bring the room temperature to the Occupied setpoint at the start of the Occupied time period. Please allow 4-8 days for Smart Recovery time to adjust. When used with a heat pump, electric strip heat will be disabled while Smart Recovery is active.

Automated Demand Response

Touch Screen 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:
• 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.

Smart Recovery – ON
Smart Recovery turns on the heat or cool before the Occupied start time to bring the room temperature to the Occupied setpoint at the start of the Occupied time period. Please allow 4-8 days for Smart Recovery time to adjust. When used with a heat pump, electric strip heat will be disabled while Smart Recovery is active.

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.

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.

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 degr ees 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.

AUX output polarity

The AUX Output polarity may be set for Normally Open or Normally Closed to accommodate different types of humidification and dehumidification equipment.

The thermostat allows multiple wired or wireless sensor accessories to be connected/paired to the thermostat. Use this step to select which individual sensor or average of multiple sensors to be used as the control temperature for the space.

• Thermostat sensor only
• Wired sensor only
• Average all wireless sensors
• Average wired/thermostat
• Average wireless/thermostat
• Average all available sensors

Wireless Sensors
You may pair multiple Wi-Fi remote sensors to the thermostat to be used for temperature monitor or control. The sensors MUST be on the same Wi-Fi network as the thermostat. Skyport connectivity is not required. Start the pairing process by pressing the LINK button on the Wi-Fi sensor. This will cause it to send a message to the Wi-Fi router that will in turn broadcast that message. Any thermostat on the network should hear that broadcast and store information about the sensor. Use this section to Add New Sensor for use by the thermostat (pair) or Remove sensor to quit listening to a sensor (unpair). Multiple thermostats can pair to the same sensor (handy for outdoor sensor use) or pair to a group of sensors (average multiple sensors in a large space served by multiple units).

• Installation Settings
• Wired Sensor Use (remote)

The wired sensor may be used as follows:

• Use as outdoor sensor
• Use as remote sensor

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 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.
• If you have a smartphone handy, take a photo of the wiring for future reference.
• 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 re-connection to the new thermostat.
• 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.

Wire from the old thermostat terminal marked	Function	Install on the new thermostat connector marked
G or F	Fan	G
Y1, Y	Cooling	Y1
W1, W	Heating	W1/0/B
Rh, R, M, Vr, A	Power	R

W2	2nd Stage Heat	W2
Y2	2nd Stage Cooling	Y2
W3	3rd Stage Heat	W3
OUT –	Outdoor Sensor	SENSOR
OUT +	Outdoor Sensor	SENSOR

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 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.
• B. 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 on page 78.
  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” section on page 78, and note that the fan will only operate with a Heating or Cooling demand.
  • Pull 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.
• C. 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 instructions in the “Making 4 Wires Work When 5 Wires Are Required” section on page 78, or use the optional Add-A-Wire accessory.
• D. 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 Value), 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” section on page 78 and note that the fan will only operate with a Heating or Cooling demand.
  • Pull 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.
• E. 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 Value), 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” section on page 79 and note that the fan will only operate with a Heating or Cooling demand.
  • Pull 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.
