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.
• 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.
• If you have a smart phone 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 reconnection 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
C	Common	C
O/B	Rev. Valve	W1/O/B*
W2	2nd Stage Heat	W2
Ck1	Dry Contact Switch	DRY CONTACT
CKGND	Dry Contact Switch	DRY CONTACT

O/B is used if your system is a Heat Pump.

The Source 1 Thermostat Backplate

To remove the thermostat backplate: Gently separate the display from the base by pulling first from one side, then the other until the two pieces unsnap. A small screwdriver may be used, very carefully, to start seperating the two pieces.

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

Check Dip Switch

Ensure which switch is correct for your system. Dip switches are located on the back of the thermostat.

• 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.
  • 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 ELEC is chosen, one stage of auxiliary strip heat will be allowed to run.
• For Heat Pump Only
  • 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.
• 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

Automated Demand Response

Overview

Source 1 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.
• Selecting the Overview tab of the ADR page will cause a summary of ADR events to be displayed.
• ADR (setup step 29)
  Controls whether you want the thermostat to possibly respond to signals from the utility provider. Select ON to allow this and to have steps 30-36 appear.
• ADR Action (setup step 30)
  Allows the user to determine what action is taken when an ADR event is received.
• Observe Setpoint Offsets – will offset the heat and cool setpoints by the amounts specified in setup steps 35 and 36
• Observe Static Setpoints – will set the heat and cool setpoints to the values specified in setup steps 33 and 34
• Event Max Cool Setpoint (setup step 31)
• Event Min Heat Setpoint (setup step 32)
  Specifies the range of allowable setpoint adjustments to be enforced when any ADR signal has been received from the utility. Since you might be paying more for energy while an event is active, you can impose tighter limits on setpoint ranges that are only enforced during the event.
• Static Cool Setpoint (setup step 33)
• Static Heat Setpoint (setup step 34)
• Specifies the setpoints that will come into use during an event when the ADR ACTION is set to OBSERVE STATIC SETPOINTS.
• Cool Setpoint Offset (setup step 35)
• Heat Setpoint Offset (setup step 36)
• Specifies how much the current setpoints in effect prior to an event will be altered during an event when the ADR ACTION is set to OBSERVE SETPOINT OFFSETS. The heat setpoint can be automatically lowered by -1 to -10 degrees while the cool setpoint can be automatically raised by 1 to 10 degrees.
• DISPLAY INDICATIONS WHEN AN ADR EVENT IS HAPPENING
  After setting your desired values for use during an ADR event, the scrolling display will give a little information on when an event is pending or active. For instance, when an ADR event has been sent to your thermostat, you might see ADR STARTS at 4:15 to notify you of a pending event. Once active, you might see ADR STOPS at 5:30. When an event is active, you can press any of the COOLER, WARMER or MODE buttons, followed by the WARMER to opt out of the event.
