Check Dip Switches
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 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.
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.

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
Automated Demand Response
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
Skyport (setup step 50)
Set to ON to allow access to Skyport services or to OFF to not allow to Skyport services. (WiFi accessory is required). Visit Source1thermostats.com for more information.
Local API (setup step 51)
Set to ON to allow third-party software to interface with your thermostat. Typically used with home automation set-ups. (WiFi accessory is required).
ADR (setup step 52)
Controls whether you want the thermostat to possibly respond to signals from the utility provider. Select ON to allow this and to have steps 53-59 appear.
ADR Action (setup step 53)
Allows the user to determine what action is taken when the ADR event is received.
- Observe Setpoint Offsets – will offset the heat and cool setpoints by the amounts specified in setup steps 58 and 59
- Observe Static Setpoints – will set the heat and cool setpoints to the values specified in setup steps 56 and 57
Event Max Cool Setpoint (setup step 54)
Event Min Heat Setpoint (setup step 55)
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 even
Static Cool Setpoint (setup step 56)
Static Heat Setpoint (setup step 57)
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 58)
Heat Setpoint Offset (setup step 59)
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 -15 degrees while the cool setpoint can be automatically raised by 1 to 15 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 when an event is pending or active. For instance, when an ADR event has been sent to your thermostat, you might see ADR STARTS 8/14 at 2:00 pm to notify you of a pending event. Once active, you might see ADR STOPS 8/14 at 6:00pm. When an event is active, you can press any of COOLER, WARMER or MODE buttons, followed by the WARMER to opt out of the event.
