Dual Fuel On, Off, (Setup Step 59) – On – Tells the thermostat an outdoor temperature or a demand for third stage heat will be used to stop running the heat pump and only run 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.
Setup steps 61-63 will only appear if step 60 is set to ON.
Dual Fuel Changeover on Outdoor Temp (setup step 60) – ON: the change from Heat Pump to a fossil fuel source of heat will be based on outdoor temperature. (a local outdoor sensor is required for ‘ON’)
OFF: Heat Pump heating will be terminated when there is a demand for third stage heat and a switch to fossil fuel will be made.
Dual Fuel Balance Point (setup step 61) – (0˚ – 60˚ ) Specifies the outdoor temperature at which the heat pump will cease operating and a fossil fuel source of heat is used.
Fan Off Delay in Seconds* (Setup Step 62)
This feature allows the user to increase the cooling or electric strip heating efficiency of the system. The thermostat may be programmed to continue running the fan after a call for cooling or electric strip heating has been satisfied. This delay can be set for 0, 30, 60, 90, or 120 seconds. If set to 0, the fan will not run after a call for cooling or electric strip heating has been satisfied.
Fahrenheit or Celsius (Setup Step 63)
This feature allows the thermostat to display temperature in Fahrenheit or Celsius.
Aux Output Polarity* (Setup Step 64)
Open (Normally Open) means no voltage is sent to the AUX output when there is
no Air Patrol quality issue.
Closed (Normally Closed) means voltage is sent to the AUX output when there is
no Air Patrol quality issue.
Smart Recovery (Setup Step 65)
Smart Recovery turns on the heat or cool before the Morning start time to bring the room temperature to the Morning setpoint at the start of the Morning 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.
Dry Contact Operation* (Setup Steps 66-67)
Dry Contact Polarity (setup Step 66)
Open (Normally Open) – The dry contact is open until the connected device closes the circuit.
Closed (Normally Closed) – The dry contact is closed until the connected device opens the circuit.
Condensate Dry Contact Use (Setup Step 67)
CONDENSATE – If CONDENSATE is selected, when the dry contact is active, the thermostat will lockout the compressor terminal(s) and “CONDENSATE PAN OVERFLOW” will appear on the display.
VACATION – If VACATION is selected when the dry contact is active, the thermostat will be forced into AWAY/unoccupied settings.
FDD – If FDD is selected when the dry contact is active, the scrolling display will read
“Equipment fault”. This error message will disappear when the Dry Contact is idle.
Humidity Output Polarity* (Setup Step 68)
Open (Normally Open) means no voltage is sent to the HUM output when there is no demand for humidity.
Closed (Normally Closed) means voltage is sent to the HUM output when there is no demand for humidity.
Dehumidify Output Polarity* (Setup Step 69)
Open (Normally Open) means no voltage is sent to the DEHUM output when there is no demand to dehumidify.

Dehumidify Only With Cooling (Setup Step 70)
When set to ON, Dehumidify will only turn on with a 1st stage cooling demand.
When set to OFF, Dehumidify will turn on at any time that the room humidity exceeds the dehumidification setpoint.
ADR* (Setup Step 71)
Controls whether you want the thermostat to possibly respond to signals from the utility provider. Select ON to allow this and to have steps 72-78 appear. For these steps to have effect, your utility provider must have an applicable program in your service area in which Skyport participates and your thermostat is enrolled in the program. Check with your provider for enrollment details.
ADR Action* (Setup Step 72)
Observe Setpoint Offsets – will offset the heat and cool setpoints by the amounts specified in setup steps 77 and 78
Observe Static Setpoints – will set the heat and cool setpoints to the values specified in setup steps 75 and 76
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 at 4:15 to notify you of a pending event. Once active, you might see ADR STOPS at 5:30.If you have configured a threshold for cost of energy past which you want to trigger an event, you will see PRICING EVENT on the display. 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.
Event Max Cool Setpoint* (Setup Step 73)
Event Min Heat Setpoint* (Setup Step 74)
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 75)
Static Heat Setpoint* (Setup Step 76)
Specifies the setpoints that will come into use during an event when the ADR ACTION is set to OBSERVE STATIC SETPOINTS
Cool Setpoint Offset*

Vacation feature when connected to skyport. Skyport allows you to select future dates/times when your vacation will start and end. After sending that to the thermostat, no action is required at the thermostat. At the appropriate date/time, the thermostat will bring in your vacation settings and show VACATION on the scrolling display. The thermostat will return to prior settings when the vacation period ends. If you happen to return early while vacation is still active, button presses will be ignored except for the VACATION button. Press VACATION, followed by MODE to terminate the active vacation and return to normal operation. There is no provision for terminating vacation via Skyport. If you anticipate a variable return time, use the HOME/AWAY feature instead.

Use UP/DOWN to choose the mode to be used while away. Press MODE again and enter desired cool and heat setpoints. When done, press VACATION to return to the main screen. At midnight, the thermostat will bring in your vacation settings and show VACATION on the scrolling display. The thermostat will return to prior settings at midnight after the # of vacation days you specified have passed.
Emergency Heat
The Emergency Heat function is only available if your thermostat is set to control a Heat Pump.
To initiate the Emergency Heat feature, Press the EMERGENCY HEAT button. During Emergency Heat operation the thermostat will turn on the fan and auxiliary stages of heat when there is a demand for heat. The compressor will not be turned on for either heating or cooling. To exit Emergency Heat, press the EMERGENCY HEAT button.
Under normal circumstances it will not be necessary to adjust the calibration of the termperature or humidity sensors. If calibration is required, please contact a trainsed HVAC technician to correctly perform the folowing procedure.
Resetting the thermostat to the Factory Default Settings
(for default values see page 49, Advanced Setup Steps Table)
If, for any reason, you desire to return all the stored settings back to the factory default settings, follow the instructions below.

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.
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.
