This feature is available when the thermostat is connected to Skyport Cloud Services and may only be accessed through Skyport. This security feature is not accessible locally at the thermostat. When this setting is enabled; pressing the Override or Mode buttons on the thermostat will have no effect. This feature is often used in conjunction with setpoint limits.
These setup steps allow the user to monitor FAN runtimes and program service alerts. Service alerts appear on the display. If the thermostat is joined to a Skyport account, then the user may be alerted by Skyport Cloud Services when to change the filter.
Service Filter Runtime (setup steps 11-14)
Current Service Filter Runtime Hours (Setup Step 11)
– This counter keeps track of the number of hours of fan runtime in the Heating mode, Cooling mode, and in stand alone Fan operation. Press OVERRIDE to reset.
Current Service Filter Calendar Days (Setup Step 12)
– This counter displays the total number of calendar days that have elapsed since the counter was reset to help the user track Fan runtime. Press OVERRIDE to reset.
Set Service Filter Runtime Hours (Setup Step 13) –
This timer allows the user to specify the number of hours the fan will run before the “Replace Filter” alert will be displayed. Press COOLER continuously until OFF is displayed to disable this alert.
Set Service Filter Calendar Days (Setup Step 14) –
This timer allows the user to specify the number of calendar days that will elapse before the “Replace Filter” alert will be displayed. Press COOLER continuously until OFF is displayed to disable this feature.
Cycles Per Hour (setup step 15)
The Cycles Per Hour setting may limit the number of times per hour your HVAC unit may energize. For example, at a setting of 6 cycles per hour the HVAC unit will only be allowed to energize once every 10 minutes. The Cycles Per Hour limit may be overridden and reset by pressing the WARMER or COOLER buttons on the thermostat. Settings are No Limit, 2, 3, 4, 5, or 6 cycles per hour.
Compressor Minimum Off Minutes (setup step 16)
This feature allows the user to set a minimum off time for the compressor. Settings are 0 to 5 mins.
Minimum Heat/Cool Setpoint Difference (setup step 17)
This feature allows the user to set the minimum gap between Heat and Cool setpoints in AUTO mode. Select from 0 to 6 degrees.
Deadband Settings (setup steps 18 – 21)
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 (setup step 18)
Specifies the temperature difference between the room temperature and the desired setpoint before the first stage of heating or cooling is allowed to turn on. (1 – 6 degrees) For example, if the heat setpoint is 68˚ and the 1st Stage headband is set to 2 degrees, the room temperature will need to reach 66˚ before the heat turns on.
2nd Stage Deadband (setup step 19)
Specifies the additional temperature difference after the first stage turns on before the second stage is activated. (0˚ – 10˚)
Minutes Between 1st and 2nd Stage (setup step 20)
Specifies the minimum time (in minutes) after the first stage turns on before the second stage can turn on. (0 – 60)
Second Stage Turnoff Point (setup step 21)
Specifies whether second stage will turn off at first stage deadband or remain on until the room temperature demand is satisfied. Choose between Deadband or Setpoint.
Fan Off Delay in Seconds (setup step 22)
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.
Maximum Override Time setup step 23)
This feature limits the maximum override time when using the OVERRIDE button 1 – 4 hours.
Fahrenheit or Celsius (setup step 24)
This feature allows the thermostat to display temperature in Fahrenheit or Celsius.
Comfort Recovery (setup step 25)
With Comfort Recovery on, the thermostat will attempt to reach the OCCUPIED 1 setpoint temperature at the exact time programmed into the thermostat. Comfort Recovery, only works when the thermostat enters the OCCUPIED 1 from the UNOCCUPIED. For example, if OCCUPIED 1 is set for 6am at 72°F heating and 75°F cooling, the thermostat will turn the system on before 6am in an effort to bring the temperature to its correct setting at exactly 6am. The thermostat learns from experience, how early to turn on, so please allow 4-8 days after a program change or after initial installation to give Comfort Recovery time to adjust. If used with a heat pump, electric strip heat will be disabled while Comfort Recovery is active.
Pre-Occupancy Fan Purge (setup step 26)
When this feature is activated, the fan will turn on during an unoccupied period at a preset amount of time prior to Occupied 1. This preoccupancy fan purge timer may be set from zero to three hours, in 15 minute increments. Zero (0) means this feature is turned off.
Dry Contact Polarity (setup step 27)
Dry Contact Use (setup step 28)
Skyport Cloud Services (setup step 29)
If set to ON, the thermostat may communicate and receive data from the Skyport Cloud Services.
Local API (setup step 30)
Turning on the local API allows 3rd party software to interface with the thermostat such as a home automation system.
Available Modes (setup step 31)
This setup step may restrict the use of this thermostat to: Heat only or, Cool only, or Heat and Cool, or Auto changeover operation.
Show Clock (setup step 32)
This setup step will allow for removal of the clock and day of the week from the display. OFF removes the time and day from the display.
Locking/Unlocking the Keypad
To enter Time Period Programming screens, Press and hold MODE and UP until the scrolling prompt appears
The following steps determine when the Occupied period(s) will be active.
Upon pressing MODE after the above step; you will be prompted to Save and Exit or Copy this Occupied schedule to another day.
Deadband Operation
Controls up to two Heat and two Cool stages.
The 1st Stage of heat or cool is turned on when:
(A) The temperature spread from the setpoint is equal to or greater than: the setpoint plus the 1st stage deadband. This 1st stage headband is adjustable from 1-6 degrees and the default is two degrees.
The 2nd Stage of heat or cool is turned on when:
Turning on the Time Period Program
Pressing the MODE button should cycle through OFF, then the available modes (setup step #31) then Program ON. Note that this sequence may be restricted due to settings on the Skyport website. The thermostat can be configured to be nonprogrammable which will keep Program ON from appearing in the MODE sequence. The thermostat can also be configured to force the program to always be running so the MODE button will have no effect. This last setting is desirable in many commercial installations to keep users from changing to manual control and negating the energy savings possible when running the program.
Emergency Heat
Only available if you have a Heat Pump installed. To initiate the Emergency Heat feature, press the OVERRIDE button. While holding the OVERRIDE button press the UP button, for two seconds. The display will read ‘EM HEAT’ (Emergency Heat
