Glossary of Terms Auto-Changeover: A mode in which the thermostat will turn on the heating or cooling based on room temperature demand. Cool Setpoint: The warmest temperature that the space should rise to before cooling is turned on (without regard to deadband). Deadband: The number of degrees the thermostat will wait, once a setpoint has been reached, before energizing heating or cooling. Differential: The forced temperature difference between the heat setpoint and the cool setpoint.

Connect to Wi-Fi Overview At minimum the first 3 tasks below must be completed to access your thermostat remotely from a browser. The 4th step is optional (highly recommended) and only is needed to access your thermostat(s) from a mobile device. These steps are: 1. Successful connection to a local Wi-Fi Access Point with internet access. 2. Confirm receipt of a Skyport generated verification email (this only occurs once during the Skyport account setup). 3.
Connect to Wi-Fi Overview Wi-Fi Setup The IEC Configurator App is needed to configure the Wi-Fi Settings of this thermostat • Download the IEC Configurator App from your mobile device’s App Store. ICON • Open the IEC Configurator App - Choose the thermostat by sliding the thermostat pictures at the top of the apps’ display to the left until you see a picture of the thermostat. - Press and hold the FAN button of the thermostat for approximately 5 seconds to enter Wi-Fi setup screens.
Connect to Wi-Fi Overview Join a Thermostat to Skyport If the thermostat is connected to the local Wi-Fi access point but not yet joined to an existing Skyport account, you may join the thermostat to the account by doing the following: 1. 2. 3. 4. 5. 6. 7. 8. Log in to your Skyport account. Select the “Location” you want to add a thermostat into. Select the “Thermostat tab”. Select “+ Add thermostat”. A screen will ‘pop-up’ asking for a six digit code. Press the FAN button on the thermostat for 5 seconds.

If the FAN is not on the display, then the FAN is in Auto mode and will run only when necessary to heat or cool. 8 Locked icon Indicates the thermostat’s control buttons have been locked. 9 Override icon Indicates OVERRIDE is enabled.
Basic Operation Selecting Your Desired Temperature (adjusting the setpoints) Auto-Changeover Mode Pressing the WARMER or COOLER buttons in Auto mode will adjust both the heat and cool setpoints simultaneously. To adjust the heat and cool setpoints individually, choose HEAT mode to adjust the heat setpoint, and COOL mode to adjust the cool setpoint, then return to AUTO mode.
Basic Operation Using the FAN button for Fan Operation Press Press Press Press FAN FAN FAN FAN low speed medium speed high speed auto FAN Note: When the thermostat is placed in OFF with the MODE button the fan will not operate, unless Setup Step #18 is set to ON (page 19). Using the FAN button for OVERRIDE OPERATION Note: Override operation may only be used when the thermostat is running a time period schedule/program.

User Setup Setting the Clock and Day (setup steps 1 & 2) When your thermostat is connected to Skyport Cloud Services, the time and day of the week are controlled by Skyport. There is no local adjustment, Skyport also adjusts the time for Daylight Savings Time as well. To set the time and day when not connected to Skyport; enter the setup screens by pressing the MODE button and simultaneously pressing the FAN button for 5 seconds. Setup step 1 adjusts the clock.
User Setup: Backlight Operation Programmable (setup step 4) When the very simplest operation is desired, this thermostat may be configured to be nonprogrammable, with or without Auto-Changeover. If “NO” is selected, the thermostat will lockout the Program On screen; only the Off, Heat, Cool and Auto screens may be accessed by pressing the MODE button. Select “YES” if you would like your thermostat to be programmable, then the Program mode will be accessible through the use of the MODE button.
User Setup: Number of Pipes 2 or 4 Pipe System (setup step 9) Select Fan Coil System type: • 2 Pipe Fan Coil System, or • 4 pipe Fan Coil System.
User Setup: Deadband & Setpoint Limits Deadband 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 11) 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.
Installer Setup Setpoint Limits (setup step 13) When this feature is set to ON, the Heat and Cool Setpoints may be restricted to preset levels in Setup Steps 14 and 15. Maximum Heat Setpoint (setup step 14) Minimum Cool Setpoint (setup step 15) Lock MODE Buttons 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.
Installer Setup Maximum Override Time (setup step 16) This feature limits the maximum override time when using the OVERRIDE button 1 - 4 hours. Fahrenheit or Celsius (setup step 17) This feature allows the thermostat to display temperature in Fahrenheit or Celsius. Fan Auto Operation (setup step 18) ON = Continuous low speed fan OFF = Only energize with a heating or cooling cycle This step is useful when using a duct sensor to keep airflow for the sensor.
Installer Setup Control to Sensor (setup step 21) Select LOCAL to control to the temperature sensor inside the thermostat. Select REMOTE to control to a temperature sensor connected to the RS & R terminals of the thermostat backplate. Pre-Occupancy Fan Purge (setup step 22) 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.
Installer Setup Hot Water Valve Type (setup step 23) NORMAL CLOSED = Usual setting, hot water valve does not allow water flow when unpowered NORMAL OPEN = Hot water valve allows water flow when unpowered Options, NORMALLY OPEN and NORMALLY CLOSED, default = NORMALLY CLOSED. Chilled Water Valve Type (setup step 24) NORMAL CLOSED = Usual setting, chilled water valve does not allow water flow when unpowered. NORMAL OPEN = Chilled water valve allows waterflow when unpowered.
Dry Contact Operation Dry Contact Polarity (setup step 25) ‘Idle’ Dry Contact ‘Active’ Dry Contact ‘Idle’ Dry Contact Dry Contact Open (Normally Open) - The dry contact is open until the connected device closes the circuit. ‘Active’ ‘Idle’ Dry Contact Closed (Normally Closed) - The dry contact is closed until the connected device opens the circuit.
Installer Setup Skyport Cloud Services (setup step 27) If set to ON, the thermostat may communicate and receive data from the Skyport Cloud Services. Local API (setup step 28) Turning on the local API allows 3rd party software to interface with the thermostat such as a home automation system. Time API (setup step 29) Only appears when prior step for Local API is set to ON. This step allows the internal clock to be altered using the API.
Installar Setup Locking/Unlocking the Keypad To prevent unauthorized use of the thermostat, the front panel buttons may be disabled. To disable, or ‘lock’ the keypad, press and hold the MODE button.

About Advanced Features & Operation DEADBAND OPERATION - Controls one Heat and one Cool stage with a three speed fan (see below). The low speed fan for heat or cool is turned on when: The temperature spread from the setpoint is equal to or greater than: the setpoint plus the 1st stage dead-band (Setup Step 11, page 17). This 1st stage deadband is adjustable from 1-6 degrees and the default is two degrees.
About Advanced Features & Operation Calibration Under normal circumstances it will not be necessary to adjust the calibration of the temperature sensor.
