INSTALLATION

1. Step 1 – Power Off Current System
   
   • All power must be disconnected before any installation or service is attempted. More than one power source may be supplied to a unit. Power to remote mounted control devices may not be supplied through the unit.
   • To confirm power is off, adjust the temperature on your current thermostat.
     WARNING: Failure to follow this step can result in personal injury and/ordeath from shock and electrocution.
2. Step 2 – Remove Faceplate
   Remove the faceplate of the current system. Most faceplates snap-off or feature small screws that will need to be removed.
   WARNING: If you see large thick electrical wires, wire nuts, or if your system is labeled 120V, 240V, or 277V DO NOT PROCEED. THIS THERMOSTAT IS NOT COMPATIBLE WITH THESE SYSTEMS
   
   WARNING: Failure to follow this step can result in personal injury and/or death from shock and electrocution.
3. Step 3 –
   If you are NOT replacing an existing IEC thermostat (model numbers E055-71520301 – E055-71520305, E055-71520316 – E055-71520319), proceed to Step 4.
   If you ARE replacing one of those thermostat models, you should not need to unwire or replace the existing backplate. Your new thermostat not only fits onto that backplate but has the same wire locations.
   If you see any wire attached to the RS terminal, you may need to change the remote sensor in the fancoil. See Owner’s Manual for details.
   If you see a wallplate in place behind the thermostat backplate, you will need to use a plastic shim (E055-71520329) to give a better mechanical fit. The shim is available for purchase through Parts. Contact your local sales representative for assistance. Proceed to Step 8.
4. Step 4 – Label & Disconnect Wires
   • One by one, apply a label designated to each wire you disconnect from your current thermostat.
     
     TIP: Before disconnecting any wires, take a photo of your current wire configuration with your mobile device.
     

     Wire from the old thermostat terminal marked	Function	Install on the new thermostat connector marked	Wire Color
     G1, GL	Low Fan Speed	G
     G2, GM	Middle Fan Speed	G2
     G3, GH	High Fan Speed	G3
     Y, Y1	chilled water valve (4 pipe) or hot/chilled water valve (2 pipe)	Y1
     W, W1	hot water valve (4 pipe) or strip heat (2 pipe)	W1
     H/C, WATER	2 pipe water temp sensor (open = hot, closed = chilled)	H20
     SWITCH	Dry contact for condensate overflow, occupancy sensor, door switch	CK1
     REMOTE	wired remote 10K thermistor	RS
     R, Rh, M, Vr, A	power (24v)	R
     C	common	C
     Y2	2-stage cooling	Y2

5. Step 5 – Remove Current Backplate
   Unscrew the current backplate and remove it from the wall. Be careful not to let the wires fall into the wall.
   
   TIP: If needed, wrap the wires around a pencil or pen to keep them from falling inside the wall.
   
6. Step 6 – Mount New Base
   • 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 separating the two pieces.
     TIP: If needed, wrap the wires around a pencil or pen to keep them from falling inside the wall.
     
   • Position the base against your wall, and determine if wall anchors from the current thermostat align with the screw locations of new base.
   •  If the base does not align with existing anchor holes, mark new screw locations with a pencil.
     Drywall: Drill a 3/16″ hole for the anchor
     Plaster: Drill a 7/32” hole for the anchor
   • Pull wires through the opening in the base and secure to the wall using provided screws.
     TIP: Use a level to ensure thermostat is properly aligned before marking screw locations.
     
7. Step 7 – Connect Wires
   • Match your previous wire configuration to the new base. One by one, connect each wire by inserting the metal end into the corresponding slot and tightening the screw.
     TIP: Use pliers to straighten wire before inserting into new base. Be sure to cut any excess wire so that the insulation extends to the terminal block. When the wire is installed properly to the terminal block, there should be no copper exposed.
8. Step 8 – Attach Thermostat
   Align the pins on the thermostat circuit board with the corresponding holes below the wiring connectors and push the top and the bottom of the plastic housing enclosing the display until it clicks into place, top and bottom.
   
   Front of thermostat should click into place easily. If you encounter resistance do not apply excess force – remove, check that the pins are straight and ensure there are no wires in the way and retry.
9. Step 9 – Switch Power/Circuit Breakers Back On
   Turn your fancoil back on.
10. Step 10 – Set Up Wi-Fi Connection
    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:
    • Successful connection to a local Wi-Fi Access Point with internet access.
    • Confirm receipt of a Skyport generated verification email (this only occurs once during the Skyport account setup).
    • A 6-digit code obtained from the thermostat is successfully entered into a Skyport account.
    • Successfully download and install the IEC Skyport app on your mobile device(s).
      Your thermostat operates on the 2.4 Ghz, Wi-Fi b/g/n band.
