Venstar Skyport Communications, Installation Instructions Manual

When your salesman or service technician is in the home have him or her ask the homeowner if they would 

like to be able to change the temperature in the house from their smartphone. If they say yes, have the 

installer ask the homeowner if they can check out the Wi‐Fi in the house to see if it will support the 

ACC0454 Skyport Wi-Fi Key. Then take the smartphone to the vicinity of the thermostat and try to connect 

to the homeowner’s Wi‐Fi network. The installer may have to ask for the Wi‐Fi password. Next, by going to 

the settings icon on the iPhone, click on Wi‐Fi, choose the network, and enter the password. At this point 

the installer can see if the Wi‐Fi thermostat is going to hook up without any problems. If they can connect 

with the iPhone, iPad, etc., then the thermostat will also connect. Have the installer save the network name 

and password for the customer.

You can set up a Wi‐Fi thermostat at your office for a customer’s home or office. All you will need is an e‐mail 

address (you can get one free from Google) or you can use the customer’s e‐mail address and password if 

they choose to provide it. Set the thermostat up using your office Wi‐Fi and password for you router. When 

the installer goes out to install the thermostat all he or she will need to do is go to MENU on the home 

screen. Press the DOWN arrow and  then the  ACCESSORIES button.  Finally press the SETUP button.  The 

thermostat will then scan for all the networks in the house. Click on the correct network and enter the pass-

word to complete the process.

It is imperative that you have a supply air temperature sensor to troubleshoot and monitor their HVAC 

system. In most cases you can use the thermostat wire that goes from the thermostat to the rooftop unit, 

furnace, etc. Since the thermostat wire ends at the control panel of the unit, it is a short, easy run to put the 

temperature sensor in the supply air.  If you only have five wires then you can use one or two Add-A-Wires 

(ACC0410) to free up wires for the sensor. If you have a long run from thermostat wire you may not be able 

to use the thermostat wire. A separate wire must be run or use shielded wire. There is no way of telling if a 

problem exists until you try using the thermostat wire. If the temperature fluctuates two or three degrees 

when nothing is running, you will need to use shielded wire.
