How to Use the ClimateMaster iGate 2 Thermostat

Is there a ClimateMaster 360Link thermostat?

Not that I can find. I went back through ClimateMaster’s thermostat literature and none of it uses the name 360Link. An earlier version of this page did, and that was my mistake. ClimateMaster’s own literature lists the iGate 2 (AWC99U01) as the replacement for the iGate ATC32U03, and that is the thermostat this page covers. If your thermostat is the older ATC32U03 with buttons, use my ClimateMaster thermostat walkthrough instead.

How do I use the iGate 2 screens?

Swipe left or right, or tap the dots, to move between screens. Here is what each one does on the ClimateMaster iGate 2:

One thing surprises people. When you switch from HEAT to COOL, the unit may not change right away. ClimateMaster builds in minimum on and off timers to protect the compressor, so give it a few minutes before you decide something is wrong.

How do I connect the iGate 2 to Wi-Fi and the myUplink app?

The iGate 2 works with ClimateMaster’s myUplink app, or the website at myuplink.com. Here is the order ClimateMaster lays out:

1. Make an account in the myUplink app or at myuplink.com.
2. Join the thermostat to your home Wi-Fi. It only works on 2.4 GHz, so pick that network if your router has two.
3. Keep your phone within about 15 feet of the thermostat while you set it up.
4. Tap the Wi-Fi status icon on the thermostat to see the serial number and the token the app asks for.

The Wi-Fi icon tells you where you stand. Green bars show signal strength, red means no connection, and blue means it is installing an update.

Where do schedules and alerts live on the iGate 2?

You can see the schedule on the thermostat, but ClimateMaster has you make permanent schedule and vacation changes in myUplink. Register the thermostat there and a fault does three things: it shows as a banner on the screen, it emails you, and it pushes a notification to your phone. It can also warn you when the house gets hotter or colder than a limit you set. Out here that matters on a farmhouse, a lake place or a rent house nobody is living in that week, where a dead heat pump in January can freeze pipes before anybody notices.

What should I do when the iGate 2 shows an alert?

Read the banner and write it down. The iGate 2 keeps a LOG of the five most recent events, faults included, for whoever services it. Leave RESET LOG alone. That list is the first thing I read when I get to your house. ClimateMaster does not publish a homeowner reset for a unit lockout, and its control manuals say not to restart a unit until somebody finds and fixes the cause. My ClimateMaster fault code guide explains what each code on the unit’s board means.

The iGate 2 log can show a loop alert like LOW LOOP PRESSURE. On the Oklahoma systems I service, that sounds worse than it usually is. In the 700+ geothermal jobs Hartzell’s Heat & Air has on record since 2017, I have never replaced a loop field. Pressurizing and flushing a loop that picked up air came up 150+ times. Loop pumps and flow centers came up 45+ times.

How do I reset the filter reminder, clean the screen or lock the iGate 2?

After you change the filter, go to the FILTER screen and press RESET to restart the timer. The CLEAN screen freezes the touchscreen for 10 seconds so you can wipe it without changing anything. The lock is off out of the box, and its default PIN is 0000, so if you turn it on for kids or renters, set your own. After five wrong tries, the thermostat locks for 15 minutes and sends the owner a notification.

What is E-HEAT on the iGate 2, and when should I use it?

E-HEAT runs only the backup electric heat, with the compressor off. ClimateMaster sets auxiliary heat to Supplemental by default, which means the strips help the heat pump on the coldest mornings without you doing anything. E-HEAT is for when the geothermal side is down. ClimateMaster’s manual for its ATP32 thermostats says emergency heat is “significantly more expensive to operate than the heat pump compressor, and should not be selected unless the heat pump compressor is not operational.” If you are living on E-HEAT, call me.

What does a ClimateMaster geothermal service call cost?

At Hartzell’s Heat & Air, the geothermal diagnostic is $348 flat. Weekday, night or weekend, it is the same $348, and it is the same for my maintenance plan members. I check loop pressure, refrigerant charge, the desuperheater, controls and the heat exchanger, and you get a written report and a quote before I leave.
