Looks like Summer Stage is included!

For background: there is a new issue with the ACIQ TL04-1 thermostat where constant fan is impossible to disable when the unit is in cool mode. I think this was due to a firmware update in response to complaints that constant fan wasn't available in cooling mode, but now they've made it so the fan will run continuously in cooling mode regardless of the settings.

I had a conversation with ACiQ, and was informed that continuous fan in cooling mode is a feature, not a bug, and that all their units are designed to operate this way. They also said they don't support their thermostats when used with non-ACiQ equipment, so anybody using one of these with a Mr. Cool is out of luck.

For reference, I have a Mr. Cool Versa Pro connected to the TL04-1, Firmware V.100094. Let's hope they fix this and allow us to disable constant fan mode like before.

Service Menu Code: 134679

Edit to add: Here is a screenshot of my service menu under the 94 firmware. The “Temp Comp” settings have been removed. https://imgur.com/a/wnRTQyw
