Does this work with the ACiQ ACIQ-60-HPD / ACIQ-48-ACL-B to easily set up the backup propane heat? On the last installation we used the Honeywell T6 and it took a bit to get the settings adjusted correctly. In Connecticut we had to show that the back up propane was locked out to 20 degrees F.
Yes, the ACiQ TL04-1 Smart Thermostat is compatible with the ACiQ-60-HPD / ACIQ-48-ACL-B system and should allow you to set a backup heat lockout temperature like your required 20 degrees F for propane (auxiliary) heat. If you have any further questions, please call us and we will be happy to assist you.

Giveb that ACiQ heat pumps are built by Midea, am I right to suspect that this thermostat is a re-branded Midea MTL04-1? That would make it likely compatible in HA/HB communication with recent Midea central heat pumps. I have a Midea system that was installed with a third party 24v thermostat and looking to upgrade
Yes, you are likely correct: the ACiQ TL04-1 thermostat is widely considered a re-branded version of the Midea MTL04-1 wired controller and is designed for direct HA/HB (RS-485) communication with ACiQ/Midea central heat pump systems, allowing you to fully utilize the system's variable-speed features. If you have any further questions, please call us and we will be happy to assist you.
