Description

One Smart Thermostat for ACiQ Communicating & Traditional HVAC Systems

The ACiQ TL04-1 Smart Thermostat gives you the flexibility to control your HVAC system in two different ways. Use it as an advanced communicating thermostat with compatible ACiQ equipment or set it up as a traditional 24V thermostat for most conventional heating and cooling systems. Built-in Wi-Fi, an easy-to-use touchscreen, and smart-device control through the ACiQ Home app make it simple to manage your comfort at home or away.

Key Benefits

Communicating & 24V Control - Use with compatible ACiQ communicating equipment or as a traditional 24V thermostat.
Ideal for ACiQ Inverter Systems - HA/HB communication lets compatible ACiQ equipment communicate directly with the thermostat.
ACiQ Home App Control - Adjust temperatures and manage your comfort from a compatible smartphone or tablet.
Broad HVAC Compatibility - Works with most traditional 24V heating, cooling, and heat pump systems.
Easy Touchscreen Control - A modern touchscreen makes everyday temperature and system adjustments simple.

Smarter Comfort. Sleek Control.

The ACiQ TL04-1 Smart Thermostat is engineered to bring precise, intelligent control to your home’s HVAC system. Compatible with both standard 24V wiring and HA & HB communication protocols, it delivers flexibility for new builds or system upgrades.

One Thermostat, Two Ways to Control Your HVAC System

What makes the TL04-1 different is its ability to work as either a communicating or traditional thermostat. Pair it with compatible ACiQ equipment using HA/HB communication for direct communication between the thermostat and HVAC system, or configure it for traditional 24V control with most conventional HVAC equipment. This flexibility makes the TL04-1 a smart choice whether you're building a new ACiQ system or upgrading the thermostat in an existing home.

Get More from Compatible ACiQ Inverter Equipment

When connected to compatible ACiQ equipment through HA/HB wiring, the TL04-1 becomes a communicating thermostat that allows the thermostat and HVAC equipment to share information directly. This makes it an ideal control option for compatible ACiQ inverter systems and helps the equipment take advantage of its advanced operating capabilities.

Control Your Comfort with the ACiQ Home App

Connect the TL04-1 to the ACiQ Home app for convenient control from a compatible smartphone or tablet. Adjust temperatures and manage comfort settings remotely, giving you easy access to your HVAC system whether you're at home or away. The TL04-1 is also compatible with the NetHome Plus app for smart-device control.

Also Works with Traditional 24V HVAC Systems

You don't need a communicating ACiQ system to use the TL04-1. It can also be configured as a traditional thermostat for most 24V HVAC systems, including compatible one- and two-stage heating and cooling equipment and heat pumps with auxiliary and emergency heat.

FAQ's

Customer Questions

Is this thermostat required to be connected to the internet to work for keeping temperature. If network is down for a few days it will still work?

The ACiQ TL04-1 Smart Thermostat is NOT required to be connected to the internet to perform its basic function of keeping the temperature. If you have any further questions, please call us and we will be happy to assist you.

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.

Does this require shielded wire to be ran? Does it need to be stranded?

No. The TL04-1 does not require shielded or stranded wire. The installation manual specifies that the wiring should meet CL2 requirements and that the thermostat terminals accept 16–24 AWG conductors, but it does not require shielded or stranded cable. Standard HVAC thermostat wire is appropriate for most installations, provided it meets local electrical codes and the system manufacturer's requirements. If you have any further questions, please call us and we will be happy to assist you.

Can the thermostat actually stop the blower in cooling mode between cooling cycles using HA/HB wiring?

Yes, but with HA/HB wiring the TL04-1 does not directly control the blower through a separate G wire; the indoor unit’s communicating logic determines whether the blower stops between cooling cycles, and on some current firmware the fan may continue running even when cooling is satisfied. If you have any further questions, please call us and we will be happy to assist you.

I am wanting to know if the ACIQ TL041 will allow me to set a temperature I want the unit to come on when paired with the matching gas furnace? This is a propane unit and I am wanting to save on the propane usage and allow the ACIQ 3 ton Extreme condenser heat pump to handle most if not all the heat we will need in the middle Tennessee area. It varies in temps here from the low teens to upper 50's in the winter. I hope this makes sense! Any help on this would be most appreciated.

Yes, the ACiQ TL04-1 supports dual-fuel operation and allows you to set an outdoor-temperature changeover point so the 3-ton Extreme heat pump handles most of the heating, with the propane furnace taking over when temperatures fall below your selected setting. If you have any further questions, please call us and we will be happy to assist you.

Can it work in communicating mode on air handlers with X1 X2 X3 X4 instead of HA/HB?

No, the ACiQ TL04-1 thermostat cannot work in communicating mode on an air handler using an X1, X2, X3, X4 terminal layout because its communication protocol is specifically designed for HA/HB lines (typically matching proprietary Midea-family or specific inverter systems), whereas X1–X4 lines belong to an entirely different manufacturer communication protocol (such as Trane/American Standard communicating systems) that uses a proprietary digital data language the TL04-1 cannot translate. If you have any further questions, please call us and we will be happy to assist you.
