Managing home comfort is simple when you have just one HVAC system. But many modern homes rely on multiple systems – a heat pump paired with a furnace, a boiler connected alongside a central AC, or a network of mini-split units spread across different rooms.
This complex setup introduces a major challenge: How do you keep all systems working efficiently without constant manual switching?
That’s where Cielo Linked steps in as a breakthrough solution. Designed as part of the Cielo smart home HVAC ecosystem, Cielo Linked allows you to intelligently connect and control multiple HVAC systems so they function harmoniously, automatically, and efficiently.
If you want to minimize energy bills, increase comfort, and reduce the hassle of managing different heating and cooling units, this guide will walk you through everything you need to know.
What is Cielo Linked?
Cielo Linked is a cloud-based platform within the Cielo ecosystem that allows you to link multiple HVAC systems (central heat pumps, furnace boilers, ductless mini-splits, and conventional heating & cooling systems) so they operate intelligently as a unified climate control solution.
Instead of manually switching systems on and off, Cielo Linked automates everything. The platform uses real-time conditions and your preferences to determine which system to run, when to switch, and how to optimize overall efficiency.
Why Homes Need an Intelligent Linking System
Homes today often have a mix of HVAC systems. Without automation, this results in:
- Wasted energy
- Higher monthly bills
- Systems working against each other
- Manual adjustment of multiple HVAC systems
Cielo Linked addresses all of these challenges by ensuring every system works as one unified solution.
How Does Cielo Linked Work?

Cielo Linked brings multiple HVAC systems under a unified smart automation platform. Whether you have a central HVAC system, mini-split, a heat pump, or a boiler/furnace, Cielo Linked ensures they operate in harmony to deliver consistent comfort and maximum efficiency.
The links can be created by setting activation conditions (triggers) on one device (let’s call it the triggering device), and defining link actions for integrated control. Once the condition is met, the link will be activated, and actions will be performed on the linked devices (action device).
Moreover, what makes it special is that Cielo Linked provides unified control for various HVAC systems, regardless of type or brand. This means you can manage a Mitsubishi mini-split alongside a Haier one, or link a Toshiba system with a Daiken central air conditioner using the Cielo Home app.
All you need to do is connect your central air conditioner with the Cielo Smart Thermostat and your room air conditioners with Cielo Breez mini-split thermostats, and you’re good to go!
Your best choice to make any mini-split, window,
or portable AC smart. Enhance your comfort and savings.

Understanding Triggering and Action Devices
For better understanding, your devices can be broadly classified into two categories: triggering devices and action devices. A triggering device initiates a request to respond to specific events or conditions on another device.
While an action device is responsible for executing a particular action in response to a trigger.
For example, you can set a trigger to turn on Breez Max (action device) on cool mode at 73° F when Cielo Smart Thermostat (triggering device) reaches 75° F. This can do wonders to counter cooling or heating discrepancies in a 2-story house and more. 
Compatible Cielo Devices
To use Cielo Linked, each HVAC system in your home needs to be paired with a compatible Cielo device. These are:
Smart Thermostats for Central HVAC System
Smart Thermostats for Mini-Splits
How Does Cielo Linked Enhance Your Smart Home Experience?
Cielo Linked offers a host of benefits that transform your smart home experience into something truly remarkable. You can create links by setting activation conditions, selecting a triggering device, and defining actions for integrated control. Let’s discover how:
-
Auto Adaptation to Outdoor Weather Conditions
Balancing comfort and energy efficiency in homes that rely on both a central system (furnace/boiler and central air conditioner) and ductless mini-splits can be challenging. Homeowners often end up manually switching between the multiple systems, which not only complicates temperature management but can also increase utility bills.
Cielo Linked eliminates this guesswork with smart, automated decision-making. It continuously monitors indoor and outdoor temperatures to determine the most efficient heating or cooling source at any given moment. You simply set a weather-based trigger on your Cielo smart thermostat and define the corresponding action for the Cielo mini-split thermostat.
In winter, when outdoor temperature goes above 5°F or any other temperature that you have set, Cielo Linked prioritizes mini-splits, which warm specific rooms efficiently and reduce furnace usage. Once temperatures fall below 5°F, it switches to the furnace or boiler to provide stronger whole-home heating during extreme cold.
In summer, mini-splits take the lead during mild weather, delivering targeted cooling without running the central AC unnecessarily. But when outdoor temperatures rise sharply and cooling demand increases, Cielo Linked can shift to the central air conditioner or use both systems together to maintain optimal comfort.
For example, during a heat wave when the outdoor temperature crosses 100°F, your bedroom air conditioners in the upper story can also turn on to supplement the central air conditioning. This will ensure an optimal indoor climate when outdoor conditions remain harsh, and one unit struggles to maintain a comfortable environment in various parts of the house.

Convenience: Simplifying Indoor Climate Control
If you live in an area with an extreme cold climate, then you must know the struggle to keep your home cozy when temperatures drop below freezing. And on top of that, keeping pipes from freezing and protecting household items are additional challenges. Instead of going to each unit to change its settings, or realizing late you forgot to turn on the attic heat pump, there’s a simple solution! You can create a link using Cielo Linked, and all of this would be executed automatically without any manual intervention required.
For example, you can set a link to switch your Cielo Smart Thermostat to heat mode when the outdoor temperature drops to freezing (say 50°F) while simultaneously turning off room air conditioners. Additionally, mini-splits in the attic and garage can be set to minimal heating (say 43°F on heat mode) to prevent freezing temperatures and pipe bursts.

Coordinated Automation For Multiple Mini-Splits
With Cielo Linked, you can prioritize comfort while avoiding unnecessary energy usage. With the power to control multiple devices simultaneously, you can ensure that energy consumption is optimized and aligned with your desired comfort level.
For example, you can sync your office air conditioner with your home air conditioner. You can set a link to turn on the home air conditioner when you turn off the office AC, saving energy.
Benefits of Cielo Linked
Intelligent & Automatic Switching
The biggest advantage of Cielo Linked is its ability to automatically switch between systems. No more guessing when your heat pump becomes less efficient or when your mini-split should take over for improved comfort. You set your rules once, and Cielo Linked handles the rest.
Example:
- Use a heat pump when the outside temperature is above 5°F
- Switch to the furnace when the temperature drops below 5°F
This type of automation ensures that only the ideal system runs at the right time.
Maximize Energy Efficiency & Lower Bills
When systems aren’t linked, both may run unnecessarily, or the least efficient one may run longer than needed. Cielo Linked eliminates these inefficiencies by:
- Prioritizing the most energy-efficient option
- Preventing simultaneous system use unless required
This results in significant energy savings, especially in homes with heat pumps, mini-splits, or older furnaces.
Reliance On Eco-Friendly Systems
Heat pumps and mini-splits are far more eco-friendly than traditional gas furnaces or boilers. Cielo Linked lets you prioritize green options whenever possible. As a result, you lower your carbon footprint by reducing reliance on fossil fuel-based systems and enjoy smart energy management across your home.
