Consult this manual for all the information you need to install the HVAC thermostat safely.
*It is strongly recommended that a qualified professional perform the installation.
The HVAC Smart thermostat is compatible with several systems, whether for new installation or replacement:
The HVAC smart thermostat is compatible with various platforms and voice assistants:
The concept of heating or cooling stages is fundamental to understanding how modern central heating and cooling systems work, particularly those that use a heat pump.
A stage corresponds to a separate source of heat or cooling in your system. A thermostat that manages multiple stages is called a multistage thermostat.
There are two main types of central systems for homes:
1. Single-stage system
This is the simplest system. It has a single operating speed and a single source of heating or cooling.
2. Two-stage or multi-stage system
These systems are designed to be more efficient and comfortable. They have two or more levels of power for heating or cooling.
a) First stage (low intensity)
The first stage is the main source and operates at low capacity (often 60% or 70%).
b) Second stage (High intensity or Auxiliary)
The second stage only kicks in when the first stage is unable to maintain the temperature, often because it is extremely cold outside.
| Function | Stage | Heating/Cooling source | When is it used? |
| Heating | 1st stage | The heat pump itself. | Moderate temperature (for example, above 0°C). |
| Heating | 2nd stage (Auxiliary) | Electric heating elements or the auxiliary furnace. | When the outside temperature is very low (for example, below −14°F), making the heat pump ineffective. |
| Cooling | 1st stage | The heat pump (cooling mode). | In hot weather or at the beginning of the cycle. |
| Cooling | 2nd stage | Full compressor capacity. | In very hot weather or for rapid cooling. |
To ensure that the thermostat is compatible with your current installation, you must first validate your system’s current connections and verify that they are compatible with the thermostat.
You can refer to the various connection diagrams illustrated in the installation manual to validate compatibility.
