## Flair Bridge Pro: The Perfect Interlock Solution

Flair’s Bridge Pro ensures compliance with Canadian construction codes by enabling true staged heating control. This solution prevent mode conflicts—ensuring a mini split isn’t cooling while baseboard or backup heating is active.

## The Quebec Interlock Requirement

Per the [Construction Code, Chapter I.1 (Section 5.2.8.5 #3)](https://nrc-publications.canada.ca/eng/view/ft/?id=130d14ba-579e-4820-9234-bfba19127207) and [RBQ Construction Code](https://www.rbq.gouv.qc.ca/en/laws-regulations-and-codes/construction-code-and-safety-code/construction-code/), Quebec mandates interlock mechanisms in multi-source HVAC systems to ensure efficiency and safety.

- ## Interlock Function:

An interlock ensures a mini split cannot cool while an electric baseboard or other heating system is engaged.

- ## Flair’s Staged Heating Solution = Interlock Compliance

Flair inherently provides this interlock function, coordinating multi-system heating intelligently—no extra wiring or controllers required.
