If you cannot reach the long side, then position it as close to the end of the mat as possible. The floor sensor wire should not run under or over any of the mats.
Yes, you need to connect the mats to a thermostat. For best efficiency, the thermostat should have an in-floor temperature sensor. Mats should not be direct-wired to the power source.

The QuietWarmth system requires a dedicated 20 amp circuit for each thermostat or power module. In a 120V system each circuit can power up to 150 square feet of mats. In a 240V system each circuit can power up to 300 square feet of mats.
For the QuietWarmth radiant heating system we do not offer a thermostat without the GFCI protection, as it is a requirement in the National Electrical Code for radiant floor heating systems. If there is GFCI in the thermostat and the breaker, it could cause nuisance tripping. You should reach out to your local code enforcement for guidance. They may be able to waive the requirement since that will be a dedicated circuit that is already protected by a GFCI.
You can operate multiple QuietWarmth heating mats with one thermostat. For a 120V system you can power up to 150 sf; for 240V system you can power up to 300 sf per thermostat. If your area exceeds that, you can use a Power Module to extend that coverage. A Power Module will require its own dedicated 20 amp circuit.

You should reach out to your electrician for guidance on replacing the breaker if possible, or another option for thermostat.
