Coleman-Mach Bluetooth thermostat pairing and phone-limit prep

Use this when a Coleman-Mach Bluetooth thermostat needs pairing, six-digit ID, zone-name, or phone-limit notes before support.

Owner-safe checklist

• Record thermostat model, six-digit ID if shown, paired phone count, zone name, app screen, and whether the thermostat responds locally.
• Use only normal app pairing and button steps from Coleman-Mach guidance.
• Photograph the app screen, thermostat face, and visible model labels before support.
• Use Coleman-Mach support or qualified RV HVAC service if pairing fails repeatedly or controls behave abnormally.
