Display shows "Con" and thermostat indicates connection mode

Possible Causes

Thermostat in Z-Wave/Zigbee inclusion mode, Gateway searching for devices, User long-pressed pairing button

Safety first: No wiring work is required.

Steps to troubleshoot:

1. Complete pairing:
- On your smart home gateway, start device inclusion.
- Follow the Heatit manual to confirm pairing while "Con" is displayed.
2. Exit connection mode:
- If you do not want to pair, press the back or mode button to exit.
- Alternatively, wait for the timeout period; the thermostat will return to normal mode.
