Disable Cooling Regulation Prohibition in the Installer Menu

Follow these steps to remove the cooling restriction for the specific room:

1. Access the Installer Menu on your Thermacome 523432 thermostat by holding the designated menu button (typically the second button from the left) for 5 seconds while in the OFF state.
2. Navigate through the configuration parameters until you reach the setting labeled 'Interdiction de régulation froid sur zones'.
3. Change the parameter value from 'Enabled' (or '1') to 'Disabled' (or '0') to permit cooling for that zone.
4. Save the changes and exit the menu to return to normal operation.
5. Verify the fix by selecting 'Cool' mode on the thermostat interface; the system should now allow activation without blocking the signal.
6. Check the central 8-channel regulator to ensure that the seasonal lockout or high-level system settings have not also restricted cooling for that specific channel.
