The CCC II is prone to brain-fade. The quickest way to see if that is the issue is to reset it.

To do a system reset:
• Make sure the CCC 2 thermostat is in the OFF mode.
• Simultaneously press the MODE and ZONE buttons. The LCD will display “IniT” and all available zones.
• Release the MODE and ZONE buttons.
• Press the ON/OFF button to exit system set up.

The process is described on Page 11 of the manual (attached).
