NCM-3z Non-Expandable Zone Control Panel

The NCM-3z works with single stage and heat pump systems. Multiple configurations of Single Stage systems, 2 heat / 1 cool systems and 2 heat / 1 cool Heat pump systems are all compatible with heat/cool single stage thermostats and 2 heat / 1 cool Heat pump, as well as any Smart Wifi thermostats.

The four-button menu control is provided for easy set up while scrolling through the LCD Display screen. The LCD display will provide real-time "system status" feedback, such as Supply Air Temperature, System Mode of Operation, Fresh Air Cycles remaining and Status of the on-board safety interlock features.

Fresh Air option allows the NCM-3z to operate as a 2-zone system with the (3rd) third zone acting as a Fresh Air intake. The NCM-3z will calculate the amount of fresh air allowed based on "Minutes of Fresh Air per Hour" along with the Square Footage of the home, the number of occupants in the home and the size of the intake duct installed.

The NCM-3z Safety Circuit allows the installer to connect safety devices directly to the zone panel. This feature was designed with the new A2L refrigerants in mind, though this feature also works with wet switches, condensate pumps, smoke detectors, and fire alarms. If the safety device contacts open, the NCM-3z will shut down the heating or cooling demand and either turn the Indoor Fan "On" and open all dampers or turn the Indoor Fan "Off" and close all dampers.
