WARNING
Improper installation, adjustment, alteration, service or
maintenance can cause property damage, personal
injury or loss of life.
Installation and service must be performed by a licensed

Application
The NTC unit controller is used on units not equipped
with a rooftop unit controller (i.e. [IMC M1−x, M2 or
M3 Prodigy
®
Unit Controller]) to allow access to the L
Connection
®
Network. The NTC may be used to control
rooftop packaged equipment or split systems and is
compatible with the Network Control Panel (NCP) versions
2.00 or later and Unit Controller (UC) software versions
2.08 or later. The NTC can control up to three stages of
cooling, two stages of heating, the blower, and outdoor air
dampers.
