SEQUENCE OF OPERATION
General
The Carrier Integrated Staging Control Board (ISC) is intended for
use with a standard thermostat capable of three cooling stages. Af
-
ter initial power to the board, a Green LED will blink with a
1 second duty cycle indicating the unit is running properly. When
the unit is not running properly, the Green LED will blink along
with Red LED lights. The Red LED light configuration will indi
-
cate the type of error the board has identified.
The ISC board can be remotely shutdown by removing Jumper 4
and wiring to the Remote Shutdown terminal. The Smoke Control
Module can shut down the unit by removing Jumper 3 and wiring
to the Smoke Shutdown terminal. A smoke alarm can be obtained
by wiring to the Smoke Alarm terminal.
The crankcase heater will run at all times except when the com
-
pressors are running. An auxiliary power supply (24Vac) available
at TB-4 Terminal is provided to power auxiliary equipment. An
optional Phase Monitor Relay can be wired to the PMR terminal
by removing Jumper 5.
