DMUX-4J Connection on Output 2 for Stage 3 or 4 Cooling

When 3 or 4 stages of cooling are required, the C1000 Rooftop controller must be equipped with a
DMUX-4J. The DMUX-4J input is only connected to Output 2 on the C1000 Rooftop controller. The
DMUX-4J must be configured to "Sequenced Relay Control" with a 1 second pulse resolution. The "Triac
Input Selection" jumper must be set to normal signal input and the "Power Type Selection" jumper must
be set to AC power. The DMUX-4J outputs are then connected to the rooftop unit (see Figure 12). Each
of the DMUX-4J outputs have connections for "Normally Closed" and "Normally Open" operation, so use
the connection that is compatible with your rooftop unit. For more information on the DMUX-4J, consult
the Specification Sheet and the Installation Guide for the DMUX-4J.
