PTA2 Connection on Digital Output 2 for Analog Cooling

When proportional modulating cooling is required, the M2000 Rooftop controller must be equipped with
a PTA2 v.1. interface to create an analog 0-10Vdc output signal. The PTA2 input is connected to Digital
Output 2 on the M2000 Rooftop controller. The input pulse range must be set to 0.1-10 sec. For more
information on the PTA2, consult the Specification Sheet and the Installation Guide for the PTA2.
