Attention
Resolution of the PT1000 sensor: 1 Fahrenheit or
0.6 Centigrade.
Do not use the datapoint associated to PT1000 in
control logic which requires a resolution less than
1 Fahrenheit.
The analog input with PT1000 can be used in
control loops only when connected to
CPO-VAV2A via a transducer with 0-10V rating.
Additionally, you must use the ComfortPoint Open
Studio tool to define custom characteristics which
matches the selected transducer.
The PT1000 sensors connected directly with
CPO-VAV2A can be used only for monitoring and
reporting purposes.
The connection between CPO-VAV2A and wall modules are
illustrated in Figure 15 through Figure 21.

Attention
The CPO-VAV2A controller does not control the
LCD display of the T7560 Wall module. It handles
the temperature sensor input, Bypass/Fan, or Fan
Control Input. The LCD Display must not be used
to get the Effective Occupancy state of the
controller.
