The following table lists the parameters which are available for
monitoring by Metasys supervisory systems. For details of configuration
procedures and override possibilities, refer to the technical documentation
of the system which is to be used.
Table 4: Supervisory System Parameters
*Note: For 0-10 VDC control signal outputs, OCM1 and OCM2 operate
in parallel and indicate the output level in Heating or Cooling.
Therefore, at the supervisory system, OCM1 should be monitored
as the "Heating/Cooling Control Output" and L1A can be
monitored to indicate whether the controller is in heating or
cooling mode. (Requires Metasys Release 9.0 or later.)
