Application Notes
 If FLOW is oscillating while FLOW STPT is constant, then the flow loop requires
tuning.
 The controller, as shipped from the factory, keeps all associated equipment OFF.
 Spare DOs can be used as auxiliary points that are controlled by the field panel
after being defined in the field panel’s database. The combination of DO 3 and DO
4 may be used as auxiliary motor points. If using this pair of spare DOs to control a
motor, you must unbundle MTR2 COMD and set MTR SETUP.
 Spare DOs can be used as auxiliary points that are controlled by the field panel
after being defined in the field panel's database. DO 3 (HEAT STAGE 1), DO 4
(HEAT STAGE 2), and DO 5 (HEAT STAGE 3) control the stages of electric heat. If
less than three stages are being controlled by the application, the DOs that are not
used will be spare. If DO 6 is not used for an Autozero Module, it will be a spare.
