You can use one of the following to link to the tower or pump condenser water setpoint
control.
BACnet ANO2, which writes to a remote Setpoint Analog Value
BACnet Analog value, which is read by a remote Setpoint ANI
NOTE If using a BAV, link the Optimized (Final) CWS Reset Setpoint BAV to the
remote cooling tower logic reset BACnet Analog Input. This output is a temperature
setpoint signal and when fed through the condenser water logic, should override
the current CWS temperature setpoint.
The BACnet Analog Input should go through its own safeties and ramps before
setting the CWS temperature setpoint.
The Heartbeat may be used to communicate a healthy signal to the receiving
program. Use if required or desired, but not necessary.
