Network Input Configuration
Figure 38 shows the network input configuration screen. Table 24 describes the
parameters.
Heartbeat Alarms
An alarm occurs if the period between received values of these variables exceeds
the value you enter into the Heartbeat column. For more information, see the
section.
Cooling Override Value
Enter the minimum value for the cooling internal control loop. In
dehumidification process, this is the smallest value for the
cooling outputs. For example, if you have one modulating
cooling valve and the value for the cooling override is 55%, the
valve always opens at 55% or more in dehumidification mode.
Fan Speed Override Value
Enter the value for the fan speed in dehumidification mode. If
you have 3 fan speeds, and you want speed 2 to be open,
enter the value 66.66%, which corresponds to 2 fan speeds on
a 3 fan speed possibility (2/3).

Description
Heartbeat
Sets the maximum time between updates for the associated network input.
When the heartbeat interval has passed without an update, the network input
enters the heartbeat failure state, and its value becomes invalid.
Persistent
Allows the network variable to remain in memory after a power failure and/or
reset. Do not make frequently changing network variables persistent.
