Differential
Where setpoint is in response to some analog input such as temperature,
pressure, or humidity, include a setpoint differential to prevent short
cycling of control devices.
2.1.3.4
Motor and Flow Status Delay
Provide an adjustable delay between when a motor is commanded on or off and
when the control program looks to the motor or flow status input for
confirmation of successful command execution.
2.1.3.5
Run time Accumulation
Provide resettable run time accumulation for each controlled digital
output.
2.1.3.6
Timed Local Override
Provide user definable adjustable run time for each push of a momentary
contact timed local override. Pushes shall be cumulative with each push
designating the same length of time. Provide a user definable limit on the
number of contact closures summed, such as 6, before the contact closures
are ignored. Timed local overrides are disabled during occupancy periods.
