Time Program Preparation When preparing the Time Program, set the switching points for system start/stop to
the latest possible time because EOV automatically advances these times, if
necessary.
Also, you must set the Optimization variable to Yes in the Time Program for system
start/stop.
Time Program Switch Point With EOV, the Time Program does not use step changes in the room temperature
setpoint for optimized system start/stop as is the case with EOH. Instead, the Time
Program includes XD1 status changes in the calculation of optimized start/stop time
points. Therefore, XD1 must be a Time Program user address. This requirement is
the only way advance monitoring of the switch point is possible.
Time Program Optimization EOV releases the optimization attribute in the Time Program (in the Datapoint for
Excel Web / Excel Web II) that has the user address assigned to XD1. This release
enables optional system switching. Otherwise, EOV uses the switching points in the
Time Program.
No Setpoint or
Integrated Controller EOV does not provide the setpoint and does not have an integrated controller. The
controller application program must provide regulation during the system shutdown
phase.
OR (Excel Web / Excel Web II)
Function OR output becomes TRUE(1) if at least one input is TRUE(1). NOR output is the
inverted OR output.
I/O Dialog Box
Inputs Two through thirty two digital inputs.
Output Two digital outputs.
Internal Parameters None.
PID Controller / PID
Function Proportional-Integral-Derivative controller that regulates an analog output based on
two analog values (one is a controlled variable; the other, a reference variable) and
operating parameters. The controlled variable is the variable that should be held
constant, for example, a room temperature. The reference variable is the prescribed
changeable value of the controlled variable, for example, room temperature setpoint.
I/O Dialog Box
The PID controller can also operate as a P, PI, or PD controller if you zero the
Integral and/or Derivative values in the internal parameters dialog box.
