Start-Start= This value determines the minimum time between chiller starts. The chiller must run the time selected
before it will start again. If the chiller runs less than the time selected the timer will have to time out before another start
is allowed. This is to eliminate chiller cycling that could damage the motor by starting to frequently.
Evap Recirc= This value determines the time the chilled water pump must run before the start sequence is started. This
value insures that the chilled water system has an adequate load to start the chiller. It also insures that the chilled water
pump has time to establish constant flow in the system to prevent nuisance water flow switch trips.
Stop-Start= This value is similar to the Start-Start already described. This time ensures that there is adequate time
between stop to start for the chiller to become stable or pressures to equalize. This can also be used to minimize short
cycling.
