Point Name/Description
First Reset
First Reset - Lower Temperature initially by: __ (deg) — The program requires a
priming reset when it is first turned on. The reset occurs after the program has first
been enabled in General Conditions & Status and Section 1 - Optimizer - Primary
Enable Conditions.
For the condenser water optimization, this determines the initial approach
temperature. The first reset, or priming reset, should be large enough for the
system to register the reset temperature and respond to it, but not so large that it
creates instability. If the temperature increment is too small, then the system won't
experience enough temperature change to determine if it saves energy.
The program measures the decrease (or possible increase) in kW/ton from this first
reset. It then determines what the next reset should be.
For the condenser water reset, the greater the value, the lower the temperature. We
recommend you set this value between 5 (deg) and 7(deg) for setup. The first reset
must be different from your resting approach temperature described in Section 3
Condenser Water Setpoint Reset (page 87).
Input Smoothing and System Response Time
Input Smoothing (0=min : 100=max): — This setting smooths the (kW/Ton) input
and removes erratic signals.
This smoothing is more complex and subtle than most. It does not overly smooth
the signal, but rather adjusts without shifting the output too much.
Input settings:
0 - no smoothing
1 - automatic minimal smoothing
Up to 100 (maximum smoothing or dampening)
