TABLE 12 LEAD LAG PID VALUES
Very Slow
Gradual
(Recommended)
Medium Fast
P 60 20 15 10
I 120 120 60 30
When tuning the PID take note that larger values for the Proportional and
Integral will yield a more gradual response from the boiler(s) when there are
loop temperature uctuations whereas smaller values will make the boiler(s)
more responsive. Derivative is not used. The Integral parameter when disabled
(set to zero) may cause the boiler(s) to approach but never reach setpoint. Faster
responses generally result in oscillating supply temperatures and a greater rate
of boiler cycling. See Table 12 for factory recommended values, eld adjustment
outside of these values may be required for optimal response performance.
From the Lead Lag Master Conguration screen Select the box labeled Advanced
Settings in the bottom right hand corner. Use the left and right arrows to scroll to
the screen labeled Algorithms. The two rows labeled lead selection method and
Lag selection method need to be set to measured run time. Refer to Figure 56 for
factory default settings:
