P143 (G) PEAK LEAD TIME
Enter the estimated pump running time (in minutes) required to pump the
level from the highest Relay A Setpoint (P112) to the lowest Relay B
Setpoint (P113) levels.
This value defines the time before the high energy cost period, when the
HYDRO+ should start pumping to ensure the level is as far as possible
from the Relay A Setpoint (P112) level.
(If the level is already within 5% of Span from the Relay B Setpoint (P113)
level, no action is taken).
If multiple pump stations are series linked, ensure the Peak Lead Times
entered are sufficient to attain the desired level in all stations before the
high energy cost period occurs.
values: 0.000 to 1440
INDEPENDENT PEAK RELAY SETPOINTS A / B
P144 PEAK A SETPOINT
Enter the value (similar to Relay A Setpoint, P112) to be used for the high
energy cost period.
This feature allows the level to go beyond the normal Relay A Setpoint
before a pump is started.
values: 0.000 to 9999 (preset = 0.000)
