4.6 U1000 iQpump Presets and Functions
• When the "Disable Pre-Charge" digital input (H1-oo = 8C) is closed, even momentarily
• When the PID feedback satisfies Pre-Charge level (P4-01):
Feedback is greater than Pre-Charge Level (P4-01) (forward-acting PID, b5-09 = 0)
Feedback is less than Pre-Charge Level (P4-01) (reverse-acting PID, b5-09 = 1)
• When the "Low Water" digital input (H1-oo = 8C) deactivates. A digital input must be programmed to "Low Water"
(H1-0o = 8F). The input is configured in P1-30 (0: normally open, 1: normally closed).
