Parameters
P119 Relay Logic Test
Forces the relay control logic into an ACTIVATED or DE-ACTIVATED state.
This parameter tests site wiring and control logic programming. Forcing the relay to an
activated or de-activated state is similar to the HydroRanger 200 detecting an event and
responding to it. Helpful in testing new installations and diagnosing control problems.
Pump Setpoint Modifiers (P121 and P122)
These parameters provide alternate ways of starting the pumps in the pump group. See
the Pump Control section on page 51 for descriptions of the pump control algorithms.
P121 Pump by Rate
Sets the pump relays to accept control by rate of level change once the first ON setpoint
is reached.
Use this function when multiple pumps are to be controlled by rate of level change rather
than by setpoints.
The delay between pump starts is set by P132 Pump Start Delay.
This only applies to any relays set to pump control (P111 = 50 to 56).

Notes:
All pump control relay ON and OFF setpoints must be the same value
If level is within 5% of Span (P007) of the OFF setpoint, the next pump is not started
