Parameters

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 the level is within 5% of Span (P007) of the OFF setpoint, the next pump is not started

P122 Pump Service Ratio [MR 200]

Selects pump usage based on the RUN time ratio rather than last used.

P111 Relay Control Function

 

 

 

This parameter only relates to relays with P111 = 54 or 55.

To make this parameter useful, assign it to all of the pump relays. The number assigned to each pump relay represents the ratio applied to decide the next pump to start or stop.

Notes:

The MultiRanger will not sacrifice other pumping strategies to ensure that the ratio is held true

If the pump relays are set to the same value then the ratio equals 1:1 and all pumps are used equally (preset)

Independent Relay Failsafe (P129)

P129 Relay Failsafe

Sets how individual relays react to a failsafe condition, to allow for more flexible programming.
