During the application of constant pressure water supply, when main pump frequency
operates at low speed (set via P061) due to reduction of water consumption and low-speed
operating time (P134) is achieved, corresponding multi-function contact shall be actuated
and auxiliary pumps stop.
P133 and P134 must be used in coordination with p060, P061 and multi-function output
terminal and mainly used for addition and reduction of auxiliary pumps. Refer to Figure 6-15
for details.

Shutdown pressure level mainly refers to pressure level occurring when main pump enters
the dormancy state; refer to Figure 6-16 for details.
Shutdown level continuous time refers to the duration time on the condition of shutdown
pressure level before going sleep; refer to Figure 6-16 for details.
Wake-up level refers to wake-up pressure level from dormancy state to recovery; refer to
