Wastewater System Controls

Standard and custom control panels are easily specified and ordered by completing the simple panel guide below. Panel pricing can be obtained by starting with a base panel list price found in the design section and adding the list prices of the desired options with panel point upgrades.

Control Series

S Simplex
SEQ Simplex Equalization
D Duplex
SEPR Simplex Equalization
T Triplex
SEPT Simplex Equalization w/ TOD Clock
Q Quadplex
DEPR Duplex Equalization
M Multiplex (five or more)
DEPT Duplex Equalization w/ TOD Clock
MET Multiplex Equalization
MT Multiplex Timer on Demand
CSEPR Combination Repeat Cycle Time
CSEPT Combination Equalization w/ TOD Clock

Alarm Option

(A) Indicator Light & Buzzer on Indoor Units, Red Light & Buzzer on Outdoor Units

Breaker Option

Place “B” for Breaker in designated space followed by the desired phase and voltage code.

1-Single phase
3-Three phase


On 3 phase systems, motor protectors are substituted for breakers and require a “P” instead of a “B.”

When fusible disconnects are required in place of pump breakers replace the “B” with an “F,” followed by the desired phase and voltage.

Enclosure Type

1-NEMA 1
2-NEMA 12

Many other enclosure types are available. Please see “Enclosure NEMA Type Chart” or “Enclosure NEMA Type Definitions” for details or contact our electrical engineering team for design support.
