T106 2-speed pump
>2-speed pool pump wire colors may be different than illustration
>For example High speed might be White and Low speed Yellow
Connect Low speed to NC terminals. High to NO terminal.

T-106 timer: 2-speed 240Volt pump

>Timer acts as a high-low switch for continuous-running 2-speed pumps.
T106 timer does not turn pump off. Use P1353 for 2-speed pumps that turn off
>Or use 2 timers, and wire first timer before T106.

See wiring diagram for two timers

Wire colors will be different. For example white wire may be Low speed.
wiring diagram and instructions for pump
Typically Low speed is running most of the time
So connect Low speed wire to NC terminal 1, and High speed wire to NO terminal 4.
Set timer to turn ON during times when High speed is needed.
Minimum on-off is 1 hour.
>Pump operates continuously. Install another timer on L2 Hot line to turn pump ON-OFF
Pump motor must be grounded

T10604R wiring for 2 speed pump

For controlling 2-speed pool pump with minimum cost and long-term reliability. Replacement parts are available and installed DIY with screwdriver.
240 volts supply voltage is connected to Terminals 1 and 2 on T104 timer on right side.
Both timers have a clock motor that rotates the yellow dial once per day. The dial can hold up to 12 sets of trippers. Typically, the swimming pool timer has 2 sets of trippers for 2 OFF and 2 ON each day. Both clock motors are connected to terminals 1 and 2 on the T104 timer.

The way it works: T104 timer controls the on-off function for the pump. When T104 turns on, power is sent to T106 timer. T106 timer has NO and NC terminals. One set of terminals or the other set of terminals is ON at all times. When power arrives from T104, the power is sent to either low or high speed on the pool pump. Trippers on the dial of the T106 timer control when the pump is high speed or low speed. When power arrives at the filter pump from T106, the circuit is completed through terminal 4 on T104.
how to bond control panel
Example shows solar panels... but also includes pool control centers etc
Pump must be bonded to ground wire and then directly to ground rod... in addition to regular ground wire coming from electric service

Ground all electrical devices, and all household grounds together and bond to main breaker panel and to ground rod. Do not ground to water pipe:  Make sure ground is connected to ground rod.
Water heaters and metal water pipes will corrode with stray current.

Modern pex water lines are not affected, and cannot be used as a ground.

When installing new water heater, water pipe, doing repairs on plumbing, installing new electric service etc... check that all electric is connected to dedicated ground wire that is bonded to ground wire that is connected to outdoor ground rod.

Bonded means steel electric panel enclosure must be directly connected to ground wire that is connected to local ground rod.
Applies to outdoor control panel and pool pump at point of installation/ local codes vary / consult local electrician/ some codes may allow bonding to metal conduit that enters the soil at point of installation... but stray current corrosion can cause deterioration of this conduit/ codes vary for grounding for many reasons, such as different soils offer different resistivity to grounding/ for example dense wet soils conduct to ground better than loose dry rocky soils

Safety when testing wires:
Never touch wet or previously flooded appliance.
Never stand on wet surface when working on electric.
Never stand on bare soil, put down dry boards.
Tape tester leads to wood sticks to keep hands away from power.
Use non-contact voltage tester before touching wires.
Never touch or lean into any made of metal.
Remove metal objects from pockets.
Do not use oxygen or fuel accelerants in same room as electrical repairs

When removing insulation from wire, do NOT score or put cuts on surface of copper wire. Doing so increases resistances on wire and creates weak point.
