Wiring for T106 series

DTSP/ single pull double throw timer: single activation of timer switch can turn on either high or low speed on pump
Wire Intermatic T106 timer

T-106 timer 277 volts

T106 timer has NO NC terminals
When timer is OFF, then NC Load 2 is ON, and NO Load 1 is OFF
When timer is ON, the reverse happens, and Load 2 is OFF, and Load 1 is ON

Wire Intermatic T106 timer for 208 volts

T-106 timer 208-240 volts

T106 timer has NO NC terminals
When timer is OFF, then NC Load2 is ON, and NO Load1 is OFF
When timer is ON, the reverse happens, and Load2 is OFF, and Load1 is ON

Use this configuration for 2-speed 240Volt pool pump that runs continuously.
Use NO NC connections to change between High and Low speed

For 120Volt application,.buy T105 timer. 
Or replace WG1573 clock motor with WG1570


Resources
See wire sizes and load ratings
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.
Resources:
See wiring diagram for two timers

Wire colors will be different. For example white wire may be Low speed.
Check 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

T106 and T104 timer control 2-speed pump

T104 turns pump on-off
T106 changes pump from high speed to low speed
Wire this configuration when 2-speed pump is not ON all the time
Use T106 without T104 when 2-speed pump is ON all the time

T-106 timer: Single-pole Normally Closed

Normally Closed means the circuit is turned ON, and power is available to run Load.
When timer activates, the circuit is turned OFF

T-106 timer changes water heater temperature

Use timer for two different temperatures on electric water heater.

Either upper thermostat and element have power or lower thermostat and element have power. But not both at same time.

Install ECO-protected thermostat for lower thermostat.
Both upper and lower parts of tank are ECO-protected from overheating
Rewire tank so upper and lower parts are separate.
Use T106 timer to switch power between lower and upper parts of tank.

Normal operation, the lower thermostat and element receive power and keep tank at temperature set point. Upper thermostat and element have no power.
This is called 'redundant' water heater operation. This technique for heating tank more rapidly after cold water first enters tank. 
Resources:
How to wire thermostats

When timer activates, power to lower part of tank turns OFF. Power to upper part of tank begins. Upper thermostat is set for higher temperature.
Since tank is at regular temperature, the higher setting means upper element will turn ON and begin heating tank to higher set point.

Use this technique to heat water very hot for laundry cycle.
Disadvantage: The lower part of tank will cool rapidly as new cold water enters tank, so this technique is good for making short-term batches of hot water.

This technique applies to other timers:

Intermatic WHQ timer
Tork DTU40 timer
