How to wire Dayton Off Delay Timer
Use only 600 volt wire.
Lamp cord, extension cords are not rated 600 volt.
Use copper wire only. Aluminum wire is fire risk and should be avoided or installed by professional.

Generally ... use same size as other wire in circuit

armored cable
Non metallic flexible cables must carry ground wire, but do not have hazard of short circuit causing injury from shock.

Armored steel cable can be used as a grounded connection, and will protect wires from damage. Metal can be energized from an insulation failure.

All conduit ...metal, plastic ... flexible and rigid ... must be attached to structure, and attached to enclosures, boxes.
Movement, damage and deterioration are major cause of electrical failure.

Electrical tools must be insulated.
Always best to disconnect power, but insulation failure, lack of proper grounding, grounded neutral, lack of GFCI, out-of-code wiring, generator operating without transfer switch, and other problems still pose a risk to anyone working on electric power ... even when breaker is off.

stranded wire
600 volt 12 ga Stranded wire ot THHN wire is good for conduit with multiple wires ... but stranded cannot be installed under screw terminals on outlets, switches, timers etc without risk ... of heat causing splayed strands ....that come loose ... and begin to arc. Connect stranded to short piece of solid copper wire, and attach solid to screw terminal. Do not solder residential or commercial wiring.

Project wire, extension cords, thermostat, bell and automotive wire are not rated for residential or commercial wiring. Only wire maked 600 volt can be used for permanent household wiring.

Protect wiring from damage
Use nipper instead of pliers or screwdriver for removing staples (and nails). Do not damage cable or wires inside cable.

-Code says: Cable SHALL BE secured without damage to the outer covering. NEC sec. 336-15

dayton off-delay timer Sequence of operation:
Push  momentary-on switch
Countdown begins after momentary-on is released
Dayton timer begins countdown. Load turns ON.
When Dayton timer reaches end of countdown, circuit going to Load is turned OFF

Momentary on switch can be any circuit.
When circuit turns off, then the countdown begins, and runs until countdown is finished.

The Load
Motor, lights, fan cannot exceed 1 amp.
Volts x amps = watts. Amps = Watts ÷ Volts. 120 volt 100 watt light bulb = .83 amp
Recommend using contactor

Fuse
Recommend 1 amp fuse on hot wire going to timer

Use contactor because coil is less than 1 amp:
Match coil voltage and voltage used to operate timer

3-way switch is convenient
Any switch position will start the delay
Click switch up starts delay... click switch down starts delay
Load turns off after delay period expires

Why the 3-way switch diagram works... because the switch is ON full time.
When the timer receives power... the load turns ON until delay period expires... but timer is still receiving power. If you temporarily stop power from going to timer, by clicking the 3-way switch to another position, then the timer resets, the light turns ON again until the delay period expires.
Load remains OFF until power is stopped and started again.

If you use single-pole switch... then the switch must be turned off and then back on to restart delay.
If single-pole switch is turned off, then load remains off

recirculation off delay timerLarger image
Load
Max rated load on the timer is 10 amp.
Using a relay will preserve life of timer since motor start-up pulls surge of amps through terminals 8-7 on the one-shot timer.
How it works:
Set twin timer to one shot mode ... instructions shown in section above.

Connect 120 or 240 volt AC power to terminals 10-9.

Connect other wires as shown.
Off delay uses terminals 8-7 as shown (or 11-12) ... while on delay would use 7-6.

Push doorbell button, or momentary toggle switch ... this will start the inkbird one-shot timer timer (do not energize the doorbell wires on start switch circuit with any voltage).

Timer turns ON and begins countdown. Timer terminals 7 and 8 turn ON. This causes the pump to turn on ... or causes the relay or contactor coil to energize. Circuit to recirculation pump turns ON.

When countdown expires, terminals 7 and 8 turn OFF, pump turns off, or relay coil or contactor coil is de-energized and pump turns OFF.
Twin timer that is set to one-shot mode, and powered by 120-240V, will operate .9 seconds to 99 hours. So the pump can run any length of time: for example 1 hour or 21 minites etc.
Do not connect power to terminals 1 thru 5.

LADT2 on delay timer          
Larger image

On delay contactor block

On delay timers are designed to delay start time.
Once the LADT2 timer block activates, the countdown begins.
When countdown ends, the timer's internal relay activates.
When LADT2 relay activates, the NO normally-open contact closes, and NC normally-closed contact opens.
For example, when circuit is 'closed' then power travels across terminals and light bulb turns ON.
When circuit is open, the light bulb is OFF.
NO and NC contacts give two different wiring choices.
LADT contacts are 'dry,' and have no power until Hot wire is added to either the NO or NC terminal.
Contact block attaches to contactor.
When contactor activates, that action activates the LADT2 countdown. LADT series are pneumatic timer attachments.
LADT timer is activated by mechanical action of contactor, instead of electric current.
Adding timer block, allows the contactor to control additional circuit with time delay. So a second process can begin or stop shortly after contactor activates.
