override air conditioner with timerReduce run-time of air conditioner.
Problem: air conditioner runs too much during peak electric prices. Programmable thermostat for the air conditioner can control peak usage by raising temperature and reducing hours of operation during peak times, but it cannot be programmed to limit actual number of run-time minutes per hour.

This diagram solves problem without compromising integrity of AC motor or equipment.

The din rail timer is programmed so timer is ON during peak hours. Any programmable timer will do the job but din rail timers are available in both 120 and 240 volt models. And 12-24 volt also.

When the din rail  timer is ON, it turns ON a relay, and turns ON a twin timer.
When the din rail timer is OFF, the relay is OFF and the twin timer is OFF.

One of the 24 volt wires from thermostat is connected to the com terminal on one side of relay. When the din rail timer is OFF, the relay is OFF, and the 24 volt thermostat circuit is routed straight to the contactor for normal operation of air conditioner.

When the din rail timer is ON, the relay is ON, and it switches the 24 volt thermostat wire away from contactor and to the Twin timer.
The twin timer is rated for either 120 or 240 volt. Twin timer is designed to turn on-off-on-off-on-off in endless repeat cycle. ON times and OFF times are set independently, and can be any value between .01 second and 99.99 hours.
For example, the twin timer ON time can be set for 40 minutes. And OFF time set for 20 minutes. This limits the operation of air conditioner to 40 minutes.
During the 40 minute period, the twin time routes 24 volts to the air conditioner contactor for normal operation.

After 40 minutes, the twin timer cycles OFF, and then air conditioner cannot turn on for 20 minutes until the twin timer cycles back ON again. When the 20 minutes expires, the twin timer again lets the 24 volts complete circuit to contactor for 40 minutes.
The cycle of 40 ON and 20 OFF continues as long as din rail timer is ON. Set the din rail timer to turn ON during peak electric prices.

Illustration on right shows same diagram except pulling power off the 240 volt AC circuit. Use 10-15 amp inline fuse to protect timer and relay circuit from 50-60 amp air conditioner circuit. Use terminals to connect the smaller wires to contactor. Prevent loose connection and risk of fire: Do not put two different gauge wires under the screw plate on contactor. Never put stranded wire under screw plate.

Information on contactors
contactor Basic contactor wiring:
Pull out the disconnect so electricity is OFF. Open wiring compartment on air conditioner. Use terminals to connect the smaller wires to line side of contactor. A capacitor will be connected to Load side of contactor.
Use 10-15 amp inline fuse on one of the two wires to protect timer and relay circuit from 50-60 amp air conditioner circuit. The fuse will protect entire length of circuit.
Prevent loose connection and risk of fire: Do not put two different gauge wires under the screw plate on contactor. Never put stranded wire under screw plate.

Estimated height of twin timer on the rail is 4-1/2" tall.
Off-delay timers will fit in 3-5/8" space if mounted directly to metal box, and not din rail/ twin timer on the rail is 4-1/2" tall. The box on left: twin timer is too tall and would be attached to side of enclosure.

Incoming power has two wires... connect these wires to terminals 5 and 6... and this will cause timer to operate and keep time.

Run a jumper wire between terminal 6 and COM terminal 2


Load (light bulb, contactor, etc) has two wires: connect one wire to terminal 5 and other wire to terminal 3

Terminal 1 is ON when timer is OFF.
It is the NC or normally-closed terminal.
Timer controls light bulb and 3-pole contactor
