how do I bypass a controll box ...installed by the power co.. that kills power to my ac unit?

Question

The box is a scientific Atlanta Model 225121

Answer 1

I agree with scuba diver above, be careful. Where I live only the utility company can remove the controller and they have a detector to determine whether you have disconnected or bypassed it. It is a crime to tamper with equipment they own and has a $1500 fine. Look carefully at the paperwork that came with it when they installed it (it is in the fine print) after they tell you how much energy you save with it.

Answer 2

It's easy.
The box is powered by the line voltage feeding the unit. 208-240 volts, depending where you live.
There are 4 wires on the box. 2 feeding the power to the box and 2 "switch legs". This is the switch. Kill power to both indoor and outdoor unit. The 2 wires that are the switch wires interrupt the control circuit via radio signal when the power company wants to shed loads. You will see the power wires being fed from where the power ties to the unit.
Just take the 2 wires that are the control wires-they will probably be wire nutted to another wire and usually blue and smaller than the power feeds. Take the wire nuts off, separate all 4 control wires. Connect the 2 wires together from the unit that were hooked to the box and just wrap up the 2 wires you just took off of the box. They have no power on them-they are just a switch. You're done.
Turn the power back on. Check to see if it works.
If you know how to do it, you can add a relay to the disconnected control wires so if the power company tests it, it will show a load.

Answer 3

Be careful and reconsider. Anytime you want to bypass a control box, you are playing with fire. Usually A/C units run on 220 volts. Thats enough to send you for a loop, or worse.

Not sure why you would want / need to bypass the unit but if I understand what you are trying to do here, this might be one for the service man.

hey you shouldn't do that
