Low ambient control for central air

[Shane]

Hi guys. I have to install a low ambient control on a 1.5 ton central air conditioner. Does anyone have any suggestions on a specific make or model? Right now it cuts out at about 50-55f and the client needs it to run in cooler conditions. 

Cheers

The easiest way is to install a Mars #33341 pressure switch to cycle the cond fan. There are electronic controls available that do a better job but are also more expensive.
