Like asking what is the spark gap for my V8 engine. There are numerous V8 engines out there and each is a bit different. As with the Penn 266 series condenser fan controls, there are numerous models, which is yours and how it corresponds to the existing equipment is in the air at this moment.
Here is a publicly accessible brochure and install manual on that series of controller, outlining what the numerous models are and what they can and can't do with the transducers installed.
The question is , can we resume the default setting, when another programation have been done. no matter which 266, thanks .
