T775A/B/M Series 2000 Electronic Stand-Alone Controllers

INSTALLATION INSTRUCTIONS

 

 

 

 

PRODUCT DESCRIPTION

 

 

 

 

 

The T775 electronic stand-alone controllers are the next

 

 

 

 

generation of commercial and agricultural controls

 

 

 

 

capable of remote sensing of temperature and providing

 

 

 

 

switched and/or proportional outputs to various types of

 

 

 

 

loads.

 

 

 

 

 

 

 

 

 

Five models have analog (modulating) outputs for

 

 

 

 

actuator and motor control, and NEMA-4 weatherproof

 

 

 

 

enclosures are available for wet environments.

 

 

 

 

IMPORTANT

 

 

 

 

 

 

 

 

 

 

Each T775A/B/M controller is an operating

 

 

 

 

 

control, not a limit or safety control. If used in

 

 

 

 

 

applications requiring safety or limit controls, a

 

 

 

 

 

separate safety or limit control device is

 

 

 

 

 

required.
