Digital Temperature Interlock

Control Circuit Diagram (Standard Control)

This Control Panel only provides control power to 
signal operation of supply and exhaust starters.
Starters are 

NOT 

provided by manufacturer. 

Starters to be provided by, wired and mounted by others.

Wiring for additional sensors (optional)

This is an example of a generic wiring diagram for standard control. This diagram has 12 sensors  

which provide temperature interlock function for two exhaust fans and one supply fan.  

(All starters provided by others, external to this control box).
