Welcome. My name is ***** ***** would be glad to assist.

Can you please, elaborate on the situation?

You have an exhaust fan and makeup air fan, correct?

Then sensors in the duct work?

What to you mean, "use instead of a control panel"?

Please give as much detail as possible.

Let me know and we can continue,

Thanks

The hood installer did not supply a hood controle panel with the contactorsand controlles.yes one 3phase exhaust one 3 phase make up air tht meet to go on at same time,yes two temperatures ensures in hood to turn on fans if temp goes up. Need an on off switch as we'll . There is no fire alarm involved and one ansul system with no electric under cooking hood. Can I use my own contactors or motor starters? Both fans on the roof with disconnects.

Ok,

Yes, you can use your own starters for the motors.

Use your own cabinets to house them etc.

Build it yourself is easier in most cases

They just need to wire into the ansul system for operation and shutdown in case of fire.

See the diagram below for the most common:The one showing lights and others will be your makeup fan etc, It must shutdown and the Exhaust must stay on when fa fire is sensed by the system.
