Wiring temperature control panel.
For a system controlling more than one hood connect hood sensor 2 to s3 s4 hood sensor 3 to s5 s6 and hood sensor 4 to s7 s8.
The panel and all penetrations must maintain the proper nema rating.
2 control circuits are unique in that many controls now use industrial networking cabling technology.
Conductors of different circuits.
More accurately the pictured setup uses a 240vac 30a gfci breaker installed at the service panel to make the 4 wire dryer outlet that the control panel dryer cord plugs into gfci safe.
They are a necessity for external control devices as they allow the digital.

This gfci breaker is an expensive item but vital to making the whole brewery safe.
Terminal blocks secure wires to the controller.
The very popular tri rated cable rated under bs 6231 is a kind of high temperature fire retardant cable specifically designed for control.
Some multi loop temperature control systems can have up to 32 loops of control in a din rail mounted package not much longer than 8.
In addition to the obvious need to be able to turn the temperature control panel off an on the manual off switch is an important safety feature.
They also reduce wiring by having a common connection point for power supply and communications interfaces.
