Procedures
Construct a frame from 2x4’s to support a control panel and attach as shown above.
Attach the boxes for the switches, controller and outlet to the panel.
Attach the solid state relay on top of the heat sink and attach to the backside of the panel frame.
My system utilizes a home 15-amp breaker circuit.  But the representatives at Omega Electronics recommend the use of a Fast Blow Fuse and Box to protect the controller system.  I’ve used my brewery several times without problems.  If you are concerned about the reliability of your home breakers/fuses, install the fast blow fuse and box.
Wire the switches, controller, outlet, SS relay, thermocouple, element, pump(s) and plug-in cord in accordance with the electrical plan.  See section 11, Electrical Plan.
Attach cover plates.
 
How the Recirculating Infusion Mash System works
When switched on, the controller display will flash system configuration information for a few seconds and will then show the current temperature.  It will be in output mode and will power the heating element when the temperature falls below the setpoint.  The controller determines current temperature through the thermocouple and then switches on the solid state relay, which sends power to the element keeping the mash within 1⁄2 degree of the setpoint.  Pump 1 must be on whenever the heating element is on.  As a safety feature to avoid burning the mash, the system is wired so that the heater will be powered only when both the controller output 1 indicator and pump 1 is on.
 
A complete description of the proper use of the RIMS is in the last section, “Brewing, Step by step guide”.
