2.0 Setup
1. Mount the controller box securely on a wall nearest to the Freeze/Thaw cabinet,
but away from water or extreme moisture.
2. Plug in all electrical devices on the cabinet such as heaters, cooling system
compressor, fan, and mechanical thermostat to the sockets at the bottom of the
controller box (Figure 2). All electrical connections have twist to lock plugs that
easily attach to the controller box. Each connection is different and no two
connections can be confused.

3. Open the door to the controller box and check the toggle switches inside the
controller box. If they are switched off as in Figure 3, switch heater, cooler, and
fan to the ON position.
