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.
