General information concerning the control unit
The ST 200 & 521 controller series are intended for general use in refrigeration systems.
2.1 Product description
The ST-BOX 200 is used for thermostatic temperature control of refrigeration systems. The
controller can be supplied with 90...250 V AC and has four output relays that can be freely
programmed to control a compressor, an evaporator fan, lighting or other necessary outputs.
An output for DC fans is also available. It is operated either directly on the box or via a
separate, connectable display.
The ST-BOX has a three-digit display, 3 operating keys and 7 LEDs that are also used to
indicate the status of the relay outputs. The parameters are set at various operating levels,
where access is increasingly difficult for reasons of security.
The controller is networked via an ST bus interface.
