Robertshaw Refrigeration Controller TC-900E-2HP

The Robertshaw TC-900E-2HP is an electronic refrigeration controller rated for a 2 horsepower load.

A refrigeration controller of this type typically manages the complete operating sequence of a small refrigeration system rather than performing temperature cycling alone: compressor control with anti-short-cycle protection, defrost scheduling and termination, evaporator fan control including the delay after defrost, and alarm functions.

Consolidating these into one device replaces what would otherwise be a temperature control, a defrost timer, a fan delay, and their associated wiring. The benefits are fewer components, less wiring, and a single point at which the system's behaviour is configured and can be reviewed.

The corresponding consideration is that a single controller failure disables the entire system rather than one function, and that configuring the controller correctly requires understanding all the parameters it governs rather than setting a single temperature.

Controllers of this type store their configuration in parameter lists, and recording the settings of an existing controller before replacing it saves considerable time, since a replacement arrives at factory defaults which will rarely suit the installation.

Applications include commercial refrigeration, walk-in coolers and freezers, display cases, and food service refrigeration.
