The CAREL ON/OFF temperature controller is an IR33 series invention with 1 relay output for use in static refrigeration units. It is specifically used for the refrigeration installer as they enable selection from a range of pre-loaded applications, eliminating the need to program the controller parameters. This controller then just needs to be wired up and installed in the panel. The controller has up to 3 NTC inputs. It is housed in a compact panel mounting enclosure and is powered from 115VAC to 230VAC. It can be connected to a network for monitoring and programming using the optional RS-485 serial interface.
