The family of controllers, consisting of several different versions, is suitable for simple to moderately complex HVAC and pumping applications. These can be supplemented with expansion options and a wide range of instrumentation accessories to create complete systems.

The family includes DIN rail-mounted versions with and without integrated displays and keypad, as well as a flush-mounted version for mounting in cabinets or panels. The portfolio also includes remote LED or LCD displays for 'blind' DIN rail-mounted versions of the controller.

The controllers are suitable for operation using a wide range of supply voltages. Versions are available for both 12 – 24V (dc or ac) and 100 – 240Vac.

A Modbus Serial Link or LAN expansion bus interface is integrated into the controller to allow the set up of a communication network. Peripherals such as a remote display, an I/O expansion module, or thermostats can be connected to the expansion bus.

Depending upon the type, all controllers are equipped with 14 to 22 integrated inputs and outputs, in various combinations of discrete and analogue based upon the version. Three different I/O expansion modules enable step-by-step expansion up to a maximum of 44 inputs/outputs.
