RDT300F001

The RDT300 is used mainly for controlling the flow temperature in heating/cooling systems. It contains six control models for weather-compensating control of the flow temperature in 2- and 4-pipe systems. The RDT300 can also be used to control intelligent unitary controllers. The RDT300 has two PI controllers, working independently of each other, and other time, alarm, command, sequence and limiting functions. The parameters are pre-set and enable the controller to be put into service rapidly. The RDT300 has a weekly and calendar time-siwtch with automatic change-over between summer- and winter-time. The following accessories are available: a plug-in memory for documentation purposes and for copying the setting parameters; a room operating unit with display.
