DPT-Ctrl-MOD with a two-setpoint feature
A two-setpoint feature has been added to DPT-Ctrl-MOD to control differential pressure or volume flow. The device has a binary input to select between two setpoints. The source of the binary input can be, for example, the time extension button of the CDT2000 transmitter. In this case, the DPT-Ctrl-MOD selects the higher setpoint for volume flow to boost ventilation. Modbus communication makes it possible to adjust the parameters straight from the automation system.
