LC multi-function display with plain text display:
Different menu languages can be selected
Simple start-up by operating modes:
Typical operating modes, e.g. for air conditioning, refrigerant or ventilation technology can be selected.
Typical settings can be made easily: e.g. minimum speed setting, limitation of the maximum speed, inversions and limits. Setting, e.g. for 2-step mode
2 analog inputs for sensors or setting signals:
analog input E1 and E2: Setting by operating modes or manually programmable, e.g. 0-10 V, 0-20 mA, 4-20 mA
analog input E2: programmable, e.g. comparison with sensor 1, difference to sensor 1, average value formation, setpoint setting, setpoint adaptation (e.g. outdoor temperature-dependent)
2 digital inputs D1 und D2:
Programmable, e.g. enable, switchover setpoint 1 or 2, switchover control or manual mode, switchover E1 or E2, invert control function, output limitation, display of external fault, reset
1 analog output A1:
Setting by operating modes or manually programmable, e.g. output signal proportional to modulation, output signal proportional to input signal, invertible, 10 V constant voltage, group control
2 digital outputs (relays) K1 and K2:
Setting by operating modes or manually programmable, e.g. operating indication, fault indication, limits, external fault at digital input, activation of external devices, e.g. heating, shutters, group control, fans, etc.
Integrated motor protection function:
Connection possibility for PTC thermistors or alternatively thermostats (TB or TP).
Interface RS485 MODBUS RTU:
Integration into bus system
For e.g. software update, communication with PC
Activation set protection against unauthorised access, restoration of made settings
Querying of occurred events, operating times, etc.
