DO1 (0, 1K)
DO2 (1, 2K)
DO3 (OFF)
DO4 (OFF)
DO5 (OFF)
DO6 (OFF)
Setting of the desired function
Various functions can be allocated to the relay outputs "K1" and "K2". In case of the same function allocation for
"K1" and "K2", these work parallel.

Example to explain the display
0 = Relays D01 de-energized
1K = Programmed function (operating indication) for "DO1"
1 = Relay D02 energised
2K = Programmed function (fault indication) for "DO2"
OFF = No function assigned
OFF = No function assigned
OFF = No function assigned
OFF = No function assigned
Designation
No function
Relays remain always de-energized.
Operating indication (factory setting for "K1", non inverting).
Operation without fault, reports enable "OFF"
Fault indication (factory setting for "K2", non inverting).
Pulled up in operation without fault, with release "OFF" not dropped out.
Drops out in case of line and device fault and external fault at the digital input. Depend-
ing on programming in event of sensor failure.
When networked via the MODBUS Master interface, fault indication in case of faulty
MODBUS connection and fault on a member.
External fault separate with message at digital input (factory setting if terminals
bridged).
Limit modulation
Exceeding or falling below limits for modulation.
Limit "E1"
Whenover or falling below limits for input signal "E1".
Limit "E2"
Whenover or falling below limits for input signal "E2".
Only in controller modes (from
Limit: Setpoint offset (only for active Setpoint control circuit 1).
Deviation between actual value and setpoint to high.
Group control (Group 2)
Switching on fans depending on modulation
Group control (Group 3)
Switching on fans depending on modulation
Group control (Group 4)
Switching on fans depending on modulation
no function
For modes as temperature controller with additional functions
Heating function
Switch ON point: temperature = Setpoint +/- Offset
Switch OFF point: Temperature around hysteresis over switch ON point
Cooling function
Switch ON point: temperature = Setpoint +/- Offset
Switch OFF point: Temperature around hysteresis below switch ON point
