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.
Function
Designation
OFF
No function
Relays remain always de-energized.
Operating indication
(1K)
Operating indication (factory setting for
“
K1
”
, non inverting).
Operation without fault, reports enable
“
OFF
”
Fault indication
(2K)
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 error
(3K)
External fault separate with message at digital input (factory setting if terminals
bridged).
Limit modulation
(4K)
Limit modulation
Exceeding or falling below limits for modulation.
Limit E1
(5K)
Limit
“
E1
”
Whenover or falling below limits for input signal
“
E1
”
.
Limit E2
(6K)
Limit
“
E2
”
Whenover or falling below limits for input signal
“
E2
”
.
Setpoint Offset
(7K)
Only in controller modes (from
2.01
)
Limit: Setpoint offset (only for active Setpoint control circuit 1).
Deviation between actual value and setpoint to high.
Group2
(8K)
Group control (Group 2)
Switching on fans depending on modulation
Group3
(12K)
Group control (Group 3)
Switching on fans depending on modulation
Group4
(13K)
Group control (Group 4)
Switching on fans depending on modulation
(14K)

2.Heating
(9K)
Heating function
Switch ON point: temperature = Se/- Offset
Switch OFF point: Temperature around hysteresis over switch ON point
2.Cooling
(10K)
Cooling function
Switch ON point: temperature = Se/- Offset
Switch OFF point: Temperature around hysteresis below switch ON point
