The second parameter set can be used to store and – if necessary – to restore follow-
ing actual parameters: control parameters, setpoints and setpoint configuration,
process offset, ramps, softstart and alarm configuration.
The factory setting of the second parameter set is identical to the actual parameter
set.

mode
In case of a sensor break, the regulator mode is au-
tomatically changed to “ manual mode” using the
last valid output ratio.
Manual mode is indicated with a leading "H" in
the setpoint display, followed by the output ratio.
The output ratio can be changed manually.
In following cases the output ratio is 0 %:
• if the output ratio was 100 % at the time of the
sensor break
• if a setpoint ramp is active
• if the control deviation from the measuring
range was > 0.25% at the time of the sensor
break
• if parameter P (xp) = 0 (OFF)
• if softstart was active at the time of the sensor
break
A few seconds after the sensor break has been rec-
tified, the controller returns to automatic operation
and calculates the required output ratio.
Alarm contact 1 can be programmed to activate an
additional signal in case of sensor break.

mode
Device operates as a power controller. Temperature
regulation function is not active.
"PROCESS display" shows the actual process value.
“ SETPOINT display” shows a leading "H" followed
by the actual adjustable output ratio.
Negative value: cooling, positive value: heating
The output ratio can be changed manually.
