Configuration level
operation
This level is for configuring the regulator's basic functions.
To prevent interference by the end user, access
is made even more complex.
Switching to configuration level:
!
Press button
Arrow UP
and
Arrow DOWN
simultaneously for approx. 5 seconds.
!
The first parameter [C1] appears in the display.
!
Press button
Arrow UP
repeatedly until the last
parameter [C99] at working level is reached.
!
Press button
Arrow UP
again and hold down until [Pb]
appears in the display.
!
When [Pb] appears, hold down button
Arrow UP
and
simultaneously press button
Arrow DOWN
for approx.
3 seconds.
!
The display then shows the first parameter [P5] in the
configuration level.
Meaning of parameters
Param. P5: Function K1 in event of sensor failure
Param. P6: Function K2 in event of sensor failure
The switching status of the relay contacts
can be set for the event of a sensor failure.
0 = OFF in the event of failure
1 = ON in the event of failure
Parameter P10: Hyst. mode for target temperature T1
Parameter P11: Hyst. mode for target temperature T2
(with reference to the compressor relay)
0 = symmetrical
1 = one-sided
The hysteresis determines the
value by which the temperature
of the medium may deviate from
the corresponding target tempe-
rature before the relay contact is
activated. See diagram.
If the contact in question is for
cooling, the hysteresis is always upwards. In the case of
heating contacts it is below the target temperature (cooling
or heating contact is set at configuration level).
In the "symmetrical" hysteresis mode, the value selected is
distributed on both sides of the target temperature.
Param. P20: Limit for target temperature T1 downwards
Param. P21: Limit for target temperature T1 upwards
Param. P22: Limit for target temperature T2 downwards
Param. P23: Limit for target temperature T2 upwards
Setting of input limits for target temperatures at working and
programming levels.
