P7.0 Actual temperature
Display of actual temperature measured at sensor S1 in PI control or at sensor S2 in
P+PI control.
P7.1 Alarm code: 0-4
Note: Press (+) key for 5 seconds to change from P7.0 to P7.1.
Here the alarm code can be read off. Alarm codes mean the following:
0 No alarm
1 Sensor S1 not connected.
Sensor S1 short-circuited (alarm from fire thermostat)
Danger of frost at sensor S1 (systems 1, 2, 3, 4 only).
2 Danger of frost at sensor S2 (system 1 only)
3 Danger of frost at sensor S3 (not system 6)
Alarm from frost thermostat KP (not system 6)
4 Danger of frost at sensor S4 (not system 6)
In the case of several alarms simultaneously, the lowest number is displayed. An
alarm can only be reset when its cause has been eliminated.
P7.2 Systems 2 - 6: Compensation II:
±
(0-90)°C
Setting of temperature that gives base point for compensation II.
Compensation influences sensor S1 reference (see P6.2).
The value indicates the temperature at which compensation begins. The sign of the
value indicates maximum or minimum compensation.
(+): max. compensation
(-): min. compensation
P7.3 Compensation factor II:
±
(0-1-20)
Setting of the value indicating compensation influence on reference temperature
(see P6.2).
The sign of the value indicates increase or reduction of reference temperature on
compensation.
(+): reference increased
(-): reference reduced
P7.4 Proportional factor - Kp: 0 - 30
Setting of proportional factor - Kp, that indicates the change in reference
temperature in the PI circuit for each degree of error in the P circuit.
P8.0 Normal temperature: -20 to 110°C
Setting of required normal temperature. The setting applies to sensor S1 in PI
control or sensor S2 in P + PI control.
P9.0 Reduced temperature: -20 to 110°C
Setting of required reduced temperature. The setting applies to sensor S1 in PI
control or sensor S2 in P + PI control.
