The parameters have the following meanings:
Temperature T1 and T2
In this menu the temperature measured at the sensor T1
and the sensor T2 is displayed.
dT (T1-T2)
In this menu the measured temperature difference
at the sensor T1 and the sensor T2 is displayed.
T1 Min/Max
In this menu the highest and lowest measured temperature
at the sensor T1 is displayed.
T2 Min/Max
In this menu the highest and lowest measured temperature
at the sensor T2 is displayed.
T1 Alarm Timer
In this menu the alarm delay time of the sensor T1 is displayed.
T2 Alarm Timer
In this menu the alarm delay time of the sensor T2 is displayed.
All other parameters have the same meaning as in the menus
mentioned before. Every menu point can be changed.
Example N2:
Set difference =5; Hysteresis = 2; T1 Ein (min) =30; T2 Ein (max) =70; Measured:
T2=20
Relay ON T1 = 30
Relay OFF T1 = 28
Programming and resulting action of REL2:
Relay 2 will switch ON if T2 ≥ T2 Ein (max)
Relay 2 will switch OFF if T2 ≤ (T2 Ein (max) – hystersesis)
Set difference =5; Hysteresis = 2; T1 Ein (min) =20; T2 Ein (max) =70
Relay 2 ON T2 = 70
Relay 2 OFF T2 = 68
