Temperature Switch TS 2125
pumpenlaufzeit (pump running time)
Here you can input the length of time which the pump is activated. Input values:
1 min. – 30 min..
All other input parameters are identical to the descriptions mentioned above.
examples for the action of the relay 1:
Relay1 will be switched ON if:
T1 ≥ (T2 + Difference) AND after the measuring interval has passed.
When the relay is switched, the pump running timer is activated, defining the
maximum running time of the pump.
Relay one will be switched OFF if:
T1 ≤ (T2 + Difference – Hysteresis)
OR after the pump running timer has passed.
If the relay has been switched off, the pump running time is reset to 0.
example:
The water temperature is detected in a cycle of 30 minutes. If the
temperature difference of 5°C is detected between T1 and T2, circulation pump
will be switched on. The hysteresis is preset at 2°C. The pump is programmed
to switch off after 5 min running time.
For this example the following inputs need to be made:
Difference: 5°C
Hysteresis: 2°C
Measuring interval: 30 min
Pump running time: 5 min
