THE ELECTRONIC CIRCULATOR (low-consumption pump)
The product has a circulator with an electronic motor to save electricity and comply with the European regulations.
Electronic control of operation:
a) Control mode p – c
In this mode, the electronic controller keeps the differential pressure generated by the pump at a constant set value of H s.
b) Control mode p – v
In this mode, the electronic controller varies the pressure differential between the set value Hs and 1/2 H s. The pressu-
re differential varies with the volume fl ow.
c) Venting procedure
This procedure allows the expulsion of air present in the hydraulic circuit.
After manual selection of the "AIR" mode, the pump will automatically alternate between maximum and minimum
speed for 10 minutes. At the end of the procedure, the circulator will go to the pre-set speed. You can then select the
desired mode of operation
We summarize the signals that low-consumption circulators can display with the LEDs located on the pump controls
GREEN LED ON:
- Working pump, The pump works in base of its settings, Normally work
THE GREEN LED FLASH QUICKLY:
-
to set the power - Normally work
THE LED FLASH WITH LIGHT RED/GREEN:
-
pump will start to work automatically when the problem is solved - undervoltage U < 160V overvoltage U > 253V -
Engine temperature too high - Check the voltage 195V < U < 253V - Check the water temperature
THE LED FLASH WITH RED LIGHT:
-
doesn't start automatically -Change the pump
LED OFF:
- No supply voltage - The pump doesn't receive the voltage - The pump isn't connected on the motherboard
The led is defective - The pump is defective - Check the wire connection - Check if the pump works - Change the pump
