Upm4 Circulation Pump - Immergas MAGIS HERCULES PRO MINI 6 Instructions And Recommendations

1.18 UPM4 CIRCULATION PUMP

The appliance is supplied with a variable speed pump that adjusts the speed to ensure the best possible performance.
Pump LED.
The LED flashes green when the pump is powered and the control signal is connected.
The LED lights up steady green when the pump is powered and the signal cable disconnected. In these conditions the pump
works at maximum speed and without control.
If the pump detects an alarm, the LED switches from green to red; this can mean one of the following failures:
- Low power supply voltage;
- Rotor seized;
- Electrical error.
For a detailed description of the meaning of the red LED, refer to the "Diagnostics in real time" table shown below.
The LED, in addition to being green or red, can also remain off.
It is normal for the LED to be off when the pump is not powered, whereas with the pump powered, the LED must be lit: if
switched off, it means there is a fault.

The symbol 2 stays on steady green (
tion is it necessary to distinguish between two cases:
- the appliance electronics are not requesting pump ignition => condition OK;
- the appliance electronics are requesting the pump to switch on => faulty condition (probable disconnection of the pwm signal).
If the pump detects an alarm, symbol 1 lights up red (
- Low power supply voltage.
- Rotor seized (Cautiously turn the screw in the centre of the head to manually release the motor shaft).
- Electrical error.

Pump release.
If after a long period of inactivity, the circulator is blocked, adjust the screw in the centre of the head in order to manually release the
motor shaft.
Take great care during this operation to avoid damage to the motor.
