How to diagnose and control the operation of the accumulation pump using the device interface?

The parameter d.12 is used to check the power and operating status of the accumulation pump (0 = stopped to 1-100% = running). In the accessory settings (d.27 and d.28), option 3 corresponds to the tank loading pump command. During maintenance, control program P.6 moves the 3-way valve to the central position for filling, while P.0 executes an automatic purge of the heating and hot water circuits.
