De-blocking Grundfos pump, type UPM3:
Should the pump be blocked aer a period of disuse and fail to start, the status indicator LED 1 = red
and LED 5 = yellow will be displayed. The pump will make repeated autonomous attempts to start
electronically with maximum torque for a few seconds.
If the problem persists, the following manual
steps can also be taken:
In this case, please use the appropriate Phillips
screwdriver, e.B. Phillips No.2, and insert it into
the front opening in the middle of the pump
(see figures). Then press and rotate the piston
briefly in both directions with the aid of the
screwdriver.
The LogoTronic HIU controller must be permanently connected to the power supply when the
system is filled to counteract interference!

LogoMatic G2 stations (only S- and M-Lines) are fitted with a hot water throttle in the connecting
pieces of the plate heat exchanger. The model with gasket simplifies the exchange process.
