Graph 1 - UPM3L 25-75 130AZA Performance Curves
Pump speed can be selected by main remote controller setting (see Graph 1, red curves).
Adjust the pump speed setting so that the flow rate in the primary circuit is appropriate for the outdoor unit installed.
It may be necessary to add an additional pump to the system depending on the length and lift of the primary circuit. If
the additional pump(s) have current greater than 1A please use appropriate relay. If the second pump is being used in
the primary circuit between the cylinder unit and the outdoor unit then the signal cable should be wired to TBO.1 termi-
nals 1 and 2 (OUT1). In this position the pump speed MUST match the speed of the cylinder unit’s in-built pump.
Five pump speed control is available via FTC6 control.
