14.5 How To Adjust Water Flow Rate
Before adjust the water flow rate, make sure that the total water volume in the installation is 50 litres minimum for
heating side. The default setting is SPEED 6 for WH-MXC16G9E8. Please ensure the minimum flow rate is not less
than 13 l/min and not more than 50 l/min.
The available external static pressure (kPa) in function of the water flow rate (l/min) is shown in the P-Q graph.
Depend on the hydraulic system pressure loss and type, the water flow rate can be adjusted by remote control.
1 When the Air-to-Water Heatpump is in stop operation, press SERVICE button for 5 seconds.
2 Press / button to select menu S02 (PUMP SPEED ADJUST MODE) and press SET button to confirm the
menu.
3 Press SELECT button then press / button to change pump speed and press SET button to confirm the
pump speed.
4 Press OFF/ON button to exit PUMP SPEED ADJUST MODE.
During PUMP SPEED ADJUST MODE, we can select AIR PURGE function by pressing FORCE button.
In AIR PURGE function, the pump will operate ON and OFF for 10 minutes to purge the air in the hydraulic system.
Press again the FORCE button to exit AIR PURGE function. PUMP SPEED ADJUST
MODE will stop operation.
