BOILER PUMP NOT FROM ACV
page 3 / 3
Use the following settings to determine the values of the previous section's parameters by
respecting the data presented in the summary table of the flow rates below:
Model (kW) 40 60 70 80 100 120 150
Min. flow (l/min) 9.5 19.2 19.2 38.3 38.3 50.0 57.3
2322 (%) with our circulator kits 34 42 35 40 40 45 42
Max. flow (l/min)
28.7 39.3 50.0 69.3 71.7 86.0 103.8
2323 (%) with our circulator kits
74 78 78 75 77 74 79
Follow steps 1 and 2 to find the minimum flow command and repeat these same steps to set the
maximum flow command.
Step 1
Line No. Value
• Menu Input/output tests
Define the control value in % to control the boiler pump speed. The 0-100% scale roughly
corresponds to the 0-10V control scale.
Request via manual control
Test output P1 (7713) ---% (0 to 100%)
For example, if the pump from the kit is used for a 70kw boiler, the value to be entered here
would be 35%.
Step 2
Line No. Value
• Generator diagnostics menu
Check that the water flow in the boiler is as expected
Reading the boiler water flow
Boiler flow (8366) --- (l/min)
For example, for a 70 kW boiler, the value to be shown here is 19.2 l/min (+/-0.2 l/min).
If the flow rate for your model does not match what is shown in the above table, please reset a
speed control beginning from step 1.
