11 - NOMINAL WATER FLOW CONTROL WITH VARIABLE-SPEED PUMP
11.1 -
Pump flow/pressure curve
Units with variable-speed hydraulic module include a water pump that automatically adjusts the flow to maintain a constant pressure
or constant temperature difference.
No control is required at start-up, but the control mode must be selected on the unit interface (refer to the DYNACIAT LG/LGN
Connect’Touch control manual).
11.2 - Available external static pressure (Low-pressure pumps, units with hydraulic module)
Data applicable for:
-
Fresh water 20°C
-
In case of use of the glycol, the maximum water flow is reduced
