9 - NOMINAL SYSTEM WATER FLOW CONTROL
9.3 -
Water flow control procedure (variable
speed)
TD units include a water pump that automatically adjusts the flow
to maintain a constant temperature difference.
No control is required at start-up, but the control mode must be
selected in the unit control by a CIAT service representant
9.4 - Available system pressure
The available pressure curves for the TD units are given for the
higher variable speed of the pump (maximum available pressure).

Data applicable for:
-
Fresh water 20°C
-
In case of use of the glycol, the maximum water flow is
reduced.
