If the water inlet temperature to the condensers is lower than the permitted values, it is recommended to use a three-way modulating valve to guar-
antee the minimum water temperature required.

• Hot water temperature produced 30÷54°C for versions B / 30÷55°C for versions T-S-Q;
• The minimum inlet water temperature allowed is equivalent to 20°C.
DS:
• Hot water temperature produced 50÷70°C with 5÷10 K allowed water temperature differential;
The minimum water inlet temperature allowed is equivalent to 40°C.
The maximum and minimum temperature differentials for "Pump" and "Tank&Pump" set-ups are related to the perfor-
