3.16. Customer Unit Configuration

Except for factory configurations, the client can custom the unit depending on his needs and options acquired. The allowed
modifications regard Unit Boost, Fan Boost, IO Ext Module, HMI Type, Pump Ctrl Type, SCM Address,
External Alarm, Costant Heating Capacity, SCM Number OF Units, Fan Silent Speed, Domestic Hot
Water.
All these customer configurations for the unit can be set in page [15].

3.17. Water Reversing Valve

The Water Reversing Valve(WRV), depending on the model (NC/NO), goes to exchange externally to the chiller the hot water
with the cold water or the other way around. to control the correct functioning of the valve it has been given the possibility to give
a delay to the opening in the passage between cold and hot water and the other way around.
