20 WSHN-XEE2 MF 10.2-120.2 M08R40A15-02
6.5 Configuration for 4-pipe system
Cooling requirement 100%, Heating requirement 0% (1)
In this condition, all the cooling capacity is released to the cooling side of the heat exchanger.
The maintenance of the cooling side set point is ensured through the modulation of the capacity steps.
All the heating capacity is dispersed on the source exchanger.
The pump control on the heating side may be activated or deactivated based on a schedule to keep water temperature under control.
Cooling requirement 0%, Heating requirement 100% (2)
In this condition all the heating capacity is released to the heating side of the heat exchanger.
The maintenance of the heating side set point is ensured through the modulation of the capacity steps.
All the cooling capacity is dispersed on the source exchanger.
Cooling capacity is not released on the cooling side: the cooling side pump control may be kept activated at a minimum or it may be activated
and deactivated based on a regular schedule to keep water temperature under control.
Cooling requirement 100%, Heating requirement 100% (3)
In this condition all the cooling capacity is released to the user side of the heat exchanger and all the heating capacity is released to the
heating side of the heat exchanger.
Maintenance of the heating side/cooling side set point is ensured through the modulation of the capacity steps, according to the operation
mode used (heating side in winter operation, cooling side in summer operation).
