Control function
10.8.1.2
WP2 control
WP2 is used only in case a secondary Water Cycle for space heating or space cooling is used. It ensures water circulation
at Water Cycle 2. The mixing station is controlled using the indoor unit by means of a mixing valve / additional pump (WP2)/
additional water sensor (Tow2).
The conguration of this option should be done through the master controller.

NOTE:
1. WP2 is always OFF during space cooling when [Cool_WP2] is [Disabled], in this situation cooling water circulation will
not pass through Water Cycle 2.
2. WP2 has 2 minutes or more of overrun after requiring OFF depending on outlet water temperature.
3. WP2 will continue running to use storage heat capacity in hydraulic separator to heat up Water Cycle 2 during heat pump
DHW operation when Any room thermostat on Cycle 2 is Thermo ON and [Point of DHW & SWP] set as [Before Hydr S]
which means Point of 3-way valve for DHW and 3-way valve for swimming pool is before hydraulic separator. Refer to
10.1.
4. WP2 will stop running during heat pump DHW operation if [Point of DHW & SWP] set as [After Hydr S] which means
Point of 3-way valve for DHW and 3-way valve for swimming pool is after hydraulic separator. Refer to 10.1.
(2) None room thermostat is available on Water Cycle 2, then WP2 is demanded operation by Water Cycle 2.
