Cool_WP2 Cooling operation for WP2
(1) Any room thermostat is available on Water Cycle 1, then WPc1 is demanded operation by room thermostats on Water
Cycle 1.

NOTE:
1. WPc1 is always OFF during space cooling when [Cool_WP2] is [Disabled], in this situation cooling water circulation will
not pass through Water Cycle 1.
2. WPc1 has 2 minutes or more of overrun after requiring OFF depending on outlet water temperature.
3. WPc1 will continue running to use storage heat capacity in hydraulic separator to heat up Water Cycle 1 during heat
pump DHW operation when Any room thermostat on Cycle 1 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. WPc1 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 1, then WPc1 is demanded operation by Water Cycle 1.
