Control function
NOTE:
1. WP3 is always OFF during space cooling when DSW5-2 is OFF, in this situation cooling water circulation will not pass
through hydraulic separator.
2. WP1 and WP3 has 2 minutes or more of overrun after requiring OFF depending on outlet water temperature.
3. WP1 is always OFF when Boiler works as replacement source and heat pump stop working in Emergency operation
(referring to 10.1.3.2), HP Block operation (referring to10.9.5) or Boiler working mode of [Alternative] (referring to 10.6.).
(2) [O_mode(heating) ] is set as [OFF] (Space heating/cooling Thermo ON/OFF by room thermostats)

10.8.1.1.2 Hydraulic separator is Disabled
Only WP1 work to deliver water circulation When hydraulic separator is Disabled ([hsb] set as [Disabled]).
(1) [O_mode(heating)] is set as [ON] (Space heating/cooling Thermo ON/OFF by request of water outlet temperature on
Water Cycle 1 and Water Cycle 2).
Pumps control can be set to Standard or Economic mode. This conguration is set using DSW4 PIN5.
When PIN is OFF, pump is in Standard operation, pump is always in operation when space heating or cooling is enabled
(Switch ON), so in case of disable space heating or cooling (Switch OFF), pump stops operation.
When PIN is ON, pump is in Economic operation. This allows the pump to stop when space heating or cooling is Thermo
OFF (Demand OFF for space heating and cooling).
