Mark Description
AEH Auxiliary electric heater in water circulation
DHW EH DHW Electric Heater in DHW tank
WP1 Water Pump1 between plate exchanger and hydraulic separator /installation
WP2 Water Pump2 used only on Water Cycle 2
WPc1 Water Pump c1 used only on Water Cycle 1
WP3 Water Pump3 from hydraulic separator to the distribution circuit
Vmix mixing valve to achieve a second temperature control on Water Cycle 2
3WV Cooling 3-way valve for cooling diverting to cooling fan coils
3WV DHW 3-way valve for DHW diverting to the sanitary DHW tank inner coil
3WV SWP 3-way valve for swimming pool diverting to the swimming pool heat exchanger
ACT1- ACT7 room actuator to achieve room temperature control
Cycle_1_room1…4 Room thermostat1…4 set on Water Cycle 1
Cycle_2_room1…4 Room thermostat1…4 set on Water Cycle 2
Room_amb1…7 Room temperature detected by auxiliary sensor
wired1…2 wired room controller1…2
Tiw Measured inlet water temperature
Tow Measured outlet water temperature
Tow2 Water Cycle 2 outlet water temperature
Tow3 Hot water temperature detection of hydraulic separator
TDHW DHW water temperature of DHW tank
Tswp Measured swimming pool water temperature
Tsolar Measured Hot water temperature of solar panels
NOTE
1. Automatic Bypass Valve or equivalent Bypass replacement should be tted after the pump in water circulation to prevent
pump pressure from climbing signicantly and ensure adequate ow.
(3) For Integra Unit with DHW tank combination, [Point of DHW & SWP] is [Before Hydr S] as default setting. The extra WP1
must be installed at beginning of water circulation just after 3WV DHW to o󰀨er total hydraulic head for all water circulation of
SWP/Space Heating/ Space Cooling.
