Brief description
The Daikin solar system is a thermal solar system for supplying hot water.
Operating mode
The high-performance flat solar panels EKSV26P and EKSH26P efficiently convert the sun's radiation into heat.The heat-transfer
medium in the solar panel system is a frost-proof water-glycol mixture, and heating water in the tank circulation system.
When the solar panels reach a usable temperature level the fluid in the solar panel circuit EKSGFL is pumped by the pump unit
EKSRDS1A and the plate heat exchanger of the solar connection kit EKSOLHWAV1. The circulation pump of the solar connection
kit EKSOLHWAV1 (solar panel circulation pump) simultaneously pumps the heating water in the storage tank charging circuit
through the plate heat exchanger where it takes up the heat given out by the solar panel circuit and transfers it to the hot water
via the storage charging heat exchanger.
Modular design
The system consists of several preassembled modules. Plug-in technology and a high degree of pre-assembly ensure fast and
simple installation.
Storage tank
Only the hot water storage tanks EKHWE*/ EKHWS* can be used for the Daikin solar system.
Electronic control
The fully electronic control system of the controller EKSR3PA ensures optimum utilisation of the solar heat (hot water generation)
and that all safety-relevant aspects are complied with. All parameters needed for trouble-free operation have been preset at
factory.

System components
Controller EKSR3PA
Construction, operating principle, commissioning, and operation of the storage tank are not described in this manual.
You will find detailed information on the storage tanks in their respective installation and operating manuals.
The Daikin solar system can only be operated with the air-water heat pump EKHBX*, the pump unit EKSRDS1A,
the controller EKSR3PA, the solar connection kit EKSOLHWAV1, the water-glycol mixture EKSGFL and the hot
water storage tanks EKHWE*/ EKHWS*.
Consists of:
– Controller EKSR3PA with storage temperature sensor,
return flow temperature sensor with sensor adapter,
connection plug solar panel temperature sensor, pump
connection and extension cable (P
S
), connection cable for
solar priority, connection cable 230V mains connection
(3 m)
– Accessory bag (4 fillister screws, 4 plugs,
2 locking screws)
– Documentation
