Wiring is straight forward as operation of the SOLARflo system is setup within the controller.
All the individual equipment needs wiring back into the controller. If there are multiple solar
fields, and/or multiple cylinders, extra sensors will need to be wired back to the controller (see
Fig 7).
If any outputs require volt free contacts or high loads please refer to the simple connections
above. A ‘Solar Station’ can have more than one contactor/relay.
THE CONTROLLER:
CONNECTIONS:
MAINS: Power Supply to Controller (230V 50Hz 4Amps)
If a contactor is supplied this will be pre-wired. A power supply should be connected into
the contactor.
OUTPUTS: A1-A6 are all 230V power outlets.
Outputs for standard systems – See controller instructions for other systems
A1: Solar Pump Power Supply This will be pre-wired.
A2-A4 outputs dependant on type of system and if multiple pumps are required
A5: Primary Heat Demand Output Wired on site if required (can be used for
other control)
A6: Destratification Pump. Wired on site.
Temperature Sensors:
T1: Collector Sensor: This will be wired using the wire fitted in the flexible pipe-
work (if supplied).
T2: Cylinder Solar Sensor.
T3-T5: Sensors for multiple vessels or sensors.
T6: Energy Measurement sensor if required (can only be used in conjunction with an
irradiation sensor)
T7: Primary Heated DHW sensor (Top sensor within twin coil cylinder or
temperature sensor in a second cylinder)
T8: Spare sensor for operation of other systems.
S1: Solar sensor, used for system start if T1 used for energy measurement.
D1: Flow meter for energy measurement. Uses T1 and T6
