Fig. 07: Solar Control Connections

Installation - Solar

Connection To Solar Primary Circuit

The lower (solar) coil of the S

OLAR

 cylinder must be 

connected to a fully pumped solar primary circuit. The 

connections are suitable for 22mm copper pipe direct 

to the compression fittings provided. The connections 

are also threaded 3/4” BSP male parallel should BSP 

be required. 

The solar primary circuit should have its own dedicated 

circulating pump and safety controls which must be 

installed as per the manufacturer’s instructions.

Control of Solar Primary Circuit

Temperature control of the S

OLAR

 cylinder must be 

carried out using a suitable proprietory solar controller/

programmer. The cylinder temperature sensing probe 

(supplied  with  the  solar  controller)  should  be  fully 

inserted with the thermal cut-out probe into the pocket 

provided on the SOLAR

  cylinder.The  cable  must 

be  secured  using  the  cable  clamps  on  the  controls 

housing.

Connection  to  the  solar  controller  should  be  in 

accordance  with  the  manufacturers  instructions. 

The solar controller should be programmed to give a 

cylinder temperature of approximately 60°C (maximum 

70°C).

SOLAR CONTROLLER

The solar controller and solar primary circulation 

pump must be wired via the over-temperature cut-out 

mounted in the lower solar controls housing. This will 

ensure that the heat input to the solar coil is interrupted 

in the event of the cylinder over-heating (see Fig. 07 

below). There must also be suitable check (non-return) 

valves installed in the solar primary flow and return to 

prevent the possibility of any thermo-syphoning if the 

solar circulation is stopped.
