The following assumes top-up temperature control is managed out by the solar controller.
Control Valve:
A control valve (2/3 way) is required to be fitted in the feed line from the primary heating
system.
This has to be sized for flow and pressure drop.
The control from the ‘Solar Station’ can only be used for on/off functions.
The voltage must be 230V and the maximum current must not exceed the output from the
'Solar Controller'.
Enable Output:
This is connected via a relay. Full primary heater control would then be managed by a
separate system
This enable output is used by Andrews Water Heaters if a boiler is supplied as part of the
SOLARflo package.
Primary Pump:
This is the same as the controller and voltage and currents have to be checked.
Full Boiler System:
See above. Please refer to technical details of boilers supplied and connection details.
