Installation
A possible way to install the SolaStat
TM
-Plus-ET is shown below. This
diagram is only to be used as a general guide and not all the required
components are shown. Each installation needs to be customised to suit its
situation. Always use best plumbing and electrical practices, and comply with
any regulatory requirements.
The roof, tank and inlet sensor will be wired to the collector, upper tank and
lower tank respectively. The power plug will connect to mains. After collector
and inlet temperature are measured, SolaStat
TM
-Plus-ET then decides if
turning on the pump to circulate the water is necessary to heat up the tank. It
also decides to turn on the energy transfer pump to circulate the stored water
to an external load when the tank reaches to the energy transfer
temperature. The arrow indicates the direction of the water flow.
