Time & Differential Temperature System Control Unit.
The microprocessor driven control unit gives the user complete control of system
parameters and ensures that you will always have hot water.
The units displays water temperatures at the bottom and top of the tank as well
as the manifold
temperature, it also controls the pump to ensure optimum benefit
is derived from the Suns power.
User definable time periods where heating may be supplemented electrically
should target
temperatures not have been reached ensure that hot water is always
available in the event of
reduced solar contribution due to rainy days for example.
Systems offered without a time and temperature based control unit cannot deliver
meaningful savings
in electricity consumption and should be avoided.
The unit provides frost protection electronically, should the manifold
temperature fall too low at night.
A battery-backed option is available
to keep the controller operating in the event of power failures.
In addition the control unit provides a fail-safe over temperature protection
system to prevent overheating
which can occur in directly coupled
or Thermosyphon systems.
