Frequently Asked Questions
Q: The controller LCD and lights are flashing or resetting in the morning,
during the day or at the end of the day?
A: The Solatherm control unit is powered by the photovoltaic array. There is no
connection to mains/grid power required for standard operation. The controller
will only operate when sufficient energy is available from the sun. In low light,
such as in cloudy conditions, early in the morning or at the end of the day, it is
normal for the controller to flicker and dim and/or reset if there is inadequate
sunlight intensity to generate sufficient stable power for operation.
Q: My LCD show 0 Watts but the sun is out?
A:
1.
The water in the storage tank is up to temperature.
Dependant on the factory set temperature 60
0
C or 70
0
C.
2.
During periods of low light intensity such as, early morning, late evening or
in dark cloud the main array may not be able to produce the minimum
amount of power needed. The controller requires a stable 250 Watts to be
available when the element is energized to commence heating. The green
heating light will flick approximately every 25 seconds as the controller is
testing the amount of power available from the array.
Q: The heating light has been on all day but there is no hot water at the end
of the day?
A:
1. The hot water produced has been consumed during the day.
2. If the display is showing 0 Watts with the heating light on there may be a
fault with the element or the over temperature cut out. Please contact your
installer.
