(1) To test if the solar monitor plug is inserted
with correct polarity; release water from
the T&PR valve until the water temp in the
cylinder is < 75ºC. Switch off power for 5
seconds and then restore power. If the
LED flashes green (any combination) or is
solid red within the first 15 seconds from
restoring power, the solar monitor plug is
inserted the wrong way around.
(2) Check to ensure hot sensor plug and
socket behind upper electrical access
cover is also plugged in.
