•
‘Setup Monitoring communication’
takes you to a page to register
your controller with the Heliodyne Monitoring Service. Once you
are registered with the service, this link is hidden. See section 5.
•
‘test remote Monitoring communication’
will perform a test to see
if the controller can contact the Heliodyne remote server.
•
‘Download System Sensor and Energy Data’
opens a new page
which displays all the current saved history data in the controller,
about 1 month’s worth of sensor and energy data.
•
‘relay and variable Speed Output control Panel’
opens a new
page within which one can manually turn on and off relays and
set pump speeds.
•
‘Update Software version’
directs you to a page to begin the
software update process. See Section 6.

The limit Value T2, or the average of T2 & T3 if installed, at which the
solar relay will turn OFF even with a satisfactory differential. NOT TO BE
