NEWROOF SENSOR
One of the new solar products about
to hit the market is the first solar hot
water wireless roof sensor by Kanitti.
The wireless sensor works with the new
Kanitti Drift2-w controller. Kanitti is an
Australian owned company. The Israeli
designed controller has been used with the
Chromagen system for many years now.
SYSTEM OVERHAUL
This job saw us work alongside an electrician to give his
Chromagen system a full service. After five years the pump
had packed it in. Being a typical electrician meant he had to
have the bells and whistles, including the ability to monitor
his solar production via the Internet and from his lounge
room. We installed a complete new pump station with the
Grundfos 15 20 CIl pump and RESOL BS/4 controller. We also
added a VBus adaptor, so we could connect the controller to
his computer, allowing him to monitor solar production and
change his settings either from his PC or remotely. We then
installed the smart display and mounted it in the kitchen.
As he chose a complete controller upgrade, a new 30mm
x ½” MI immersion sleeve from RESOL had to be installed
into the roof collector so the new roof sensor could be
installed. Once the solar side was taken care of it was
time to replace the element, thermostat and anode. You
can see by the photos that it was not a simple job but it
does highlight why a system needs to be serviced and have
anodes replaced.
