So had someone install my heat pump and solar geyser and a few issues came up.
The solar geyser is saying temperatures of 300 degrees on the tubes and 80 degrees in the geyser. Never had this issue before.
The heat pump is not switching off at 53 degrees anymore. Running to 60 degrees on the outlet, inlet stays at 36 degrees, and then giving an error and the high pressure switch opens. Once I manually stop the pump, outlet drops to 25 degrees minutes later.
Can anyone suggest a knowledgeable person in Cape town who can assist?
So I had a look at what he did and the manual on the SR81 and tried to figure it out.
From what I saw he had two sets of cables coming into t1 and t2, so one point measuring the solar geyser temp and one measuring the heat pump temp coming into the same T1, which to me appears as if it would cause confusion on the SR81 and heat pump displays as there are two different temperatures coming in?
and the SR2, The geyser temp, also had to cables, but this seems redundant as surely only one would be needed for both the heat pump and SR81 to read?
could this whole thing be that he should have wired each one to a different controller than trying to run them both from one controller?
I have a ITS 3.6 KW Heat pump and A ITS 10 tube solar collector.
Get hold of ITS themselves. They impressed me with their capability. https://itssolar.co.za/
Better still if it’s not new take the heat pump to them and get them to service it and get the low-down on all your questions…
NOC Plumbing saw this chat and will come assist, We have been going through everything over whatsapp videos and saw that they put the sensors in the wrong locations, all that is left to do is get a longer cable for the solar geyser sensor and then that should operate as it is meant to.
On the heat pump side all that is left to do is figure out the -7 degrees reading on the inlet water.
I also shocked myself on the geyser element…just for fun…guess they didn’t disconnect it like they said.
