I suppose that might be true at a stretch if you were doing space heating throughout the summer, but who does that? I would dig your heels in until yo...
@ashp-bobba Welcome to the forum. I would be interested to understand the reasoning behind your statements. What was your experimental set up? I would...
Can you explain the mechanism for this effect? Could it just be coincidental rather than causal? System volume may prevent short cycling, but there ar...

I am glad to hear that your consumption problem has resolved. On starting, it seems that the compressor ramps up to close to 100% and then modulates d...
There are 2 main display options on your wired remote controller. In both displays the current flow temperature and room temperature are shown on the ...
