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...
With your 2091/2092 settings, the heat pump will only cycle off if your 3rd party thermostat is no longer calling for heat. If your home is warm, t...
Those settings exclude frequent cycling as the cause of poor efficiency. With 2091/2092 set to 'Use(Signal only ON/OFF)', FSV 2093 is inactive, so it ...
@raiph I apologise for my incorrect assumption. A PWM pump should maintain your delta T, so I am not clear why you are experiencing problems with a lo...
@raiph You seem to want a Delta T of 5, but your water pump has a fixed speed / flow rate which is currently 15 l/min. Your heat output is determined ...
@dinhp I will try and upload an audio file as it is difficult to describe how it sounds. The noise level will vary depending on how hard the heat pump...
@dinhp Thanks for the extra info. Your COP of 2.49 for today is not great if OAT is 9C, although it was probably colder overnight. Does this include a...
@dinhp I have a 12kW Gen 6 Samsung and your weather compensation settings look fine. Mine are -5/50 and 10/30, so at 7C OAT our flow temperatures shou...
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 ...
