Mitsubishi Ecodan PUHZ-SW120 & EHSC -VM20 on 3 phase power question
Mitsu PUHZ-SW120 & EHSC -VM20
Has anyone any access to power readings when at rest on a 3 phase ASHP?
I have just installed a Shelly 3EM 3 phase Power Monitor and am somewhat surprised that, at rest, the readings are unbalanced at:
Phase A=0; Phase B=11.31; Phase C=106
When producing heat, the readings are much more balanced.
What, if anything does that indicate?
