KERS 25 Evo Heat Recovery Ventilation - Installation problem

mspirko

Hello,

I bought KERS 25 Evo heat recovery system and went on to install it myself. Everything was OK until I tried to connect a power cable to the unit. Documentation instructs to connect the power cable to the "input" side of the terminal strip marked with "L" = line and "N" = neutral. Problem is that I don't have "L" and "N" labels. My unit comes with numbers 1 2 3 4 5 6. I manage to deduce that "input" 1 on a terminal strip is "L" because the "output" cable goes to the power switch. I tried the continuity test on all "input" ports with no luck. I can't get a confirmation that the circuit is closed on the multimeter.

Please let me know if you ever installed this unit and how it suppose to be wired.

Maybe try the Electrical forum?

I can confirm that port 1 is "L" = line and port 2 is "N" = neutral. The other 3 ports are for connecting KERS in serial.

Tried research these a bit and came on your thread, what I can see they've been some "debunk" over in the US of these that they don't work , as in strong enough to remove enough CFM etc etc. What are your findings after having it? Looking to get a few for an old cottage that has 0 vents today and don't want the attic converted into a spider web of ducting :D

Where did you get that one? Have been looking around the various China offerings...
