Hi all, I just bought my first home, so I'm just learning about all the systems and I have a quick question about my HRV controlling humidity levels.
I just bought a new house that has a GreenTek HRV system installed (along with the a forced air gas furnace). There are two settings intermittant (only runs in high speed if wall control or humidistat is triggered) and continuous (runs all the time at low speed and high speed with wall control or humidistat is triggered). It is currently set to intermittant and there are push button controls in bathrooms/kitchen as well as dehumidistat with a manual knob.
Here's my problem. I currently have the humidistat set to about 45% RH (and it "clicks" when I turn it indicating that it actually is reading that value) but my store bought humidity meter is reading 58%. According to the manual, the dehumidistat should detect that the humidity is too high and start the HRV at high speed until the humidity level is correct. Just as a test, I set the humidistat to 30% and nothing happens - I expected the HRV to start going. I am noticing some condensation on the bottom inch or so of my windows, so I think the humidity is too high and given that the HRV doesn't start from the humidistat I'm taking the 58% to my actual humidity level.
Should the HRV be controlling the humidity from interm. mode, or do I need to have it in continous mode for that? Am I expecting the HRV to do something it is not intended to do?
The push buttons work fine and seem to bring down the humidity a little (~2%) when I run it for 20-40 minutes. Also, if it matters I am in southern Ontario and it's about -10c these days.
