v0.8.3 and Ecobee

Recommended Posts

I use the ecobee3 humidification and dehumidification setpoints in ISY to turn my humifier on and off. ISY reads them into variables and then reads the current humidity to regulate the switching on/off of my floor humidifier. io_guy did a lot of work to make this work.

 

The ecobee3 is not wired to a central humidifier. I have no room to add a furnace unit as I was told, when I built my house, I wouldn't need one. Big mistake. NodeLink and ISY saved the day for me.

Hi io_guy, thanks for the reply! I️ would use the automatic, but I’m not sure the Ecobee takes into account maximum inside humidity? I️ have a chart that I️ follow according to outside temp. If the Ecobee does accomodate, than there wouldn’t really be need to set the humidification point.

 

Larry, yes you can read the humidity but I️ connected my Ecobee to the humidifier.

 

Thanks!

ecobee3 and ecobee4 have frost control based on outside weather built into the stats. There is a window efficiency setting in the stats with descriptions for each setting.

 

I never use it. I have sealed vapour barrier around my house wall to prevent moisture damage.

 

I humdify between 38 and 42 % all year around. This helps with dry skin, sore throats and keep molding to a minimum. At this level of humidity my double pane windows just sweat slightly when the outside temps hit about -10 to -15 C

When I was running an Insteon thermostat, I was using the RelayLinc to control the humidifier according to the following chart (which is pretty much the universal standard):

 

 

Outside Temperature    Inside Humidity

20º to 40ºF                    Not over 40%

10º to 20ºF                    Not over 35%

0º to 10ºF                      Not over 30%

-10º to   0ºF                   Not over 25%

-20º to –10ºF                 Not over 20%

-20ºF or below               Not over 15%

 

With the Ecobee, it looks like they recommend 36% as the humidity along with the adjustments to window efficiency and you can turn on the frost preventer. Do we know if their program follows this chart?

By checking the ecobee3 I have sitting on my desk right now I find.

 

Window  =   RHMAX  @ -11c outside and 22c inside

 

7    =   50%

6    =   49%

5   =    42%

4   =   35%

3   =   28%

2   =   21%

1   =    15%

 

I find these attempt at frost control somewhat based on a lot of guessing. If you have good air circulation you don't get much condensation on your windows under any conditions.

I  have PVC windows so a little dew doesn't bother me and my confort is more important than my windows. This may be different if I had a house without vapour barrier and outside foam insulation. Then you can get structural damage, insulation loss through ice bridging inside the insulation and mold throughout the construction

Interesting, so it looks like it adjusts in the same manner. You just have to get the window efficiency correct for the house.

If I had wooden frame windows I might worry about the max humidity  curve.

 

My health and comfort is more important than saving cleaning the lint condensed on window pane gaskets  every spring. When the pane condensation gets bad, I raise my blinds off the bottom of the window sill about an inch, so air can circulate behind the blinds, and/or run my ceiling fan more often. That only happens maybe a few days each winter, when temps get down to -20 to -30c. Mine never freeze.
