Hi, I use Braeburn 5400 stat connected to my conventional 80% HVAC. I am planning to have a whole house humidifier installed. Doing some research, I found most of them come with their own stat, etc. Looking at my 5400 literature, I find some great options (since I also have the outdoor sensor installed) which i want to utilize. Wondering if you folks can help me understand a few things.
1. In installation manual, option #22 - Dehumidification fan speed control. Explanation given is: Feature accommodates either a normally open relay or a normally closed relay. Selects between Dehumidiﬁcation fan speed limiting off (NO), or on: D output normally active (NA) and D output normally inactive (NI).
What exactly should I be selecting? I've understood that during cooling periods, if it's high humid, stat will run cooling for a longer time and effectively try to lower the humidity levels, etc. but nevertheless don't understand what the above means and what should be the settings.
I might be installing a humidifier pretty soon. My furnace provides a 110V humidifier tap, activated when there's a heating call.
Question a: I would like to avoid installing the humidifier's own stat but rely on the settings of the Braeburn stat. Effectively, if the humidifier is connected into the 110V furnace tap can I assume that as and when my 5400 stat detects a need for humidification, it'll call the furnace to start, which in turn activates the humidifier, thus effectively I am controlling my home humidification completely using my 5400 without having to install the humidifier's own humistat. I also thus utilize some features provided by my 5400 using my outdoor sensor, which I have.
Question b: However, I also do see in 5400, there's a humidifier connection available. I wanted to know what's the use of that in conjunction to what I stated above?
Note: I am not planning to do a DIY on humidifier. However, it'll be terrific if I can know of the feasibility beforehand and how the wiring setup operates. I am getting some quotes, etc. from reputed HVAC professionals but some have stated evap, some drum, some fan-powered, some steam. I am on a tight budget. Against all that's above, if I know beforehand how to achieve the wiring along with pros and cons of humidifier, I can have a good discussion. I am in NJ, USA and in a small 1500 sq. ft 2 storied townhouse, built around 1960.
