Whole house humidifier questions.
Whole house humidifier questions.
(OP)
I have a forced air funace and a GreenTek air to air exchanger in my house and want to install a whole house humidifer, I'm thinking the Honeywell HE260 Bypass Flow Through Humidifier.
My question is this: The air to air exchanger is controlled by a humidistat mounted by the thermostat, is there a way to control both the humidifier and air to air exchanger from the same humidistat?
Or if I have to install a new humidistat for the humidifier will it and the air to air exchanger fight to add/remove moisture? I don't want to create an issue where they are both always running becuase they counteract eachother.
Sorry if this is dumb question, appreciate any insight you may have.

That's my opinion.

To make this work right, you'd really want the HX operation to look at the OA temp; if below 50°F or above 80°F, run heat recovery. If it wants to get fancy and run an enthalpy comparison, do it during summer but not winter.
Your humidifier should control independently of the heat exchange function and should operate based on humidity of air going back to the heat exchanger (prior to it), but be limited by a separate discharge air high limit humidistat located in the supply duct, downstream of the humidifier, that prevents excessive humidification/condensation (typ. set to about 85% RH). I'd suggest a set point limit of about 30% RH in the exhaust air, unless you have really good building envelope, modern double pane windows, up-to-date walls/insulation, etc...

Typically residential activities (cooking, bathing... breathing) add a fair bit of moisture to the house.
