I have a bryant Evulation heating system. IMy desire is to connect a Honeywell Steam hunidifier to the system and let the Evulation control the humidty.


Will require a isolation relay to connect.

I would install a isloation relay just based on the fact that the steamer is a resistance load usually with a snap action contactor. The Bryant system you chose in top of the line so do not skimp on install materials. Keep as much load and spurious harmonics off the circuit board as possible.
