I have a 12 gal true steam with a vision pro IAQ t-stat. I have hooked it up according to the manual but it will not operate without a call for heat. It works fine when the t-stat is calling for heat but will not operate otherwise. I have tried to hook it up "independent" of fan control and the same issue happens. I am wondering if anyone can help with this problem.
Thanks,
matt

I have the t-stat set for 374=1 (true steam calls for fan).

UPDATE... Now the unit is not working at all, even with a call for heat.

UPDATE 2... I got it figured out. I got a bit confused. The fan was "on" but the system was "off" so there was no call for HUM. I feel like an idiot.
