Looking for suggestions on something that I think should be pretty simple but I'm not quite wrapping my head around the "easy" answer...
Short request...
I just want to provide contact closure when a 120v switch is turned on, what's the easiest way to do that?
Ideally it would be through my Elk so that I can monitor it but I'd be fine with just a relay, etc. that would simply close an N/O connection when I turn on a specific light switch. Eventually I'll want 3-4 of these "inputs" (120v switch) to a single output (contact) which is why I eventually want it to run through the Elk.
More detail...
I've installed an HRV (whole house ventilation system) that has a high speed mode that can be triggered by closing a simple contact. I want to install a standard 120v humidity-sensing/timer switch in the bathroom that would both control a light above a shower and trigger the HRV to kick on. Once the timer switch times out (or shuts off due to low humidity threshold being reached), the contact is open and the HRV shuts off it's high speed mode.
Any simple way to do this that I'm missing? I'm thinking I need the OPPOSITE of an ELK 912 relay (ie sense 120v, trigger contact as opposed to sense 12v and open 120v path). I can't just wire the 120v load of the switch to the +/- of an ELK912 and connect the N/O+Com to the switch on the HRV, can I? I'm assuming the 120v would overload the relay that's expecting 12v, no? I ask because I have a bunch of 912s sitting around.
I also have an ISY + Insteon devices in my system that I can work with.
Thanks in advance for any thoughts!
