Help with Fireplace Automation

[RHT]

Correct relay output but 4amps at 24v is way more then your probably 10ma at 3v.

Me personally I would wire a switch in series to be used as an E stop, you can break the circuit wherever you like to shutoff the fireplace.

Basically the switch would become automatic vs manual stop rather then on/off.

That makes sense, and I like that idea as well for safety reasons. I'll have to consider that one.

I know that 4A @ 24V is way more than (i think it was 120mA) @ 3V. I was concerned that 12V seemed to be listed as a minimum on the Elk. Can someone confirm that the Out3 dry contact relay on the elk will function correctly at 3V?

Hi

As a rule I do not automate anything that burns (liability issues you know)

However...I would locate a small dry contact in the same LV box that the firplace switch is in. The reason for this is emulate what the switch itself does at same distance as the switch as there may me current/noise limitations....so relay output of automation panel X triggers small (altronix?) low current relay which turns on the fireplace this relay must be wired for fail-off operation meaning if the relay goes bad it will not leave the fireplace running.

If the original switch is NC, wire the small relay in series, if the original switch is momentary or NO wire the relay in parallel.

In the programming add a LOT of redundant off commands on away/sleep/day activities just to be on the safe side.
