Hello all—
I’ve read through many of the “wiring” and “two-wire conversion” topics, and don’t quite see my particular issue (I know, I’m “that guy”).
I’m installing an Insteon 2441TH to my Harman Advance pellet stove. Harman and their forums have descriptions on how to hook up a smart TStat. The basic idea is to “break” the connection with the onboard room-sensing thermostat (on the pellet stove) thereby tricking the stove into a false error mode. When heat is called for from the Smart Tstat at the R&W terminals, this completes the connection and the pellet stove will be satisfied and fire up.
One little addition is I’m powering the Insteon with a 24v transformer plugged into the wall.
SO... The Insteon is successfully powered when I hook up the transformer to the 24Com and 24R connections. The pellet stove wires are supposed to be connected to the R (24R??) and W connections (so I have two wires going into the 24R???).
This combo almost works: stove starts with the appropriate error mode, sits idle. When heat is called for from the Insteon, the error mode goes away and the stove fires up. Great, BUT— the stove won’t go back into error mode when I tell the Insteon “no heat.”
So I can turn the stove ON remotely, but can’t turn it back off again. That’s sort of ok for my application, since I’m really just using it to pre-heat a vacation house during the drive up there, but it makes me think my connections are incorrect. So far, the only way I can get the stove to go back into error mode is to depower the Insteon stat and start fresh. Definitely not something I feel I ought to do on a regular basis.
Things I’ve considered: cycle time for furnaces (I waited at least 20 minutes for the Insteon/stove to finally send the “kill” signal, but it never arrived). Can I adjust the cycle time just to be sure?
Thanks all.
