If your gas fireplace remote has stopped working, this Skytech receiver box might be the simple fix you need. It's a direct replacement for the 1001 Series fireplace remote controls, specifically designed for millivolt gas fireplaces. The unit operates on 4 AA batteries (included), so no electrical wiring required - just connect the two low voltage thermostat wires to the TH and TH/TP terminals on your gas valve. It features a manual slider switch with Off/Remote/On positions, giving you control even if you lose the remote. The Learn button lets you sync it with your existing Skytech remote control easily. Compatible with several models including SKY-1001-A, SKY-1001T/LCD-A, SKY-1001D-A, SKY-TM/R-2A, and SKY-1001TH-A. Important note - this is for millivolt gas valves only and acts as a dry contact switch (it doesn't output voltage). Installation is pretty straightforward if you're comfortable with basic wiring, but if you're unsure, hiring a professional is always smart when dealing with gas appliances. Much more affordable than replacing your entire fireplace system, and often solves the common issue of remote/receiver communication failures. Gets your fireplace back to convenient wireless operation without the hassle.
