Maybe I can explain my problem further.
I have an Acumen Tech Fireplace Remote (Acumen RCK-M Fireplace Remote Control with Flame Adjustment for Maxitrol Gas Valves)
This utilizes a ON-Up, OFF-Down two button function.
For whatever reason, the receiver/valve picks up the Bond signal but the repeat rate from the Bond is too rapid for the receiver to respond right away. It takes about 20 seconds of continuous hold on the physical remote to move the valve to a reasonable position for a fire. Even if I set the reps to 1000 because of some timeout feature in the Bond the valve only advances about 30% of its nominal range. It does not matter if the number of reps is 200 or 1000 as the Bond stops sending the signal after about 10 sec. I am hence forced to press the On button on the Bond x 3 to advance the valve to a usable position. The 600ms doesn’t seem to be the limiting factor.
I think I need a better explanation of your “Long answer”. How do I make the whole signal last that 0.6 sec.
