Insulation Machine Remote Control Volumatic III

WORK IN PROGRESS-This is a DIY remote control for a Volumatic III insulation blowing machine. The remote system from RFhero is around $1000 and replacement remotes are upwards of $400. It’s a good product but the remotes only last a year or two and it’s a hassle trying to get them repaired. This hack uses an inexpensive 4 channel 433mhz transmitter and receiver, has several hundred yard range and the overall cost is around $30-50 depending what you have on hand, if you print your own enclosures & can scrounge bits of wire and screws.

receiver/remote/antenna, some magnets for securing the receiver mount, 1-2 feet of 12-3 electrical cord, (1) 3 Wire 15A 125V Grounding Locking Plug NEMA L5-15 Part # WBL515P and (1) IN4007 Diode, (4) M2 X 15mm stainless self-tapping screws. and (1) terminal for the ground wire.

You can probably scrounge the screws, diode and a few inches of small 20 gauge jumper wire that will get soldered between the relays and power in terminal on the relay board from an older appliance like a copier, etc.

Here also is a link for the remote relay/receiver on Aliexpress-

(note the two are identical but the Aliexpress relays were in a different order which makes it a little harder to copy my wiring)

Download the STL file from my Tinkercad link if you want/need to modify it for any reason-

Or Download from my Thingiverse link if you just want to print mine-

It has a lot of overhang.. I have a 45 degree belt printer so it’s not an issue but you may need to re-orient it or generate support for your print.

And here’s a link to have it printed. I’m ordering some in 9600 SLA resin that they say is good for electrical enclosures and very inexpensive-

First thing is to take the remote out of energy saving “ sleep mode”

do this by holding “A” & “C” buttons simultaneously for 6 seconds. This will need to be done every time the remote is in disuse for 10 minutes.

Next we need to erase the programming.

Hold the learn button for 6 seconds, the receiver light will flash 3X.

Now we need to program all the remote buttons to “latch mode”,

press the learn button 3X. Again the receiver will flash 3X.

Next we Pair the remote by pressing any key on the remote. The receiver will flash. Press a different key and now the remote light will flash and the receiver relay will click.

When you press a button in “latch mode” the relay will click once … if you press the same again you will hear nothing but if you press another you will hear a disengaging click. This is how you know it is programmed correctly.

If it was not successful start over by erasing The memory. The same goes if you need to Pair a new remote
