Hi, Ray - this may not be in the right section, but answering in hopes of helping out. pentaire has several generations of communications protocols from what I've read. Depending on how old yours may be, buying a new receiver may not match the transmitter/remote, so it may not work. Listed on the back of the remote should be a revision number that you can google to find the communications protocol in use. Buying a matching receiver should work, hut at higher cost. Good luck,
