I Just bought a new pentair mastertemp 200k btu low nox natural gas heater. I had a pro hook up gas and pool plumbing. I ran conduit and electrical to 20amp 120v circuit breaker directly. I also ran 16awg 2 wire from the heater to Jandy JEP-R controller. The JEP-R has 4 inputs and a com. The heater has fireman's switch loop (fuse wire) and on the control board a 3 wire pool, spa, com terminal block. Heater lights up when loop is connected. When I take off fuse wire loop from fireman's switch on heater and replace with 2 wire spade connection and terminal block to input 4 and com on JEP-R. I turn on the remote 4 (input 4 wiring) because it is programmed to run for 30 minutes after turning off control. Heater does not light up at all. I thought it was a simple contact closure. When I simply touch the wires together to close the contact, the heater lights up. Am I missing something? It reads in the manual that it is a contact closure on the JEP-R. I only have a pool no spa so I could wire the 2 wires to com/pool on the control board but I think that requires 24v which the the Jandy does not put out unless I am mistaken. I understand relays and contact closures...this is not behaving that way. Sorry for the long post. The long and short of it, I need to know how to wire up the Jandy JEP-R to the Pentair Mastertemp 460730 model so I can turn the heater on with the JEP-R.
Thank you!
Thank you!
