Raypak 2100 pool heater won't heat, PRS and HL2 error codes.

Well, I replaced the pressure switch with no joy. I tried all 5 levels of pressure 1-5 and every wiring combination. Finally, I returned the new $70 pressure switch and took the 2 wires and tied them together (jumped them). Here's the only downside...If you run your pump in backwash, recirc, waste, or any mode that would cause water to bypass the heater it MUST BE OFF. Otherwise, let it ride. It's working great and I hope to go into October weather permitting.

What terminals on the Intermatic timer (Load/Line A and Load/Line B sides) do I wire the black, white, and red wires to? Raypak RP2100 capron digital natural gas heater.

You won't use all three wires from the heater, only the two required for the line voltage present inside the timer. Is the timer fed 115 or 230 VAC? You will want the heater on the line side to avoid the heaters power being interupted all the time causing you to have to always reset it. Just be sure to select the corect leads from the transformer based on voltage present.

Just got my pool repaster and need to turn on pump but for the last few years a big cloud of rust comes from the pool heater staining the pool. It's a Raypack heater, removing one of the panels looks like...

Rust is coming from the cast iron inlet/outlet header. Make sure your chemistry is balanced. If you winterize your pool, make sure the heater is completely drained. If you have an automatic chlorinator, make sure you have a chemical resistant check valve between the chlorinator and the heater. You can remove the inlet/outlet header and clean it before you start the system up. The copper heat exchanger should not emit any staining substances unless your pH is allowed to drop below 7.2, then you will see copper sulfate stains on your plaster (turquoise color).
