Pump timer

That would be true. Luckily I don't need mine anyway because I have a solar heating system that saves me a bundle

ok I did a little more research. The heater as stated by shadow man has a thermocouple. The pilot light heats two pieces of different metals twisted together creating a small electrical current, enough to operate the switch to turn on the heater. It also has a flow sensor to tell it when it can turn the heat on. Now, they problem is that I still need to turn off the heater about 10 minutes before the pump turns off. I do believe what I need is the intermatic timer that has a firemans switch (as mentioned) I just need to find a guy that has done spa/pool work... anyone know anybody north of toronto???

When I first looked at the online manual for your heater I scrolled to the part for IID heaters and thought it needed line voltage to operate. According to the schematic on page 31 (A-9) there are two options for remotely switching the heater. A 2 wire on and off, or a 3 wire option for the pool/spa/off switch. In either case, they are low voltage lines that have to be isolated from line voltages. I see Pentair makes automation controls that take this into account but they are probably overkill. Or at least more than you were thinking of spending.

Sorry I can't be of any more help. Good luck.
