Product details
The Raypak 600892B is the 135 deg F hi-limit control, a high limit automatic gas shut-off in a red epoxy body. It is the genuine Raypak part.
What it protects against
The hi-limit is a safety control, not a comfort one. It reads the temperature of the water on its way out of the heater, and if that water climbs past the rating on the control it cuts the gas. That is what stands between a heater with a flow problem and a heat exchanger boiled dry. The rating is stamped into the part for a reason, so a replacement must match: fitting a higher rated control removes the protection you are paying for.
Which heaters
Raypak names this control for the model 268 and 408 atmospheric professional pool heater. The same part number also turns up on the Versa 155 and 185 through 405 series, the RP2100 R185 through R405 heaters, and the 206A through 406A and 207A through 407A heaters, so check 600892B against the parts list for your own heater before you order.
Before you replace it
A hi-limit that trips repeatedly is usually reporting a real problem: a dirty filter, a closed valve, a failing pump or a bypass out of adjustment. Chase the flow first. Replace the control when you have confirmed the control itself has failed.
