Raypak 005299B 10K Temperature Sensor Kit for RP2100 R185, R265, R335, R405 Electronic Ignition Pool Heaters (1993-1998)

This is the water temperature sensor for Raypak RP2100 heaters with electronic ignition (IID). It tells the heater's control board how warm the water is so the board can decide when to fire.

Fits these Raypak models: RP2100 R185, R265, R335 and R405 with electronic ignition (IID), built November 1993 through October 1998.

Raypak parts list name: Temperature Sensor IID Units. On these heaters it is listed in the controls group with P.C. board 005241F.

Good to know: Later RP2100 heaters take other sensors: the R185A to R405A (1998 to 2003) list 006701F, and the R185B to R405B (2003 to 2004) and digital 206A to 406A list 009577F. Millivolt RP2100 heaters use a mechanical thermostat (003346F) in place of this sensor. Check the model number and build date on the rating plate before ordering; the three sensors are listed for different generations.
