suitable for R-410A heat pumps

this model maintains the critical 1/4-turn operation with internal rotation stops

It is factory-set to trigger at 75 degrees Fahrenheit and cannot be manually calibrated in the field

Techs often specify the 8221210003 for its robust housing and consistent repeatability in demanding environments

the perpendicular port orientation and MPL Dual 9375 design allow for a straightforward drop-in installation in tight blower compartments

Maxitrol TS121 Sensor Els PW 17895 suitable for R-410A heat pumpsFor veteran technicians servicing indirect fired make up air units, the Maxitrol TS121 discharge air temperature sensor is the critical component for maintaining a stable 55 90F terminal temperature range. Specifically engineered for integration with Selectra Series 20, 21, 30, and 31 modulation systems, this thermistor based sensor delivers a resistance of 4,500 ohms at 77F, providing the Maxitrol amplifier with the sub second response times required
