NOTICE
• 2455RM/2450CM thermostats are intended as a manual reset control. They are not to be used on applications where a limit
thermostat is required unless back-up protection is provided. Units have been tested by UL for 1,000 cycles under load,
5,000 cycles no load, and are not considered as limit devices.
• This range of thermostats has an automatic reset function with manual override function.
• Reset pin operation should not be performed above 70% of set point temperature.
