Temperature High Limit Switch
As a safety device, either a surface mounted high temperature cut-off switch with manual reset, factory
set at 190° F, or an immersion high temperature cut-off switch with manual reset, factory set at 180° F,
may be provided. In the event of an over-temperature condition, the thermostat will disengage the
power from the back-up electric heating system. The high limit must be manually reset thereafter to
restart the heater.
