The Honeywell T4398A1021 mechanical non-programmable thermostat provides precise line voltage control of resistive-rated electric heating equipment. It is a high performance electric heat thermostat.
High Temperature Sensitivity With Minimum Droop
The Honeywell T4398A1021 mechanical thermostat provides high-temperature sensitivity with minimum droop using a vapor-filled dual diaphragm sensing element.
Includes Plastic Mounting Base
The T4398A1021 non-programmable thermostat includes a rugged-engineered mounting base that has a captive mounting screw.
For quick installation, this thermostat features color-coded flyleads that are compatible with aluminum wire.
The micro-switch mechanism causes the heating circuit on temperature to fall.
