The T4398 Series Performance Thermostat:
Line Voltage Dual Diaphragm temperature Control Heat Wall Thermostat
The vast majority of line-voltage thermostats employ a bimetallic element to sense and control the heaters. This design works on the principle that different metals expand and contract at different rates as the heat and cool. These thermostats are cheap to make, but they tend to be inaccurate and to allow a very broad deadband. The deadband is the temperature range between when the thermostat turns the heaters on and when it turns them off. An old bimetallic thermostat could easily allow for an eight degree deadband or greater. That means that, if you set the thermostat for 68 degrees, it would not turn the heaters on until the temperature dropped to 64 degrees, and it would not turn the heaters off until the temperature reached 72 degrees. If you have baseboard heaters and you experience large changes in temperature while keeping a constant thermostat setting, the thermostat is causing the phenomenon.
Whereas the T4398 performance thermostats uses vapor-filled dual diaphragm temperature control, which tightens the comfort range with more accuracy, and can save up to 12% on your heating bill. These models include an industrial grade Micro Switch with extended life, and can replace most wall-mount line voltage thermostats and provides 2°F (1°C) sensitivity with minimum droop.
Features and Benefits:
Vapor-filled dual diaphragm temperature control tightens the comfort range provides 2°F (1°C) sensitivity with minimum droop.
Cover lock and temperature range stops (included) govern min/max temperature setting
Product Dimensions: 3.125W x 4.125H x 1.25D
UL and CSA Listed Rated at 22 amps. (5 kW at 277 VAC)
Factory sealed and calibrated
NOTE: Line voltage is very dangerous and the power to the heating system shouldbe shut off before changing the thermostat!
