of resistance-rated electric baseboard heating equipment with

2°F (1°C), regardless of the load of the baseboard heater.

The vapor-filled dual diaphragm sensing element is more
M5799
sensitive to temperature changes than a bimetal sensor. This
accuracy, usually associated with low voltage thermostats, is
now available for line voltage control.
Electric heat thermostats are often affected by the heat
generated in the control. Temperature control points may vary
or droop 2° to 4°F (1° to 3°C) depending on the load demand;
however, temperature settings are adjusted to provide offset.
The T4098 provides precise control with minimum droop. This
allows better control of room temperatures from day-to-night
and season-to-season while saving energy.

Make sure that all wiring connections are secure
before beginning checkout.
Move the thermostat setting knob clockwise until the
switch makes (clicking sound); the electric heater starts.
Move the setting knob fully counterclockwise; the switch
breaks and the electric heater stops.
Allow the thermostat to operate for several hours to
determine the appropriate temperature setting. Adjust
the setting as necessary.
