FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
This control is a dual-function control having a tempera-
ture control in series with a high-limit control.
The temperature control is a normally closed SPST switch
which opens on a rise in temperature and will control one
heating element.
THIS CONTROL MUST BE INSTALLED BY A QUALI-
FIED INSTALLER.
All wiring must conform to local and national electrical
codes and ordinances.
This control is a precision instrument, and should be
handled carefully. Rough handling or distorting compo-
nents could cause the control to malfunction.
This control has been accurately calibrated at the factory.
Any attempt to re-calibrate this control will void the White-
Rodgers warranty.
WARNING
!
Do not use on circuits exceeding specified volt-
ages. Higher voltages will damage control and
could cause shock or fire hazard.
If in doubt about whether your wiring is millivolt,
low or line voltage, have it inspected by a qualified
heating and air conditioning contractor or a li-
censed electrician.

The limit control is a normally closed SPST switch which
opens on a rise in temperature to limit the maximum
allowable temperature. It has manual reset.
