These room thermostats are especially designed for
controlling heating equipment operating on line voltage
with heavy electrical loads. They are suitable for opera-
tion of unit heaters, boilers, furnaces, electric heaters,
etc., or any similar application requiring a heavy duty room
thermostat.

These thermostats are ideal for use in public places where
it is desirable to have a tamper-proof control to prevent
unauthorized temperature adjustment.

The dial is inside the special locked case which requires
use of a special wrench to remove case from mounting
plate to change temperature setting.

PRECAUTIONS

THESE CONTROLS MUST BE INSTALLED BY A
QUALIFIED INSTALLER.

Do not exceed the specification ratings.

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 calibrate this control will void the White-
Rodgers warranty.

To prevent electrical shock and/or equipment
damage, disconnect electric power to system at
main fuse or circuit breaker box until installation
is complete.

CAUTION

Do not use on circuits exceeding specified volt-
ages. Higher voltages will damage control and
could cause shock or fire hazard.

WARNING

INSTALLATION

The proper location of a heavy duty room thermostat is
very important to assure good performance. The following
general rules will help in determining the proper location:

1. Make sure that it is in a place where air circulates

around it freely. This is important.

2. Never install it on or near an outside wall.

3. Keep it away from windows or doors.

4. Don’t locate it too close to a strong light or any other

false source of heat such as direct sunlight, steam
lines, etc.

5. Mount it on a post or a partitioning wall, but make sure

that there are no pipes or duct work in that wall or
directly behind it.

6. If the electrical conduit leads into a cooler or a warmer

room, plug up the space around the wires in the conduit
with rock wool.
