This Light Duty Line Voltage Heating-Cooling Thermostat is

designed for controlling fan motors, circulator motors, contactors,

motor starters, valves, etc. To provide greater room comfort, the

thermostat is equipped with ﬁxed anticipators.

Two dial stops are supplied, which may be used for making a

maximum or minimum setting, a limited temperature range or

a locked dial setting. (See parts package).

The temperature may be set anywhere between 36° and 90°F

or 2° and 32°C by turning knob to the desired temperature on

the dial.

Positive off or system selection can be obtained by using a

switching sub-base. Optional heating and cooling sub-base

S29-21 is available.

CAUTION

When thermostat is set below 40°F or 5°C, damage to

the building and/or contents may result due to freezing.

This is possible due to factory calibration tolerances,

thermostat location and operating characteristics of

the heating equipment.

SELECTING LOCATION The proper location of the room thermostat is most important to insure that it will provide a comfortable home temperature. Observe the following general rules when selecting a location: 1. Locate it about 5 ft. above the floor. 2. Install it on a partitioning wall, not on an outside wall. 3. Never expose it to direct light from lamps, sun, fireplaces or any temperature radiating equipment. 4. Avoid locations close to doors that lead outside, windows, or adjoining outside walls. 5.
