PRE-INSTALLATION
Inspection
Inspect the carton for damage. If damaged, notify the
appropriate carrier immediately. If undamaged, open the
carton and inspect the device for obvious damage. Return
damaged products.
Required Installation Items
• Wiring diagram
• Tools (not provided):
Digital volt-ohm meter (DVM)
Room temperature thermometer in °F or °C
Appropriate screwdriver(s) for cover, terminals and
mounting screws
Appropriate drill and drill bit for mounting screws
• Appropriate accessories
INSTALLATION
4. Hook thermostat on top of mounting plate and swing down into place.
5. Tighten thermostat mounting screw.
Caution:
1. Installer must be a qualified, experienced technician.
2. Disconnect power supply before installation to prevent electrical shock and equipment damage.
3. Make all connections in accordance with electrical wiring diagrams, and in compliance with national and local codes. Use copper conductors only.
4. Do not exceed ratings of the device.
5. Avoid locations where excessive moisture, corrosive fumes or vibrations are present.
Mounting
LOCATION
Locate the thermostat on a wall where it will be exposed to
unrestricted air circulation, at a minimum of 15 ft./min. (4.6
m/min.), which represents the average temperature of the
sensed space. Normally, the thermostat is located 5-1/2 to
6-1/3 ft. (1.7 to 2.0 m) from floor level. The thermostat is
designed for service in any normally encountered human
environment.
Caution: Do not locate the thermostat near sources of heat
or cold, such as lamps, sunlight, or concealed ducts or pipes.
Avoid locations where excessive vibration, moisture,
corrosive fumes or vapors are present. NEMA Type 1 covers
are intended to provide a degree of protection against contact
with the enclosed equipment.

OPTIONS
Tamper Resistant Cover
Replace slotted cover screw with Allen screw.
Concealed Setpoint
Knurled Dial Removal
See Figure 3.
1. Remove thermostat cover.
2. Secure the setpoint dial with hand so that the dial will not rotate.
3. Place needle nose pliers at knurled ring of the setpoint dial at the points where the knurled ring is attached to the setpoint dial.
4. Twist the pliers at each knurled ring attachment point until the entire knurled ring of the setpoint dial is removed.
PROCEDURE
1. Pull all wires.
2. Fasten mounting plate to box or wall.
3. Make electrical connections to thermostat screw type
terminals. Make all connections in accordance with the
job wiring diagram and in compliance with national and
local electrical codes. Class I wiring is required unless all
circuits to contacts are powered from a Class II source.
(See Figures 7 through 9 for typical wiring diagrams.)

Dial Stop Pin Insertion - Included with Mounting Plate
See Figure 4.
1. Remove thermostat cover.
2. Secure the setpoint dial with hand so that the dial will not rotate.
3. Place a dial stop pin in the jaws of a needle nose pliers.
4. Insert the dial stop pin in the appropriate hole on either (or both) side(s) of the setpoint dial to restrict dial rotation.
Figure-4 Dial Stop Pin Insertion.
Cover Insert Installation
See Figure 5.
1. Select appropriate cover insert.
Note: If blank insert is used, the knurled ring must be
removed from the setpoint dial. See Knurled Dial Removal
above. Also, remove dial window by sliding and /or pressing
window from front of cover.
2. Remove protective backing and protective skin on face of cover insert.
3. Press insert uniformly on thermostat with logo in lower left-hand corner.
Figure-5 Cover Insert Installation.
CHECKOUT
After installing the thermostat, make an initial check of the
switching action. Verify the switch action by watching the
switch contacts, or by using a volt-ohm meter between the
proper sides of the switch, or observing the controlled device.
1. Move the setpoint dial to a temperature above ambient. On TP-101 1 the “R” cont act will make. On TP-103 1 th e “B” contact will make.
2. Turn the setpoint dial to temperature below ambient. On TP-1011 the “B” contact will make. On TP-1031 the “R” contact will make.
THEORY OF OPERATION
The fast responding temperature sensitive element in the
thermostat makes and breaks the control contacts as required
to maintain room temperature. A proportional feedback
magnet exerts a compensating force on the element in direct
relation to the position of the controlled actuator. Thus, the
resultant control action is based on both room temperature
variations and changes in actuator position [the latter being
indicative of increases or decreases in the amount of heat (or
cooling) that is being supplied to the room].
CALIBRATION
All thermostats are calibrated at the factory and normally will
not require any such attention. Due to self-heat from internal
components, power to the thermostat must be on for at least
one hour before checking calibration. If recalibration is
necessary for any reason, proceed as follows:
1. Set adjusting dial to approximately 2°F below the actual room temperature as determined by an accurate thermometer near the thermostat.
2. Remove thermostat cover (loosen cover mounting screw, swing cover at bottom up and away from the wall, then unhook at top). Be careful not to affect the bimetal element with heat from your hands or breath.
3. Remove contact cover.
4. Allow controlled actuator to run to either end of travel.
Actuator position may be determined by means of a DC
voltmeter placed across the proportional magnet coil at
test terminals. The DC voltage across this coil varies from
14 to 28 volts as the actuator travels between limits.
Mid-position is 21 Vdc.
5. If contact blade is made to the left (R) contact, use TOOL-11 (3/16" open end wrench) and very slowly turn the calibration screw out (CCW) until blade just makes to right (B) contact.
Controlled actuator will now run toward the mid-position;
when it reaches this point (21 volts across coil), slowly
turn calibration screw in (CW) until right contact just
breaks (actuator stops). (Each complete turn of the
screw changes the calibration about 30°.)
Thermostat is properly calibrated when contact blade
floats (does not make either contact with 21 volts across
the coil) at approximately 1 to 2°F below actual room
temperature (by dial) with the cover removed.
6. If contact blade is originally made to the right (B) contact, turn calibration screw slowly in (CW) until right contact just breaks (actuator stops).
Controlled actuator will now run toward mid-position (21
Vdc across coil); when it reaches this point, slowly back
calibration screw out (CCW) until blade just makes the
left (R) contact.
Thermostat is now properly calibrated.

Note: Correct contact gap is 0.003. It may be checked with a
feeler gauge.
7. Replace contact cover and thermostat cover; then recheck calibration about 30 minutes later.
MAINTENANCE
Open areas at bottom and around base of thermostat should be
kept clean and free from obstructions to allow proper flow of air. If
switch contacts need cleaning, this may be done with a TOOL-13
contact burnishing tool.
REPAIR
Do not field repair. If the system is not operating correctly and the
reason is traced to the thermostat, it should be replaced.
