- Procedure
- 1. Attach the mounting plate to the switch box with the two flathead screws provided. Be sure the mounting plate is vertical.
- 1. Remove the screws holding the protector black in place. Pry out and discard the protector block. Pull out and discard the short piece of plastic tubing inserted in the connector head.
- 2. Attach the thermostat mounting plate to the connector head with the two flathead screws provided. Be sure the mounting plate is vertical.
- 3. Measure 7/8-inch from the back of the thermostat and cut the tubing at a 45° angle to make the tubing slide into the connector head easily. Remove the coil spring from the tubing and discard.
- 4. Insert two 3/4-inch lengths of copper tubing, supplied with the thermostat into the plastic tubing to stiffen the plastic tubing so it can be installed easily.
- 5. Place the fiber board insulator over the tubes on the back of the thermostat.
- 6. lubricate the outside of the two plastic tubes (this applies to the mortar joint fitting only) with water or glycerin. Be sure that none of the lubricant gets inside the tubing.
- 7. Insert the tubes in to the connector head. Slightly rotate the tubes back and forth, and push firmly into the sockets at least 1/4 inch.
- 8. Fasten the thermostat to the mounting plate with Allen screws provided, and tighten evenly.
- CHECKOUT
- RUN/ADJUST
- 1. Measure temperature at sensing element. This should be stable temperature.
- 2. Rotate setpoint dial to this temperature.
- 3. With 15 psig (103.4 kPa) supplied to thermostat, adjust calibration screw until 3 psig (20.7 kPa) is read on branch test gauge.
- 4. Rotate the setpoint dial in a direction which raises the output until 13 psig (89.6 kPa) is read on the branch gauge.
- 5. The difference between the setpoint dial readings in Step 2 and 4 is the throttling range of the thermostat.
- 6. If the throttling range in Step 5 is not that desired, move the throttling range slider (Figure-4) in the appropriate direction and repeat Steps 2 through 5 until the desired throttling range is obtained.

- 1. Remove the thermostat cover by loosening the cover screw.
- 2. Using a 5/64-inch Allen wrench, unscrew (counterclockwise rotation) the test point screw one full turn (Figure-4).
- 3. Attach the test gauge rubber seal to the boss, as shown. Using a rotary motion, push the gauge on as far as it will go (1/4-i...
- 4. Adjust the setpoint dial to the room temperature as indicated on the test thermometer.
- 5. With a 0.48-inch six spline wrench, turn the calibration screw (Figure-6) clockwise if the controlled pressure is above 8 psi...

- 1. Insert the blade of the tool or screwdriver between the switchover plunger and the switchover lever shown in Figure-5. The top bimetal should be approximately 1/32-inch off the lever and the bottom bimetal should be in contact with the lever.
- 2. With a .048-inch six spline wrench, turn the calibration screw clockwise if the controlled pressure is above 8 psig (55.1 kPa...
- 3. Manually switch the thermostat several times by removing and reinserting the AL-80 or screwdriver and observing the branch line pressure. If it varies beyond the limits, repeat the calibration.
- 4. Remove the test gauge.
- 5. Turn the test point screw clockwise to tighten.
- 6. Replace cover.
- 1. Measure temperature at sensing element. This should be stable temperature.

DEVICE INFORMATION
Identification
Thermostats of this family may be easily identified by
referring to the part number located on the carton and
on the back and side of the device.
These thermostats are used for proportional control of
pneumatically activated valves, dampers and similar
devices in heating, ventilating and air conditioning
systems. See
Table-1.
Pre-Installation
The thermostats are shipped with mounting screws and
three 3/4-inch long copper tubes. Wall fittings must be
ordered separately.
Air connections: Two plastic tubes reinforced with a
coil spring are coded M & B. The M (Black) designates
the supply main and the B (White) designates the
controlled branch line.
Model TK-1601 has three plastic tubes. The additional
tube A (White) designates the auxiliary (two-position)
branch line.
INSTALLATION
Requirements
Locate the thermostat where it will be exposed to
unrestricted circulation of air which represents the
average temperature of the controlled space. Do not
locate the thermostat near sources of heat or cold,
such as lamps, motors, sunlight, or concealed ducts.
Maximum safe ambient temperature is 150
°F (65 °C).
Note: No fitting is available for use for flush mounting in
masonry walls when using the TK-1601, an electrical box is
used for this application (Figure-1).
