Installing the TM-21x1
To install the TM-21x1 Series Room Temperature
Module:
1. Use the Allen-head tool to loosen the security
screw located at the top center of the housing.
2. Insert a screwdriver blade or coin into the slot on
the top of the housing.
3. Press down gently, and pry the housing away from
the base. As the two parts separate, remove the
blade or coin and continue to pull the housing away
from the base until the housing is free.
4. Pull the wires through the base. Locate the green
terminal blocks in the upper right of the base and
position the module on the wallbox with the
terminal numbers right-side up.
5. Mount the base to the wallbox using the two #6-32
mounting screws (included).
6. Wire the controller to the module. See the Wiring
section for correct wiring.
7. Attach the housing to the base and tighten the
security screw with the allen-head tool.
Mounting
Location Considerations
Mount the TM-21x1 Series Room Temperature Module
on a wall in the room to be controlled where the
occupant can easily read and adjust the setpoint dial or
fan speed override adjustment dial. Consider these
additional guidelines in determining the best mounting
location:
• Avoid areas subject to excessive vibration,
electrical noise, direct sunlight, or the effects of
radiant heat.
• Keep electrical wiring as short as possible to
minimize temperature error.
• Install modules in areas where the temperature is
representative of the general room conditions.
Wiring
To wire a controller to the TM-21x1 Series Room
Temperature Module, see the appropriate wiring
diagram (Figure 6 to Figure 10).
Note: Use 22 AWG (0.65 mm diameter) wire
minimum. Do not exceed 164 ft (50 m) between the
controller and the temperature module.
