TM-21x1 Series Room Temperature Module Installation Instructions
1
Applications
The TM-21x1 Series of Room Temperature Modules
are designed for use with the Facility Explorer Series of
field controllers. The setpoint dial enables the room
occupant to adjust the working setpoint of the
controller. On scaled models, the marked adjustment
range is 55 to 85°F; the controller determines the
actual setpoint temperature. On Warmer/Cooler
models, the adjustment range is /- from
midpoint of the dial; the controller determines the
equivalent setpoint temperature.
With the occupancy button, the occupant can switch
the controller’s operating mode between occupied and
standby. In addition, the TM-21x1 Series offers the
option of a temporary occupied mode during
unoccupied mode.
The TM-21x1 Series Room Temperature Module also
features a Light-Emitting Diode (LED) that indicates the
current operating mode.
