AG150119E 3
For THE-1105, CTE-51xx, and CTC-16xx
NOTE: These backplate kits are for THE-1105 humidity transmitters with
temperature sensors, CTE-51xx electronic thermostats, and CTC-16xx
pneumatic thermostats. The kits allow the thermostats to be mounted
to 2 x 4 inch electrical boxes or to adapt to Barber-Colman, Johnson
Controls, L&G-P, or Robertshaw/Invensys mounting plates.

Mounting for Optimal Temperature Sensing
For effective temperature sensing, mount the thermostat or sensor in a location
enabling it to sense the general room environment. The thermostat or sensor
must NOT be:
• Blocked from normal air circulation by obstructions (e.g., behind curtains or
cubicle walls).
• Exposed to artical heat sources (e.g., lights, computers, copiers, or coffee
makers) or to sunlight (at any time of the day).
• Exposed to drafts from windows, doorways, diffusers, or returns.
• Exposed to air flow through the conduit (e.g., from leaks in plenum ducts) or
other holes into the wall cavity. See Reducing Temperature Sensing Errors on
page 6.
• Mounted on an exterior wall. See Reducing Temperature Sensing Errors on
page 6.
• Mounted on or near a large thermal mass (e.g., a concrete block wall). See
Reducing Temperature Sensing Errors on page 6.
• Mounted in or near a corner. See Minimum Distance from Corners on page 3.
NOTE: The above factors primarily affect temperature sensing, but some also
affect accurate humidity and CO

sensing as well.
