Installation Location
The instrument should be installed in indoor locations meeting the following
conditions:
• Instrumented panel

to wind may cause the temperature sensor accuracy to deteriorate. To mount mul-
tipleindicating controllers, see theexternaldimensions/panelcutout dimensions
which follow.
