djustments
For concealed dial models (with cover removed), the
desired dial setting should be lined up with the
reference mark on the base of the thermostat.
(See Figure 12.) This will place the desired setting at
the 9 o’clock position when the thermostat is held
vertically.
Range Stops
High and low range stops can be field adjusted as
desired. Use the following procedures to set the high
and low range stops.
Note: Energy conservation models have a fixed
factory-set limited range. The stops are not
field adjustable.
