NOTES:
1.
Use of an adapter frame (192-308) may be
required to cover up large rough-in holes.
2.
For replacement of thermostats not listed, use
the Powers Universal Adapter Kit (192-300),
Powerstar Thermostat, and Powerstar
Thermostat. Consult you local Siemens Building
Technologies representative for details.
3.
Place the optional 1/2-inch large setpoint
adjustment knob on the shaft protruding
through the cover. Use either the hex key end
of the calibration and cover screw wrench or a
1/16-inch Allen wrench to tighten the set screw
on the knob.
4.
Install the optional guard over the thermostat
per Figure 2.
NOTES:
1.
In applications with a 1/2-inch large setpoint
adjustment knob, whenever you remove the
thermostat cover,
first
remove the adjustment
knob by loosening its set screw with either the
hex key end of the calibration and cover screw
wrench or a 1/16-inch Allen wrench.
2.
To remove the thermostat from the wall plate,
hold the thermostat firmly at the top and bottom
and start to pull the thermostat from the wall
plate. At the same time, use a screwdriver to
pry the wall plate latch arms away from the
thermostat chassis and pull the thermostat
away from the wall plate.
3.
Frequent removal and installation of the
thermostat can bend the latch arms beyond
their operating positions. If this occurs, bend the
latch arms back to their operating positions
before mounting the thermostat.
The installation is complete.
