THERMOSTAT LOCATION
To
ensure proper operation, the thermostat should be mounted on an
inside
wall in a frequently
occupied area of the building.
In addition, its position must be at least
18”
(46
cm) from any
outside
wall, and approximately S, (1.5 m) above the floor in a location with freely circulating air
Of
an average temperature.
Be sure to avoid the following locations:

doors or in corners where freely
circulating
air
IS
unavailable
l
where direct sunlight or radiant heat from appliances might affect control operation
l
on an
outsrde
wall
l
adjacent to, or in line
with,
conditioned air discharge
gnlls,
stairwells or outside doors
l
where its operation may be affected by steam or water pipes or warm air stacks in an
adjacent partition, or by an
unheated/uncooled
area behind the thermostat
l
where its operation will be affected
by the supply air of an adjacent unit
l
near sources of electrical Interference such as arcing relay contact

4. Place the rectangle opening in the subbase over the equipment control wires protruding from
the wall and, using the subbase as a template, mark the location of the two mounting holes
(exact vertical mounting is necessary only for appearance).
5. Use the supplied anchors and screws for mounting on drywall or plaster: drill two
3/16”
(5mm)
diameter holes at the marked locations; use a hammer to tap the nylon anchors in flush to the
wall surface and fasten subbase using the supplied screws. (Do not overtighten!)
6. Connect the wires from your system to the thermostat terminals as shown in the wiring diagrams.
Carefully dress the wires so that any excess is pushed back into the wall cavity or junction box,
Ensure that the wires are flush to the plastic subbase. The access hole should be sealed or
stuffed to prevent drafts from the wall affecting the thermostat.

switch to “multistage”.
LED #l (300226,306-227,3W&?9)
Switch “on” will energize the LED light pipe at the top of thermostats plus the filter indicator on the
display. This would indicate filter needs changing.
LED #2
(36&?26,3OfW27,3&%?29)
Switch “on” will energize the LED light pipe at the top of thermostats plus the wrench indicator on
the display. This would indicate service is required.
FEATURES
Remote Sensor

The thermostat is designed to accept the Remote Sensor (10528) which will allow you to locate
your thermostat in area away from view.
LED Auxiliary Heat Indicator
(3&I-226,360-227)
Your thermostat is equipped with a LED that indicates when the system has engaged auxiliary
heat mode. It is the center (RED) LED.
Add-On Heat Pumps
(30&?26,300-227)
Your thermostat is equipped to enhance the performance of an “Add-On” heat pump. The thermostat, in most
applicatons,
will perform the function of a fossil fuel kit.
To select “Add-On”, place switch
(#3
for
300-226, #5 Ibr 360-227)
to the “ON” position. The
thermostat will turn off the compressor with a call for “AUX” heat, When the switch is set to normal,
the thermostat allows the compressor and the “AUX” heat to be on simultaneously.

Plenum Fan Switch
(3~224,300-225,~229)
OFF - Fan comes on immediately with heat (used on electric heat).
ON - The fan is controlled by the system (used on gas/oil heat).
Standard/Add-on Heat Pump
(3~226,~227)
For most heat pump applications, this switch should be left In the “Standard” position. This will
allow the compressor and the auxiliary heat to be on simultaneously. For add-on heat pumps, or
heat pumps that require fossil fuel kits, move this switch to the “Add-on” position. This will turn off
the compressor with a call for auxiliary heat.

Setting the Outdoor Hi & Lo Temperature Balance Points
(300-226,300-227)
When
using

temperature above the “HibP” will lock out the
auxtliary
heat. any temperature below the “HibP”
will allow the auxiliary heat to run when called for by the thermostat.
2. Press
the@or@buttons
to set the “HibP” temperature. (A typical setting may be 52°F).
3. Press the OUTDOOR button. “LobP”

with
the factory setting of -54°F
(-48’C).
Any outside temperature below the “LobP” will lock out
the compressor, any temperature above the “LobP” will allow the compressor to run when
called for by the thermostat.
4. Press
the@or@buttons
to set the “LobP” temperature. (A typical setting may be
28°F).
