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 out-
side wall, and approximately 5', (1.5 m} above the floor in a location with freely circulating air of
an average temperature.
Be sure to avoid the following locations:
• behind doors or in corners where freely circulating air is unavailable
• where direct sunlight or radiant heat from appliances might affect control operation
• on an outside wall
• adjacent to, or in line with, conditioned air discharge grilles, stairwells or outside doors
• where its operation may be affected by steam or water pipes or warm air stacks in an adja-
cent partition, or by an unheateci/uncooled area behind the thermostat
• where its operation will be affected by the supply air of an adjacent unit
• near sources of electrical interference such as arcing relay contact

REMOVING THE THERMOSTAT FROM THE SUBBASE
1. Insert a flat blade screwdriver or coin 1/8"
into the slot located in the bottom center of
the thermostat case and twist 1/4 turn.
When you feel or hear a click, grasp the
case from the bottom two corners and sep-
arate from the sibbase as shown in the dia-
gram at the left. Some models require more
force than others when separating due to
the number of terminals used.
2.
Swing the thermostat out from the bottom.
3. Lift the thermostat up and off the subbase.
4. Place the ectangular opening in the sibbase 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 over tighten])
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 wail 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 affecting the thermostat.

DESCRIPTION OF THE DIP SWITCH FUNCTIONS
2 Events or 4 Events Per Day pm -225, 300-227. 300-229)
Your thermostat can be set to either 2 events or 4 events per day.
2 events will allow you to program a Day
h
, setting and a Night ( setting.
4 events will allow you to program Morning ñ Day 0, , Evening and Night ( settings.
Smart Fan (300-225, 300-227, 300-229)
When the Smart Fan switch is in the ON position and the fan has been energized (during
the occupied program), the thermostat will keep the fan running continuously during the occu-
pied programs and automatically cycle the fan with a call for heating or cooling during the unoc-
cupied program. NOTE The unoccupied program is the Night program.
2 Minute or 4 Minute Minimum On Times
Keypad Lock
Place the switch in the locked position to lockout all buttons except the OUTDOOR button.
Plenum Fan Switch (300-224, 300-225, 300-229)
OFF - Fan comes on immediately with heat (used on electric heat).
ON - Fan is controlled by the system (used on gas/ail heat).
Standard/Add-on Heat Pump
(300-226,300-227)
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.

Single or Multistate (300-227, 300-229)
For eguipmtht with a single compressor 12 heat/1 cool for 300-227 or 1 heatil cool for 300-
229}, switch to single stage. For equipment with two compressors (3 heat/2 cool for 330-227 or
2 heat/2 cool for 300-229), switch to multistage.
LED #1 (300-226, 300-227, 300-229)
Switch ON will energize the LED light pipe at the top of the thermostat plus the filter indicator on
the display. This indicates the filter needs to be changed.
LED #2 (300-226, 300-227, 300-229)
Switch ON will energize the LED light pipe at the top of the thermostat plus the wrench indicator
on the display. This indicates service is required.
FEATURES
Remote Sensor RS1 — R52 - RS+V
The thermostat is designed to accept the remote sensor (10-528) which will allow you to locate
your thermostat in an area away from view.
LED Auxiliary Heat Indicator (300-226, 300-227)
Your thermostat is equipped with an LED that indicates when the system has engaged auxiliary
heat mode. It is the center (red) LED.
Add-On Heat Pumps (300-226, 300-227)
Your thermostat is equipped to enhance the performance of an add-on heat pump.
In most applications, the thermostat will perform the function of a fossil fuel kit.
To select Add-On, place switch (#3 for 300-226, #5 for 300-227) to the ON position. The ther-
mostat 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.

Setting the Outdoor High and Low Temperature °Mance Points (300-226, 300-227)
When using the optional Robertshaw remote outdoor sensor (Uni-Line If 10-529), you can select
the
outdoor balance points to loch-out the auxiliary heat andlor the compressor of the heat
pump.
To set the balance points:
1. Press and hold the OUTDOOR button, then press the MODE button. HibP will appear in the
display meaning high balance point, along with the factory setting of 119"-F (48T). Any out-
side temperature above the HibP will lock out the auxiliary heat, any temperature below the
HibP
will allow the auxiliary heat to run when called for by the thermostat.
2. Press the s or t buttons to set the HibP temperature. (A typical setting may be 52`F)
3. Press the OUTDOOR button. LobP will appear in the display meaning low balance point,
along with the factory setting of -54'F (-48T). Any outside temperature below the LobP will
lack out the compressor, any temperature above the LobP will allow the compressor to run
when called for by the thermostat.
4. Press the a or t buttons to set the LobP temperature. (A typical setting may be 28'F.)
5. Press the RESUME button.

COVER LOCK
You also may lock the cover down to prevent unauthorized access to the thermostat by adding
the dear plastic lock (included in the installation bag). To install, remove the thermostat from the
subbase and place the dear plastic lock in the subbase as shown below. Replace the
thermo
stat and close the cover. The cover now is locked. To open, simply use a screwdriver to push
the lock back allowing the cover to open. To remove the lock, open the cover, remove the ther-
mostat from the subbase, then remove the lock.
REPLACING THE THERMOSTAT ON THE SUBBASE
1.
Position the thermostat on the hinged tabs located at the top of the subbase.
2. Gently swing the thermostat down and press on the bottom center edge until it snaps in place.
