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

where its operation will be affected
by the supply air of an adjacent unit

The unoccupied program is the night program.
Your thermostat can be set to either 2 events or 4 events per day.

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

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
RSl -
RS2 -
RS+V
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
the optional Robertshaw Remote Outdoor Sensor
(Uni-Line
#lo-529) you can select
the outdoor balance points to lock-out the auxiliary heat and/or 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 HI balance point, along with the factory
setting
of
119°F
(48°C). Any outside
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”
WIII
appear in the display meaning Lo balance point, along
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).
5. Press the RESUME button

You may also lock the cover down to prevent unauthorized access to the thermostat by adding the
clear plastic lock (included in the installation bag). To install, remove the thermostat from the
subbase and place the clear plastic lock in the subbase as shown below. Replace the thermostat
and close the cover. The cover is now 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 thermostat 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.

The first
thing
to do before programming your thermostat
IS
to determine your
own personal
comfort
levels for each day as to temperature and time. Shown above is a
typrcal
schedule.
On the weekdays, after the temperature has been lowered all night, it would be typical to have
the thermostat begin to warm the house at 6:00 AM, if you get up at 700 AM. At 9:00 AM, after
everyone has left for the day, the thermostate can be set to lower the temperature to save you
energy during the day. Before anyone arrives home in the afternoon, the temperature may again
be increased to provide comfort for you when you return. Finally, at bedtime, the thermostat
again lowers the temperature to save you energy all night.
On Saturday and Sunday when everyone is home, the temperature comes up to 68°F at 8:00
AM and stays there all day until lo:30 PM when the temperature sets back to 62°F.

(“C)
This thermostat is preset to display the temperature in Fahrenheit. You
may
change the display
to readout in Celsius. To change from one to the other, simultaneously press
theaand@
buttons. The display will change automatically.
CHANGING 12 HOUR TIME TO 24 HOUR TIME
This thermostat is preset to display the standard 12 hour time format. You may change the

release the CLOCK button, then press the MODE button. The display will change automatically.
POWER FAILURES
This Robertshaw thermostat will maintain the program settings
dunng
any type of power failure.
If power fails, “AC” will be displayed for 30 minutes. After 30 minutes, the display will go blank.
If power is restored within the first 30 minutes, the thermostat will resume normal operation.
If
power is restored after 30 minutes,
“12:OO
AM” will flash, and the thermostat will control to the
night event
setpolnt
until the clock is reset. Once the clock is reset, the thermostat will resume
normal operation.
OUTDOOR TEMPERATURE INDICATOR (OPTIONAL)
If your Robertshaw thermostat has been installed with an outdoor remote sensor, you can view
the outdoor temperature by simply pressing and holding the OUTDOOR button. The thermostat
will return to normal operation automatically.
29
To help save programming time, we suggest you use the worksheet below to set-up your
specific program.
It is suggested that you set your desired program times about 1 hour before the time that you
actually require your home to reach the set temperature. So, if you get up at 7:00 AM, set the
wake up temperature to come on at 6:00 AM.
Note: If you plan to use the Automatic Changeover Mode, you can not set your heating and
cooling temperatures closer than 2 degrees apart for the same program period.
