Your new electronic programmable thermostat has been made even
better by the introduction of several new and improved features.
Building on its reputation for efficient and dependable operation, your
thermostat now offers the following list of enhancements.
Progressive recovery
Selecting progressive recovery on your programmable thermostat
causes the thermostat to anticipate the programmed setpoint change,
thus allowing the climate-controlled area to reach the desired setpoint
when required. The progressive recovery option is selected by pres-
sing the FAN and PROGRAM buttons simultaneously.
Thermostat and Sensor Calibration
Allows easy calibration of the thermostat and remote sensors. Simply
press and hold the FAN button for 10seconds and adjust with the up
or down buttons.
Programming Revert Time Extended
The programming revert time has been extended to 2 minutes.
Push Button Auto Repeat
Programming is easier with the push button auto repeat feature.

4.3 Power Failures During Regular Program Schedule.
Should your power fail at any time during the regular program, the
thermostat will maintain the clock internally for up to 2 hours. If the
power has not been restored during this time period, the clock will
stop. When the power is restored, the thermostat clock defaults to
a flashing 12:00 AM. The thermostat will be held in the Night
program until the user resets the clock. The thermostat will dis-
play AC when the 24 VAC is not powered. One of the unique fea-
tures of your thermostat is that there is no battery required to the
maintain your selected setpoints in the event of a power loss,
since the memory is unaffected by power failures of any duration.
There is no reason to reprogram the setpoint temperatures or start
times since the thermostat will retain these program parameters.

5 - Programming the thermostat
5.1 UNDERSTANDING 7 DAY PROGRAMMING
It is recommended that you read and understand these ins-
tructions before you attempt to program your new thermostat.
Events and temperatures (Setpoints)
Each day of the week is divided into 4 events. An event is a desi-
gnated period of time during the day. The events are called
Morning, Day, Evening and Night. Thus, Monday is divided into
Morning, Day, Evening and Night or 4 events, as is every day of
the week. Your thermostat allows you to choose between a 2
event (DAY and Night) or 4 event schedule. This is a DIP switch
selectable option. To exit programming at any time, press and
release the Resume button, or 15 seconds after pressing the last
button, the display will automatically change to the normal display.
Skipping an event (2 methods)
Your personal schedule may not require the use of all 4 events
on a particular day. For example, if you wish to go from the Day
event directly to the Night event, skipping over the Evening,
event there are 2 methods you can apply :
A) - Press and release the Program button until you come to
the day and event hour on that day that you wish to skip.
- Press and hold down the Program button and at the same
time, press and release the Mode button. In the time display
area, you
will see ”_ _ : _ _” indicating that the event is skipped.
B) - If any two or more events have the same start time, the
latest event in the day has priority and therefore uses its set-
points.
For example you may program the Morning event setpoint to
heat to 21°C. As a result, every Morning event of the week will
heat to 21°C. Next select the Day event a Heating and/or
Cooling setpoint. You will continue until you have programmed
all 4 events in the same fashion. The setpoints that you have
selected to represent your events will be consistent for all 7 days
of the week. If you change a setpoint in any of the events, it
will change the corresponding setpoint for that particular
event, for every day of the week.
Event Times
You are only required to set a starting time for each event. An
event ends et the same time that the next event begins. For
example, you may choose to have the Morning event begin at
6:00 a.m. and the Day event set to begin at 9:00 a.m.. The
Morning event ends and the temperature will automatically
change to the Day event setpoint at 9:00 a.m.
You may however vary the start times for the events for each day
of the week. For example, you may choose to have the Morning
event begin at 6:00 a.m. from Monday ti Friday but not until 8/00
a.m. on Saturday and Sunday.You may choose to program a dif-
ferent start time for each of the 4 events for each day of the
week. Remember, the setpoints for these events remain the
same day after day.
5.2 SETTING THE CURRENT DAY AND TIME
Step 1 : Press and release the CLOCK button. Display will flash
MO (Monday).
Step 2 : Press the or button until current day appears on
the display.
Note : Pressing the or buttons will remove the day back-
ward and forward.
Step 3 : Press and release the CLOCK button. Display will flash
the hour (12:).
Step 4 : Press the or button until current hour appears on
the display. Be sure AM or PM corresponds to proper time.
Note : Pressing the or buttons will move the hours back-
ward and forward.
Step 5 : Press and release the CLOCK button. Display will flash
minutes (:00).
Step 6 : Press the or button until current minutes appears
on the display.
Note : Pressing the or buttons will move the minutes back-
ward and forward.
Step 7 :Press RESUME or wait for the regular display to
appear.

This blank list is for your own use. Start by selecting your
heat/cool temperature setpoints. Determine the times you want
the temperatures to be active. Write in the desired times in the
appropriate location. Typically programming would begin on
Monday allowing you to copy the Monday schedule to the conse-
cutive days of the week.
NOTE : It is suggested that you set your desired Morning pro -
gram times about 1 hour before the time that you actually requi -
re the conditioned space to reach the set temperature. If you
wish to skip an event, refer to ”Skipping an event”.
When using the optional Outdoor temperature sensor, you can
select the outdoor balance points to inhibit the auxiliary heat
and/or compressor of your heat pump equipment.
HibP - Press and hold the outdoor button, then press the mode
button. HibP will appear on the display. Raise or lower the HibP
by pressing the or button to set the temperature above
which the auxiliary heat is locked out. If another key is pressed,
the thermostat will return to normal operation in 15 seconds.
Press the outdoor button while showing the HibP and the ther-
mostat will switch to show LobP.LobP is used to lock out the
compressor. Outdoor temperatures below the LobP will lock out
the compressor. eg. If a heat pump is set with auxiliary heat HibP
= 11°C, LobP = 2°C. When the outdoor ambient temperature is
11°C or above, the thermostat will not allow the auxiliary heat to
energize, allowing the compressor to continue to run to achieve
the setpoint. When the temperature is 2°C or lower, the thermo-
stat will automatically lock out the compressor and allow only the
auxiliary heat to energize. The factory HibP and LobP setpoints
are +48°C and -48°C.

INSTALLING an ALSRS001S INDOOR Sensor.
Introduction :
The indoor sensor is designed to sense the air temperature
at a remote location and send this information by digital
communications to the thermostat. Any number of sensors
up to six can be connected together to provide temperature
averaging. The sensor can also be modified for use with a
duct sensor.
Single Sensor Installation :
1 - Install the ARTTP thermostat according to the instruction
manual supplied with it. Check that the thermostat is opera-
ting. (Display shows the correct temperature.)
CAUTION : Remove the thermostat from the subbase while
wiring the sensor to avoid damage from live wires. This is
important.
2 - Install non-shielded 3 conductor wire from the thermo-
stat to the remote sensor location. Maximum distance is
(90m).
3 - Open the sensor case by depressing the button on the
bottom edge of the case until the latch releases. Remove
the cover by pulling it out and up at the bottom.
4 - Remove the board from the subbase by pulling back the
latch that holds it at the center bottom.
5 - Use the sensor subbase as a template to mark the
mounting hole locations on the wall. Drill size for the wall
anchors is 6 mm. Mount the subbase over the wires coming
out of the wall using the two screws and anchors provided.
The angled corner on the subbase should be in the bottom
right.
6 - Snap the board back into the subbase. Check to be sure
that the latch holds the board properly. Check that the ther-
mistor (sensor element) is positioned under the holes in the
cover but not touching the cover or subbase.
7 - Strip 6 mm of insulation from the three wires at the
Remote Sensor. Install the wires in the terminals labelled
RS2, RS+V and RS1. Push any extra wire back into the wall
cavity. Seal the hole in the wall around the cable to elimina-
te any draft that might affect the sensor. Refer to Figure 1.)
8 - Note the wire colour going to each terminal. The order of
the wires on the thermostat is not the same as the sensor.
9 - Connect the wires on the thermostat subbase to the ter-
minals labelled RS2, RS1 and RS+V. Make sure that each
terminal on the sensor is wired to the terminal with the same
name on the thermostat.
10 - Mount the thermostat on the subbase and check to be
sure that it is showing the temperature.
11 - Re-install the cover on the remote sensor by hooking it
on the top and snapping the bottom into place.
Using Multiple Sensors for Temperature Averaging :
Any number from two to six sensors may be connected
together to provide temperature averaging in a large area or
several zones being controlled by the same system.
Maximum distance between any 2 sensors is 300 ft. (90m).
1 - Wire the first sensor using the single sensor instructions.
2 - CAUTION : Make sure that there is no power to the sen-
sors by removing the thermostat from the subbase.
3 - Connect wires to each additional sensor in the following
manner. An outdoor sensor can also be connected in an
location in the chain. (Refer to Figure 2 also.)

4 - Replace the thermostat on the subbase. Check for pro-
per operation of each sensor by connecting a jumper bet-
ween terminals 1 and 2. This shorts out the thermistor. The
displayed temperature will go up several degrees if the sen-
sor is properly installed. Repeat for each sensor.
Using an ALSDS001S Duct Sensor :
The sensor and thermostat are designed to sense air tem-
perature in a room. The fast moving air in a duct has small
but rapid changes in temperature. This will affect the control
algorithm of the thermostat. For better control, it is recom-
mended that the air temperature is sensed in the room,
however, if a duct sensor is specified, installation is as fol-
lows :
1 - Install the indoor sensor using the Single Sensor ins-
tructions.
2 - Clip the thermistor from the Indoor sensor with wire cut-
ters as shown in Figure 3.
3 - Install the duct sensor in the retum air duct according to
the instructions supplied with it. Connect the two wires from
the duct sensor to terminals 1 and 2 of the indoor sensor. If
shielded cable was required because of a long distance to
the sensor box, connect the shield to terminal 2 also.
Troubleshooting :
Thermostat has no dlsplay : Check wiring between therr-
nostat and sensor. Incorrect wiring can damage the ther-
mostat, transformer or blow a fuse. Check 24VAC supply.
Thermostat reads "AC" : 24VAC power is disconnected.
Not sure if dlsplay Is showing local or remob temperature :
Breathe on the wall near the bottom left corner of the thermo-
stat. Temperature will go up for a few seconds if sensing locally.
Thermostat displays very hlgh temperature : Wires on
sensor element are shorted together. Separate them.
Thermostat displays very low temperature : Check
wiring of probe or duct sensor. Sensor element is not
connected to board or is broken.
Temperature display jumps up and down several
degrees within seconds : Thermostat requires a few
seconds to stabilize after power is turned on. If display
continues to be erratic, there is too great a distance bet-
ween the indoor sensor box and the duct sensor. Move the
box closer to the duct sensor or use shielded cable.
6 - Remote sensors
These thermostats will accept any combination up to a quantity of 6 indoor sensor(s), duct sensor(s) and outdoor
sensor(s). The sensor(s) are connected in a daisy chain to thermostat terminals RS2, RS2 and RS+V, as shown in
the relevant diagrams. The thermostat will recognize automatically, the type and number of sensors fitted.

INSTALLING an ALSOS001S (SL-ODT) Outdoor tempe-
rature sensor
Introduction :
The ALSOS001S is designed to sense outdoor air tempe-
rature and send this information by digital communications
to the thermostat. The outdoor temperature can then be dis-
played on the thermostat. In heat pump applications with
the ARTTP002S thermostat, it can also be used to control
the balance point and the auxiliary heat lockout tempera-
tures.
Installation of outdoor sensor only :
1 - Install the thermostat according to the instruction
manual. Check that the thermostat is operating. (Display
shows the correct temperature.)
2 -
Select a location for the outdoor probe that will give accu-
rate readings. Do not locate the probe where it will be influen-
ced by sunlight. The north side of the building or under the
shadow of the eaves are often good locations. Avoid loca-
tions such as near dryer vents or other sources of heat
.
3 - Mount the probe on the outside of the building using the
screw and wall anchor provided so that the tip is well away
from the surface of the wall. The cable may be routed direct-
ly through the wall or bent at the probe and routed along the
surface to enter at a more convenient place.
4 - Locate the sensor box indoor in a controlled air space
near the probe. The cable with the probe is about 1.8 mt
long. Additional 2-conductor cable may be spliced on if
necessary to increase the length.
5 - Open the sensor case by depressing the button on the
bottom edge of the case until the latch releases. Remove
the cover by pulling it out and up at the bottom.
6 - Remove the board from the subbase by pulling back the
latch that holds it at the centre bottom.
7 - Mount the subbase over the wires coming out of the wall
using the two screws and anchors provided. Drill size for the
wall anchors is 1/4 inch. The angled corner on the subbase
should be in the bottom right.
8 - Snap the board back into the subbase. Check to be sure
that the latch holds the board properly.
9 - Strip 6 mm of insulation from the two wires coming from
the probe to the sensor box. Connect the wires to terminals
1 and 2. Polarity is not important on the probe.
10 - Install three-wire cable from the thermostat to the out-
door sensor box. CAUTION : Remove the thermostat from
the subbase while wiring the sensor to prevent damage
from live wires.
11 - Strip 6 mm of insulation from the three wires coming from
the thermostat. Install the wires in the terminals labelled RS2,
RS+V and RS1. Push any extra wire back into the wall cavity.
12 - Note the wire on the thermostat going to each terminal.
13 -Connect the wires on the thermostat subbase to the ter-
minals labelled RS2, RS1 and RS+V. Make sure that each
terminal on the sensor is wired to the terminal with the same
name on the thermostat.
14 - Mount the thermostat on the subbase and check to be sure
that it is showing the temperature. It may take a few seconds to
stabilize.
15 - Press the Outdoor button on the thermostat. The out-
door temperature should be displayed with the tree and
thermometer symbol.
16 - Re-install the cover on the outdoor sensor by hooking
it on the top and snapping the bottom into place.
Using multiple sensors :
Only one outdoor sensor may be installed with a thermo-
stat. However, any number from one to six indoor sensors
may also be connected for indoor remote sensing and tem-
perature averaging.
Refer to the instructions with the indoor sensor for connec-
tiong multiple sensors. The outdoor sensor may be connec-
ted with one or more indoor sensors in the same way that
an indoor sensor is wired. The only difference in wiring is
the additional two wires from the probe which go to terminal
1 and 2.
Heat pump applications:
If the sensor is being used with an ARTTP002S thermostat
with auxiliary heat, the thermostat can be configured to
disable the use of auxiliary heat during warm weather and
to lock out the compressor when the outdoor temperature is
too cold. This can make the most efficient use of energy.
At warmer temperatures, a heat pump will operate much
more efficiently than the auxiliary heat. It can save energy
to disable auxiliary heat in some cases; for example, when
returning from setback on a mild day. The temperature
above which auxiliary heat is disabled is the auxiliary lock-
out temperature or high balance point.
Air-to-air heat pumps become less efficient as the outdoor
temperature drops. The temperature at which it becomes
more efficient to use auxiliary heat instead of the heat pump
is the balance point or low balance point.
To display the high and low balance points, while holding
down the outdoor button, press the mode button. The dis-
play will indicate the high or low balance point and the
selected temperature. Press outdoor again to toggle bet-
ween the two settings.
The factory settings allow the use of the heat pump and
auxiliary heat over the entire temperature range of the out-
door sensor.
Adjust either setting using the up and down arrow keys.
Consult a qualified installer or the heat pump manufacturers
instructions for appropriate settings.
CAUTION : Do not set the high balance point below the low
balance point as this will create a ‘dead band’ with no tem-
perature control.
Troubleshooting :
Display shows two dashes when outdoor button is pressed :
Sensor not connected properly. Check wiring between ther-
mostat and sensor. Check that sensor is not an indoor sen-
sor. Indoor sensor has a thermistor sticking out from the bot-
tom right corner of the board.)
