Congratulations!
Congratulations on purchasing TempLincTM, a small power line carrier (PLC) based
thermometer/thermostat that can be easily placed anywhere in any room with an AC
outlet. The TempLinc offers an easy way to monitor and/or control the temperature
in a room through PLC X10 communications protocol. The TempLinc can be set-up
in variety of different ways depending on the project's needs. TempLinc can be programmed as follows:
• To sendan updated temperature when a change in room's temperature is detected
• Send temperature when requested
• Act as a thermostat
• Operate in a combination mode that combines the thermostat mode with either a
report on change or repor t on request
All of this can be done in either Fahrenheit or Celsius temperature scales depending
on the project's requirements.
TempLinc is designed to be a general-purpose temperature sensor for home
automation use. It should not be relied upon for to prevent damage that may occur
if temperatures drop too low or rises too high. Because of the nature of PLC communications, there is a possibility that signals sent by TempLinc may not be
received. The electrical components in TempLinc and its PowerLinc II™ powerline
communications interface module may fail or lockup upon exposure to temperature
extremes, even those that the TempLinc manual specifies that TempLinc can sense.
Additionally, like all home automation products, TempLinc should never be used for
life saving or life-preserving situations. TempLinc is not a replacement for smoke or
fire detectors and should not be relied upon as the only means of protecting a home
from freezing temperatures.
Key Features
• Reports temperatures between -60°F and 131°F
• Reports temperature in Fahrenheit or Celsius
• Programmable to transmit upon temperature changes
• Programmable set point reporting
• Uses RCS-compatible temperature chart
• Small sized sensor
• Includes new PowerLinc II Interface module with pass-through AC outlet
• Compatible with Smarthome Live and Smarthome Action
Compatibility with Third Party Home Automation Programs
TempLinc uses the same translation table as the RCS family of powerline controllable thermostats. Many home automation programs already support these thermostats. When setting up the TempLinc for use with a home automation program, look
for support of RCS model TX15-B (it might also be described at "Bi-Directional" or "2Way").

Parts included with TempLinc
• The TempLinc sensor
• PowerLinc II PowerLine Interface Module
• PowerLinc II connecting cable
• Double-sided foam tape and mounting screws
Please note that this PowerLinc II interface is
designed to only work with the TempLinc sensor.
While it resembles our regular # 1132B PowerLinc
II interface, the two are incompatible and not interchangeable. The included
PowerLinc Interface contains dif ferent circuitry and programming to support only the
TempLinc sensor. The AC outlet on the front of the PowerLinc II interface is a passthrough outlet for any 120-volt electrical device. It does not have any automation
functions.
Installation
Locate the TempLinc in an area that has good air flow and is located near an electrical power outlet. The TempLinc can be mounted either vertically or horizontally, for
best results it is recommended that a vertical position be used. TempLinc is not
weatherproof and should not be used outdoors or for measuring water temperature.
Doing so may shorten the life of the sensor module.
1. The TempLinc comes with double-sided tape to secure it to the surface. Once
the location is chosen, make sure the mounting surface is clean and free from
dust, dirt, and debris.
2. Remove the protective sheet from one side of the double-sided tape to expose
the adhesive portion and apply it to the back of the TempLinc
3. Remove the protective sheet from the other side of the double-sided tape to
expose the other adhesive portion and place it over the mounting surface and
press firmly to secure it.
4. With the TempLinc secured in placed, connect the cable between the
PowerLinc and the jack of the TempLinc.
Do not plug the PowerLinc in until instructed to do so in the programming section of
this manual.
Because of the way TempLinc communicates over the AC wires, it may be difficult to
have other modules on the same house code used by TempLinc. You may want to
study the signals sent between the TempLinc and your home automation control
program(s) to find addresses for other modules. Or, simply set-aside the entire
house code for TempLinc's exclusive use.
Quick Start Instructions
1. Un-plug the PowerLinc II from the AC outlet for 10 seconds
2. Plug in the PowerLinc II into the outlet and wait three seconds
3. Within one minute of plugging in the PowerLinc II, send the following:
i. Send the base house/unit code of the TempLinc three times in a row
ii. Send the house/unit code for the Operation Mode
(see Table 1 on page 7 for operating modes)
iii For Thermostat modes, send the set point using unit codes
(See page 7 for more detailed instructions)

New Features in TempLincs with the PowerLinc II interface
With the changeover to the new PowerLinc II interface, we have taken some time to
implement some user-suggested improvements. Since most of the brains of the
TempLinc system are in the PowerLinc II interface, any TempLinc sensor and cable
will have these improvements when used with the PowerLinc II interface.
(Remember, the TempLinc must be used with a specially made and programmed
PowerLinc II interface.)
Status Request signals can be sent in any mode
Status Request commands are now accepted and responded to in any mode the
TempLinc is programmed into. Previously, TempLinc would only respond to Status
Request commands if it was programmed in the "Report on Request" mode.
PLC signals are now sent twice
To improve signal reliability, the TempLinc will send ON and OFF commands twice
(when set to one of the thermostat modes). Additionally, the TempLinc will hold off
transmitting if it detects signals on the powerline from other PLC transmitters. (This
is sometimes called Polite Mode or Signal Collision Avoidance.) By sending the signal twice, the odds are increased that a complete transmission of data will arrive at
the receiver(s).
Transmissions after a power failure
When the TempLinc is powered up (for the first time or after a power failure),
TempLinc will check the temperature and if it is beyond the programmed set point
(in the thermostat mode), it will send a PLC signal to activate the controlled device.
Send on Change mode now ignores small temperature changes
This was an improvement suggested by many of our users. TempLinc will no longer
send PLC signals if a small change in temperature is detected. Previously, when
TempLinc was in the Send on Change mode, it would send a PLC signal every time a
temperature change was detected. In some cases, this could cause a flood of PLC
signals and unnecessary cycling of equipment controlled due to TempLinc's temperature reporting. With this improvement, the TempLinc will not send a PLC signal if
the temperature changes back to the previous temperature.
See Chart below

Page 5
Temperature sensing for Report on Change Modes changed
The TempLinc will now check for temperature changes every minute rather than
every eight milli-seconds. This change was requested because in some cases, the
TempLinc was detecting changes as a result of minor temperature disturbances.
For example, someone walks by the sensor or there is a sudden gust of airflow
across the sensor, the old TempLinc would have sent a flurry of PLC signals in
response to every change. When in the Thermostat Mode, it will still send an ON or
OFF the instant it senses a temperature change.
Programming and controlling the TempLinc
Using a Max-controller
The TempLinc will need to be programmed with a Maxi-Controller
(Smarthome #4020) or an equivalent transmitter capable of sending Housecode and Unit Codes without ON or OFF commands. The
buttons are separated into Addresses and Command functions,
which allow it to send individual commands. Transmitters in which
one button is pressed to turn a load on or off WILL NOT WORK.
When using a Maxi-Controller or an equivalent transmitter, be careful when pressing the buttons. Commands will be ignored if some
commands are not sent in the right sequence. "Fat-Fingering" or accidentally pressing the same button twice may prevent the programming from being accepted. This
same transmitter is also used for setting scenes, addresses, and other advanced
features in Smarthome plug-in modules, light switches, and KeypadLinc wall-mounted transmitters.

Windows-based TempLinc Program
Smarthome has created a small Windows-based PC program to help program and monitor TempLinc. It is available as a free download from the TempLinc product
page on Smarthome.com:
http://www.smarthome.com/1625.html
It requires the use of a Serial PowerLinc interface.
The program gives you access to all the features of the
TempLinc. It also includes step-by-step commands to
aid in the programming of the TempLinc.
Third-party programs
As of this manual's publication, we have found that the programs below offer some
support and control for the TempLinc.
• Home Control Assistant (version 4.15 and above)
• HomeSeer Home Automation Software
• Indigo Software for Mac (version 1.3.0 and above)
• Zeus Home Control (version 3.1 and above)
Please note: there are no guarantees that these programs operate flawlessly or that they will continue to
include support for TempLinc. Smarthome make no guarantees or endorsements of these products.

Modes of Operations
The TempLinc can be setup in a variety of different ways depending on the project's
needs. To make programming more of a simple task, decide ahead of time which
mode of operation the TempLinc is to work in. There are eight operation modes that
can be chosen among: Additionally, these modes can measure or report in the
Fahrenheit or Celsius temperature scales.
Report on Change
TempLinc will report the new room temperature whenever a change is detected.
TempLinc will send a house/unit code and preset dim (B15 - Predim6) that corresponds to the current temperature. Refer to Table 2 for a list of temperatures and
their corresponding codes. It will also respond to Status Requests commands
Report on Request
TempLinc will report the room temperature whenever a status request signal is
received. Sending the house/unit code plus the house code/status request (B1 - B
Status Request) to TempLinc will return house/unit code and preset dim of the current temperature. Refer to Table 2 for a list of temperatures and their corresponding
codes).
Thermostat (Cooling)
TempLinc will act like a thermostat in cooling mode. Set the temperature set point
by sending a house/unit code combination described in the programming section.
Once the temperature set point is programmed, TempLinc will send out its
house/unit code and house code + "ON" (B1 - BON) if the temperature is higher
than the set point or house code + "OFF" (B1 - BOFF) if the temperature is lower
than the set point.
Cooling Combination 1
This combination combines the report on change feature along with the thermostat
cooling mode feature.
Cooling Combination 2
This combination combines the report on request feature along with the thermostat
cooling mode feature.
Thermostat (Heating)
TempLinc will act like a thermostat in heating mode. Set the temperature set point
by sending a house/unit code combination described in the programming section.
Once the temperature set point is programmed, TempLinc will send out its
house/unit code and house code + "ON" (B1 - BON) if the temperature is lower than
the set point or house code + "OFF" (B1 - BOFF) if the temperature is higher than
the set point.
Heating Combination 1
This combination combines the report of change feature along with the thermostat
heating mode feature.
Heating Combination 2
This combination combines the report of request feature along with the thermostat
heating mode feature.

Programming
With the mode of operation determined, the TempLinc can now be programmed.
Programming will require a PLC transmitter that can send separate unit and function
codes. A Maxi-transmitter, Smarthome #4020 or X10 #SC503 or PHC02 is ideal for
programming the TempLinc. All programmed settings are stored in an EEPROM and
will not be lost if the power is removed or disrupted.
1. Put TempLinc into programming mode by plugging the PowerLinc interface
module into a 120-volt wall receptacle.
2. Within one minute after plugging the PowerLinc into the wall, send the base
house/unit code of the TempLinc three times in a row (D5, D5, D5).
3. Set the operating mode from the table below by sending the house and unit
code (the house code is the same as the one used for the base address)

House code + "1" Repor t on change Fahrenheit D1
House code + "2" Repor t on request Fahrenheit D2

Programming(continued)
Setting the Set Point in the Thermostat Mode
An additional step is needed for thermostat mode, programming the temperature
set point. After sending the mode command, send a house/unit code combination
that corresponds to the temperature set point at which the TempLinc sends ON or
OFF signals. The first unit code sent is the first digit of the set point temperature
and the second unit code is the second digit. Unit codes 1 through 9 represent digits 1 through 9, for 0 use unit code 10. The set point temperature is limited to a
positive two-digit number between 00 and 99. If the project requires the use of set
points above 99 degrees Fahrenheit, use the TempLinc in the Celsius mode.
Example:
To put the TempLinc in thermostat cooling mode with a set point of 78° in the
Fahrenheit scale and the base address to be L15, send L15, L15, L15, L3, L7, and
L8. The unit codes 7 and 8 will set the temperature to 78°F.
The hysteresis in thermostat mode is 2°F (1°C). In cooling mode, the thermostat
will shut off about 2° lower than the set point. In heating mode, the thermostat will
shut off about 2° higher than the set point.
Any time the TempLinc needs to be reprogrammed or updated, unplug PowerLinc
and leave it unplugged for about 10 seconds. Afterwards, plug the PowerLinc back
in and follow the programming procedure from the beginning.
TempLinc Temperature Reporting
When the TempLinc is in the Report on Change or Report on Request modes, it will
transmit a house/unit code and preset dim level to represent the temperature.
Table 2 shows the temperatures that correspond to each house/unit code and preset dim. The Temperature to PLC Code Translation Table is directly supported by
many home automation systems.
Decoding the Current Temperature Sensed by TempLinc
1. Look at the house and unit code that the TempLinc transmitted. The house
code will match the base house code of the TempLinc and the unit code will
either be 11,12, 13, 14, 15, or 16
2. Select the column that matches the house/unit code sent by the TempLinc
3. Look at the preset dim that was transmitted by TempLinc and match it to the
preset dim value in the left column
4. Once matched, follow that row to the right until house/unit code column is
matched
5. The number that is in the box where the row and column meet is the temperature

Using TempLinc in areas with extreme temperatures
The TempLinc sensor head can reliable measure temperatures from -60°F and
131°F. However, the PowerLinc Interface, which contains the processing electronics
of the TempLinc system is only rated to work between 32°F and 120°F. If the
PowerLinc Interface is exposed to temperature beyond its rated limit, the whole system may lock-up, or report erratic data. Keep the PowerLinc Interface in an area
where the temperatures are between 32°F and 120°F for reliable operation. The
data cable between the sensor head and the PowerLinc Interface can be reliably
extended with Smarthome #1132E 12 ft. PowerLinc Extension Cable.
