Smart Temp SMT-80 & SMT-80RF User Manual
Thank you for your purchase of the
SMT-80 digital thermostat or the SMT-
80RF wireless thermostat by Smart
Temp Australia P/L. Please take the
time to read and understand these
simple instructions so that you may
benefit from the advanced features and
functions integrated into this quality
product.
The SMT-80 is available in 2 versions. In
terms of the user experience the two
versions are almost identical. The only difference being the SMT-
80RF communicates to the heating and cooling system by radio
frequency rather than being hardwired to it. This feature permits
you to take the thermostat into any room with you* to ensure better
temperature control where you are
The Smart Temp SMT-80 is a digital, non-programmable thermostat
that has many energy saving functions. It will control your heating
and/or cooling system precisely and in an energy efficient manner.
Operating the Heating and Cooling System
A backlit display shows current room temperature as well as other
important information. Four buttons are provided to permit the
control of the SMT-80 functions.
Up Button
Use this button to increase the set temperature.
Down Button
Use this button to decrease the set temperature.
Mode Button
Each tap of the Mode button will cycle the SMT-80
through all available modes. (Heat, Cool and Off)
Note - Not all modes may be active on your SMT-80.
Off –The Heating and Cooling System is OFF
“OFF” is displayed in the LCD when the SMT-80 is OFF
“OFF”will flash in the LCD if the SMT-80 has been remotely turned
off by the Auto Off or a remote input. In this case you may not be
able to turn the SMT-80 on using the Mode button.
Heat Mode –Only the Heating System Will Operate
“Heat ON”will be shown when the heating is running. “Heat”will
flash if the heat delay timer is running, please wait up to 5 minutes.
Cool Mode –Only the Cooling System Will Operate
“Cool ON”will be shown when the cooling is running. “Cool”will
flash if the cool delay timer is running, please wait up to 5 minutes.
Auto Mode - Both the Heating and Cooling Systems Will Operate
Auto mode will Heat when the room is cold or cool when the room
is warm automatically.
Light/Fan Button
Selects Auto Fan or Continuous Fan and/or brings
on the display backlight.
“Fan” will be shown whenever the fan is running or “Fan On” will be
shown whenever the fan button was used to switch the fan on
manually.
Adjusting Your Set Temperature
Make sure Heat, Cool or Auto mode
is selected. Press the [Up] or [Down]
button and the display will change
and show “SET”, and “Heat Set”or
“Cool Set” with the current set
temperature in the main part of the
display. Continue to press the [Up]
or [Down] button until your desired set temperature is shown.
If Auto mode is selected, you are first given the opportunity to adjust
the cool and then the heat set temperature separately.
Note - Your range of adjustment may be limited by the installer.
“Set Limit Reached” is shown when this is the case.
Low Battery Warning
Your SMT-80 controller may be poweredby 2 x AA Alkaline batteries.
When these batteries run low a battery symbol will be shown on the
display and the backlight will be disabled. Normal heating and
cooling will still function. If you ignore this first warning
eventually the heating and cooling will shut down and
the display will show only the flashing low battery
symbol and the text “Low Batt”.
Replace with AA ALKALINE batteries only.
SMT-80 RF Signal Icon
The “RF” signal indicator will remain steady when
communication is established and will flash when
the signal is absent. If communication is lost for
extended an time, the SMT-80 will stop all heating and
cooling.
* The SMT-80 RF has a maximum range of 30M inside depending on
wall construction and other factors that may limit range.
Motorised Zone Damper Control Function (Optional)
Your SMT-80 & SMT-80RF can be set up by your installer to either
control a conventional heating and/or cooling system OR to control
a motorised zone damper.
In Zone damper control mode your SMT-80 or SMT-80RF compares
the current zone temperature with your set temperature and the
temperature of the air produced by your heating or cooling system
(that is controlled by its own thermostat). If the air produced by your
heating and cooling system will bring your zone to your desired
temperature it will open a motorised damper and allow conditioned
air into the zone. If the air produced by your heating and cooling
system is not suitable to bring your zone to your desired
temperature it will close the motorised damper and block the flow
of air into your room.
Note - In Zone Damper Control Mode the SMT-80 or SMT-80RF is
NOT controlling the main heating or cooling system.
Hint –If your installer has set your SMT-80 or SMT-80RF to Motorised
Zone Damper Control mode the decimal place in the room
temperature display will blink.

SMT-80RF Wiring Examples
The SMT-80RF is a 2-part controller that consists of a battery
powered controller and a 24VAC powered receiver. The two
parts communicate with each other via radio frequency
(433MHz).
The battery powered controller measures the temperature of
the room that it is in and transmits data to the receiver
module fitted in the heating and cooling system. This permits
you to move the battery powered controller from room to
room should you wish.
Note 1 –If moving the battery powered controller do not place
it on any warm or cool surfaces as this will affect the comfort
of the room.
Note 2 –The maximum distance the battery controller can be
from the receiver is typically 30M indoors.
Pairing the Controller and Receiver
Your Controller and Receiver should be “pre-paired” when
you receive them. If for any reason you need to re-pair the
units, the steps are detailed below. This may be necessary
when you have multiple SMT-80RF in close proximity to each
other to permit you to select different transmission channels
for each paired unit (as indicated in step 4 below).
1Ensure you have 2 “AA” alkaline batteries fitted to
the SMT-80 Controller and it is powered on.
2Ensure the SMT-80 Receiver module is powered on
being hardwired with 24VAC. (The amber data link
will blink a heartbeat).
3Press and hold both the [Up] and [Light /Fan] buttons
on the SMT-80RF Controller until the display changes
and shows the currently selected channel number.
4If you wish –adjust the channel with the [Up] or
[Down] button. (If you have multiple units in your
home or office they should all have a different
channel number)
5Press and hold the [Pair] button on the Receiver until
the green pair light blinks.
6Press the [Fan] button on the SMT-80 Controller to
initiate the pairing process.
The SMT-80 Controller will show the RF signal confirmed icon
on the display and the green paired LED will remain
ON solid when the units are paired.
When data is being passed between the Controller and the
Receiver the amber “data” LED will flash.
Receiver Module Wiring
The SMT-80RF
Receiver module
should be mounted
in a clean, dry
location and within
30M of the
proposed Controller
location. (Note - the
range varies based
on environment)
Avoid placing the Receiver module inside an earthed metal
case such as a gas heater enclosure as this will significantly
reduce the RF signal range.
SMT-80RF Troubleshooting
No LEDS on Receiver module
Check 24VAC power supply is in the CR terminal
Poor Range
Check Receiver location
Ensure Receiver not mounted inside metal enclosure
Check SMT-80 batteries
Check for other strong RF signals that maybe close
Pairing Process Fails
Remove batteries and power down receiver for 5
minutes and try again
Green LED Off / RF Signal Icon Blinking
See Poor Range (Above)
Try “Re-Pairing” the SMT-80 with Receiver module
Amber LED Rapidly Blinking
This is normal - data is being transmitted / received
