Congratulations on the purchase of your new
Your new Smart Temp SMT thermostat has been built using the best
components and design philosophy. As a consequence of this, if properly
installed your new electronic programable thermostat will provide you with
many years of trouble free and reliable service.
The Smart Temp SMT has been designed to be attractive, highly reliably and
simple to use. Please take the time to read these simple instruction to
familiarise yourself with the function and features offered in this product.

To turn the System On

With each press of the "ON" button, the SMT will toggle between "On" and "Off" mode. The SMT retains in memory the last temperature set point
and operational mode. These values are used when the SMT is turned on.

To Adjust the Set (or desired) Room Temperature

When no buttons are pressed, the LCD indicates the current room temperature. When the up (+) or down (-) buttons is first pressed the LCD will
flash rapidly and indicate the Set (or desired) room temperature. The word "SET" will also be displayed in the LCD to confirm the set temperature is
being adjusted.
When the desired set temperature is shown and there are no further button presses the LCD will stop flashing and again indicate the current room
temperature. The new desired room temperature is now active and the SMT will control the Air Conditioning system to archive this new desired
temperature.

To select the System Modes

Pressing the "Mode" button will permit you to select the operational mode of the thermostat. Each press of the mode button cycles between Heat
only mode, Cool only mode, Auto mode (Indicated by the words Heat & Cool in the LCD) or fan only modes.
Heat Mode: In heat mode, the thermostat will only activate the system heating when the room temperature falls below the set (or desired)
room temperature. Heat will be displayed in the LCD to indicate this mode is set. When the SMT is calling for the system to heat, the word
"HEAT" will flash slowly in the LCD. In this mode, the SMT will not turn on the Air Conditioning equipment to cool the room.
Cool Mode: In cool mode the thermostat will only activate the system cooling when the room temperature raises above the set (or
desired) temperature. Cool will be displayed in the LCD. When the SMT is calling for the system to cool, the word "COOL" will flash slowly
in the LCD. In this mode, the SMT will not turn on the Air Conditioning equipment to heat the room.
Auto Season Change over Mode: In Auto mode the thermostat will automatically activate the system heating or cooling to maintain the
set (or desired) temperature to within +/- 0.8 Deg C (approx). For example, if the set temperature is 21 deg C, the SMT will activate the
system cooling when the room temperature raises to 22 deg C and activate the system heating if the room temperature falls to 20 deg C.
The LCD will indicate Auto Season Mode by displaying both "Heat & Cool" in the LCD. When the SMT is calling for the system to heat or
cool the appropriate word will flash slowly in the LCD.
Fan only Mode: In fan only mode the SMT will only run the system fan regardless of the set and room temperature. The SMT will not
attempt to control the Air Conditioning System heating or cooling functions.
Fan only mode is typically used to improve building ventilation and not to control room temperature.

Emergency Heat Mode ( EH )

Selecting this mode disables the use of compressors in heating when in Heat Pump mode. Heating is controlled only via W2 (AUX Heat ) terminal .
To select this mode Press and Hold the Fan button for 5 Second, the Display will show "H"using the Up or Down button you can toggle between "H"
or "EH" modes. ( Default is" H" normal heating operation with use of compressors, Y1 & Y2 )
To select the Fan Mode (Accessed with the "Fan" Button).
Continuous Fan Mode
In Continuous Fan mode the system fan will run 24 hours per day, but unlike the Fan Only mode described above the SMT will also
control the room temperature as dictated by the Heating, Cooling or Auto modes set above. The SMT will indicate that this mode is active
by displaying the word "Fan" in the lowest section of the LCD.
Auto Fan Mode
In Auto Fan mode the SMT will only turn on the system fan on when there is a call for system heating or cooling and off again when the
room is at the desired temperature. The LCD will indicate that this mode is active by displaying the words "Auto Fan" in the lowest
section of the LCD.
