Tap the On/Off button to turn the SMT 310 on, Press and hold the On/Off 
button for 5 seconds to turn the SMT 310 off. The LCD will Show the word 
“ON” or “OFF” to reflect the current mode. When OFF, there will be no heating 
or cooling system control regardless of the room temperature. When On the 
SMT 310 will run its pre set schedules as described below.

 When ON, the SMT 310 will control your room temperature to your desired set 
points only while displaying the word “START” in the LCD. When the word 
“STOP” is shown there the thermostat will not control the Air conditioning 
system regardless of the room temperature.

When ever you Tap the Temp “+” or Temp “-” buttons the SMT will LCD will 
flash and show the word “COOL” and the current “COOLING” Set temperature 
(the value you wish the cooling to commence at). This value can be adjusted 
with the Temp “+” and Temp “-” button. After a few seconds the SMT display 
will change and show the word “HEAT” and the current Heating Set 
temperature (the value you wish the heating to commence at). This value can 
be adjusted with the Temp “+” and Temp “-” button. After a few seconds the 
LCD will stop flashing. Your heating and cooling values are now set .

Your SMT-310 thermostat will  automatically turn the 
heating and cooling system On & Off at the times you 
require and control the room temperature to your 
previously set comfort levels. 
Programming the SMT “Start” and “Stop” times is an 
extremely simple process and requires the use of the 
“Prog” button (used to start the Programming process and 

advance through the various steps) and the Temp “+” and 

“-” buttons to adjust the necessary Start & Stop times for the 7 days.

Setting the Clock

Note:

 

Your SMT thermostat will automatically resume normal function if there 

are no buttons pressed for approximately 30 seconds. It is recommended that 

once you start to programme your SMT that you do not pause or you may 

have to commence the programming procedure from the beginning.

Step 1:

 

Press the “Prog” button once and the display will change as in Diag 

1. The word “CLOCK” will show (to indicate that we are now setting the real 
time clock to the current time and day). The hour will be flashing to indicate 
that this value can be adjusted if necessary by using the “+” & “-” buttons. Set 
the hours value to the correct time.

Step 2:

 Press the “Prog” button again and now the minutes display will flash 

indicating that if necessary the minutes value can be adjusted by using the “+” 
& “-” buttons. Set the minutes value to the correct time.

Step 3:

 Press the “Prog” button again and now the Day display will flash 

indicating that if necessary the current Day can be adjusted with the “+” & “-” 
buttons. Set the Day value.

The Real time clock was just set using just 3 buttons. The “Prog” button to 

advance us through the programming process, and the Temp “+” and Temp “-” 

buttons to adjust the value that was flashing to a new value.

Programming the SMT to automatically adjust the Start & Stop time is as 

equally a simple process. Simply press the “Prog” button to select the 

value that requires adjustment (if necessary) and then the “+” & “-” 

buttons to adjust flashing digit to the desired value.
