Setting The Clock – Manual Mode
In Manual mode, the real time clock simply provides a display of the current day and time. It does not control the thermostat. To
set the clock, press & hold the clock button for 5 seconds. The LCD will show the Hours Digit flashing. Use the up (p) or down
(q) button to adjust the hours to the correct time (note the AM / PM symbol) Tap the clock button and now the minutes digits
will flash. Adjust this value using the up (p) or down (q) button to show the correct minute. Tap the Clock button again and
now the weekday flashes. Again use up (p) or down (q) button to set this value to the correct day of the week. Tap the clock
button again to exit the clock set function.
Day / Night Set points (if Active)
The TZT-701 thermostat has either a single adjustable set temperature or a separate Day heating & cooling set temperature and
Night heating & cooling set temperature. If active, switching between Day & Night Modes is achieved by taping the clock
button. The Day heating and cooling set points are active when the “Sun” symbol is shown on the LCD. The Night heating and
cooling set points are active when the “Stars & Moon” symbol is shown on the LCD
To adjust the heating and cooling set points first select the day or night mode (if active) by tapping the clock button. Press and
hold the up (p) or down (q) button for a few seconds. The LCD will change and show the word “SET” and the current mode
(heating, cooling or auto) set temperature. Press the up (p) or down (q) to adjust this value to the desired temperature. If Auto
mode is selected, after the heating set point is adjusted, wait a few seconds without touching a button and the thermostat display
will change to show the cooling set point. Using the up (p) or down (q) button, adjust the set point to your desired value. After
a few seconds the thermostat display will return to normal and your new set temperatures will take effect.
Timer Mode
In some applications, the TZT-701 thermostat “Auto OFF” timer feature may be activated by the installer. When this function
has been activated the word(s) “TIMER” or “TIMER OFF” will appear in the LCD. This function is ideal when a room is not
often used and where you want to ensure the air conditioning system is not left running when the room is unoccupied.
When active, the TZT-701 thermostat will automatically turn off after a pre-programmed period of time. To provide warning of
the pending shutting down, one hour before the A/C system is about to turn off, the words “TIMER” will flash in the LCD. Once
the time period has expired the TZT-701 thermostat automatically turns off the air conditioning system. If required, pressing the
On/Off button will reset the timer and the heating or cooling will restart for the set period of time.
Should you wish you can turn the TZT-701 thermostat off at any time by pressing and holding the On/Off button for 2 seconds.
Advanced Functions
Outdoor Air Temperature Display
If the optional Outdoor Air sensor is fitted, the reading is shown in the bottom left hand corner of the LCD. If “Zoning” is also
enabled AND the Zone 2 sensor fitted, the LCD will alternate between “Outside Air” and “Zone 2” temperatures every 5 secs.
Outside Air Economy Function (If Fitted)
To further improve the energy efficiency of a suitably configured air conditioning system, the TZT-701 can use outside air for
cooling. If cooling is required and the outside air is cool enough, the outside air can be drawn in. If outside air is being used, the
word “Economy” will flash on the LCD. The air conditioner’s compressor may also run if the cooling set point is not achieved.
Note, this function cannot be used in conjunction with the Zone Control Function.
