Manual Mode Indicator.
These words (or the lack of any programming information such as “Start”& “Stop”, or “Wake” “Leave” “Return” & “Sleep”)
indicate the TZT-701 thermostat is in “Manual Mode”. This mode is perfect for those who have a less structured lifestyle. Your
TZT-701 thermostat may be set to provide two separate set points, offering a Day temperature and a separate Night temperature
to be set, and easily swapped between the two as needed. Alternatively, a single heating and cooling set point may be provided.
In this case the day & night symbols will not be shown. This function is described in more detail on page 12 of this manual.
Clock.
The clock displays the time. This time is used by the TZT-701 thermostat in Programmable mode (2 or 4 events) to set the
start/stop or program events so it is important that the clock is set correctly. The Clock is NOT used by the TZT-701 thermostat
in manual mode – it simply displays the time. See programming on pages 8 & 10 for details about setting the clock.
Day Indicator.
As with the clock described above, the TZT-701 thermostat relies on having the correct day set for its programming functions to
be accurate. See programming on pages 8 & 10 for details about setting the clock and day display.
Room / Set Temperature.
This portion of the LCD displays the current room temperature. (Note this temperature may or may not be measured at the
location of the TZT-701 wall controller). In programming mode the current SET (or desired) room temperature is displayed in
this location. The temperature is display in either degree Celsius or degrees Fahrenheit as set by the installer.
Outdoor / Zone Temperature.
This part of the display requires optional sensors to be installed to enable this function. Both the second control zone temperature
and or outdoor temperature can be displayed.
System Mode Indicator.
This part of the LCD provides information on the Air Conditioning System control mode. The TZT-701 thermostat is capable of
controlling heating only, cooling only or both heating and cooling systems together. If heating only mode is selected the word
“Heat” is displayed. If cooling only mode is selected the word “Cool” is displayed. Auto season changeover mode is indicated by
the words “ Heat & Cool” both being displayed.
If the TZT-701 requires warmed air, the word “Heating” will be displayed. If the room needs to be cooled, the word “Cooling”
will be displayed. If the Word “Heat” or “Cool” is slowly blinking the TZT-701 is waiting for a safety delay time to expire in
order to to protect the A/C system. When the blinking stops the cycle requested will commence.
Fan Running Animation.
A small animation of a fan revolving will be displayed whenever the air conditioning system fan is running. Note” all segments
of the fan animation icon are shown in the picture on page 5. In reality, when the TZT-701 thermostat is running normally, only
the parts of the LCD necessary to provide the fan running animation will be displayed.
Fan Speed Indicator.
The TZT-701 thermostat can control up to three speeds of indoor fan if the installer has enabled this function. The manually
selected fan speed is shown. Auto fan speed is shown by the three words “Low”, ”Med” & “High” in the LCD at one time. The
automatically selected fan speed will flash.
Fan Mode Indicator.
The TZT-701 thermostat can turn the indoor fan On & Off in a number of ways depending on whether the TZT-701 thermostat is
used in commercial or residential mode, or whether the TZT-701 thermostat is heating or cooling. This is displayed as “AUTO
FAN” or “FAN ON” mode. Pages 4 and 5 detail these functions.
Keyboard Lock Indicator.
The Padlock symbol will flash to indicate that parts of the keyboard are locked or the temperature control range is limited
preventing changes to the thermostat settings. The TZT-701 thermostat has multiple levels of keyboard lock for both manual and
programmable modes. See page 14 of the manual for more information on this function.
Active Zone Indicator.
“Zoning” allows you to split your heating and or cooling system into 2 separate temperature controlled areas or “Zones”. Each
can have their own temperature sensor (Optional Zone 2 sensor required). If zoning is enabled the Word “ZONE” and the
numbers “1” and or “2” will be shown in the LCD. If the optional Zone 2 sensor has been installed, the second zone temperature
will also be displayed and temperature control for that zone is provided. Refer to page 14 of this manual for more details.
Economy Mode Indictor.
If the outside air temperature is suitable, the TZT-701 thermostat will use the cooler outside air (rather than the warmer inside
air) to supplement the cooling capacity of your Air Conditioning system. If the outside air is very cool, then the TZT-701
thermostat may decide to stop the A/C system completely and only use this cooler outside air to cool the building. This reduces
running costs while improving the indoor air quality. The TZT-701 thermostat will inform you that it is using outside air by
showing the word “Economy” on the LCD. See page 13 for more detail on this feature.
