Introduction
temperzone’s TZT-701 thermostat is able to manage your comfort levels in a number of ways. Your installer should have
programmed your TZT-701 thermostat to specifically suit the unit it is controlling and the requirements of the building.
If after reviewing this manual, you consider there are features or functions that you consider desirable, which are not activated on
your thermostat, please contact your installer or an authorised temperzone service agent for advice on adding these functions.
To assist with the clarity of the manual, it has been divided into the following 5 main sections.
• Common Functions.
This part of the “User Manual” explains the functions available regardless of the thermostat mode set by the installer .
• Residential Programmable Mode.
This section of the manual explains how to use the TZT-701 when installed in a home or apartment. It contains information on programming the
thermostat, using zone control (if installed), and how to get the most from your air conditioning system.
• Commercial Programmable Mode.
When using the TZT-701 thermostat in a commercial building special functions are available. Capabilities such as afterhours run timers,
outside air economy control and other commercial air conditioning management capabilities are detailed in this section.
• Manual Mode (can be used in either residential or commercial buildings).
Often programming or fully automatic air conditioning control is not required. In these circumstances the installer will have set the TZT-701
thermostat for manual mode. This mode is the easiest mode to use the air conditioning system in, but it will not automatically turn the A/C
system off (or change the set temperature) at the end of the day.
• Advanced functions.
Your air conditioning system has some advanced control and energy management features. This part of the manual explains these capabilities
to help you better understand why your air conditioning system and TZT-701 thermostat is behaving the way it is.
Common Functions
Selecting Heating, Cooling and Auto Modes.
With each tap of the MODE button the TZT-701 thermostat will cycle through Heating only mode, Cooling Only mode, Auto
mode and Fan only (ventilation) modes. These modes are described in more detail below.
Please Note: To suit your air conditioning system type, either the Heating or Cooling function may have been disabled.
Heat Only Mode - The TZT-701 thermostat will activate Heating when the room temperature falls below the Heat set point
temperature by 0.5°C. In Heat-Only mode the TZT-701 thermostat will NOT bring on Cooling regardless of the room
temperature and set point. In Heat-Only mode, only the word “Heat” will be displayed in the LCD. When your air conditioning
system is actively heating, the word “Heat” in the LCD will change to the word “Heating”. If “Heat” is flashing in the LCD, the
TZT-701 is waiting for its anti-rapid cycle delay to expire prior to starting “Heating”.
Cool Only Mode - The TZT-701 thermostat will activate Cooling when the room temperature rises above the Cool set point
temperature by 0.5°C. In Cool-Only mode the TZT-701 thermostat will NOT bring on Heating regardless of the room
temperature and set point. In Cool-Only mode, only the word “Cool” will be displayed in the LCD. When your air conditioning
system is actively cooling, the word “Cool” in the LCD will change to the word “Cooling”. If the word “Cool” is flashing in the
LCD the TZT-701 is waiting for its anti-rapid cycle delay to expire prior to starting “Cooling”.
Auto Change-Over Mode - The TZT-701 thermostat will commence “Heating” if the room temperature falls below the Heat set
point by 0.5°C. Conversely “Cooling” will commence if the room temperature rises above the Cool set point by 0.5°C.
Auto Change-Over mode is indicated by both the words “Heat” & “Cool” in the LCD. If the word “Heat” or “Cool” is flashing in
the LCD the TZT-701 is waiting for its anti-rapid cycle delay to expire prior to starting the air conditioning system.
Fan Only. If Fan-Only is selected the TZT-701 thermostat will turn on the Indoor fan for continuous operation. The TZT-701
thermostat will not activate heating or cooling regardless of the room or set point temperature(s). If Fan-Only is chosen the words
“Heat” or “Cool” are NOT shown in the LCD. In Fan Only mode the fan will operate 100% of the time. Fan-Only mode is
typically used for ventilation purposes. Each press of the FAN button will step through the available fan speeds.
Fan Control Logic
Auto Fan Mode
If Auto Fan mode has been selected by pressing the “FAN” button the indoor fan will turn on when the heating or cooling turns
on, and off again once the heating or cooling turns off. To prevent cool drafts occurring when the heating first starts, the fan may
delay starting for a brief period to permit your air conditioning system to pre-warm. To conserve energy your fan may continue
to run for a short while after the heating or cooling has stopped.
