  • Page 4: Installation

    Time taken during this installation process will be rewarded with a happy customer and fewer call-backs. The steps required to install the TZT-100 thermostat are - Read and understand this manual and the User manual. Mount the TZT-100 back plate in a suitable location.

  • Page 5: Mounting The Wall Controller

    Mounting the TZT-100 thermostat. The TZT-100 can only be as accurate as the onboard temperature sensor, or its optional remote temperature sensor(s) permit. It is therefore essential that the TZT-100 be installed in a location that is typical of the ambient room temperature. Do not install the thermostat in a draft, near a floor, behind doors or on a non-insulated external wall.

  • Page 7 Switch 1 – Relay Assignment The TZT-100 is fitted with 5 relays capable of switching up to 24VAC @ 1Amp each. Switch 1 sets the function of these relays as either 3 fan speeds with 1 heat and 1 cool operation or single fan speed with 2 heat and 2 cool, in either HP (heat pump / reverse cycle) or HC (heat with add on cool) mode.

  • Page 9: Tt Terminal Functions

    TT Terminal Functions The TZT-100 is fitted with a set of terminals marked “TT”. Details of the “TT” terminals functionality is provided below. See the advanced installer setting menu on page 25 of this manual for setting the function of this set of terminals.

  • Page 10: Outside Air Sensor Wiring

    Figure 1 for correct operation. Using a single pair of wires connect the “TT” terminals in the TZT-100 to the two terminals in the outside air temperature sensor. (See Figure 1). If the outside air sensor fails two dashes will be shown on the LCD where the outside air temperature would normally be displayed to alert you of the problem.

  • Page 11: Averaging Temperature Sensors

    The TZT-100 can be connected to an external dry contact. When this contact is closed the TZT-100 will turn OFF. (See Figure 3.) When the TZT-100 has been switched OFF via the “TT” terminals the word “OFF” will flash in the LCD to indicate that this has been the shutdown method.

  • Page 12: Supply Air Temperature Monitoring

    In this mode, the TZT-100 will ONLY broadcast this sensor temperature value via its ModBus communication. This value is not used by the TZT-100 nor is it displayed on the LCD. It is expected that this information is used for supervisory functions or equipment control feedback.
