Located next to the DIP switches is the Fault Logic switch. It is vital that you set this to suit the operation of the TWO “Fault / Occupancy” inputs on the TZT-701. There are two inputs – “Fault C” and “Fault V”. Read more about these inputs on page 10 of this manual.

Seal any holes where cables enter the back of the thermostat. The TZT-701 wall controller must be wired to the main PCB fitted in the air conditioner using 4 core screened cable ONLY.

As a consequence of this advanced zone management method there may seem to be unusual delays before heating or cooling starts. The TZT-701 has time delays in place that provide adequate time for zone dampers to move to their correct position prior to starting the heating or cooling.

Note: Some brands of zone dampers cannot be wired in parallel due to “damper feedback”. Damper feedback will cause the dampers to continually move open and closed regardless of the TZT-701 relay status. Check with your damper provider to ensure suitability for parallel connection before using a damper in this way.
Note:- In almost all but a few cases will the functions in this menu need to be altered from their default state. The TZT-701 has a PIN protected menu that permits the installer to “fine tune” the TZT-701 for the specific requirements of the installation or to enable / disable advanced functions as required for the project.

This feature is useful in installations where the air conditioning should only run for a limited time, or where an area is used infrequently – such as training rooms for example. The installer can set an Auto Off time, so that “XX” hours after the TZT-701 is turned on it will automatically switch itself off again.

The TZT-701 can control both heating and cooling systems. However, there may be situations where the TZT-701 is to control a Heating only system, or a Cooling only system. In these circumstances the TZT-701 can be set to heat only or to cool only modes to eliminate user confusion.
A green LED is fitted on the main PCB and labelled “System OK”. If this LED is not lit, then a fault condition exists from either of the fault inputs or an internally detected TZT-701 fault. When a fault is detected the fault relay will deactivate and the Green “System OK”...

LED indicators All relays on the TZT-701 are identified by printing on the PCB. To assist with diagnostics each relay coil has a LED in parallel so that when a relay coil is energised, the associated LED will be on.

Once the correct operation of the Heating & cooling system has been verified testing of the zoning (if installed) must be completed. The simplest way to accomplish this is to turn the TZT-701 to Fan only mode and tap the on/off button to select Zone 1 only.
