Display and operation
Operation Modes
STEP
Normal mode
The ventilation is operating based on selected values
OFF
Absence mode
Ventilation is operated with on and off intervals. The intensity and
duration of both on and off intervals may be defined with parameters.
The default is 5.5 hours in off mode and 0.5 hours with minimum airflow.
Party mode (FULL)
Ventilation is fully activated. The reset time is shown on the display. It
may be set.
HIGH
Full supply mode
This mode is activated by an external input for example a switch on the
kitchen or bathroom exhaust fan. The Supply air opens full and the
return air is switched off. The values of full supply mode for both supply
and return air are selectable through parameters.
Time schedule mode
Airflow is defined by time schedules
Manual override
Short term manual override of the time schedule value. After a fixed
reset time of 60 min the positioner will revert to the scheduled value.
Power Failure
All the parameters and set points are memorized and do not need to be reentered. Depending on UP03 the unit will
remain switched off, switch on automatically or return to the operation mode it was in before the power failure.
Deluxe version only: Timer operation and daytime setting will be retained for 24h. The controller has to be connected to a
power supply for at least 10 hours for the backup function to operate accordingly.

Clock operation
The TCT-MZ2-D contains a quartz clock with battery back-up (not available in TCT-MZ2). Up to 8 switching events based
on time and day of the week may be programmed. A switching event is defined by the time, day of the week and
ventilation setpoint.
A blinking clock indicates that the time has not been set or that the unit has been without power for longer than 48 hours.
The time needs to be set to allow time schedules to operate.

Configuration
Doc: 70-00-0588 V1.0, 20180928 © Vector Controls GmbH, Switzerland Page 6
Subject to alteration www.vectorcontrols.com
Configuration
The TCT-MZ is preset to work for most applications. However, it can be fine-tuned for special requirements through a
simple parameter setup routine. The parameters can be changed on the unit without the need of additional equipment.
Identifying the firmware version
The parameters and functionality of controller depend on its firmware version and revision. It is therefore important to use
a matching product version and parameter set. The Firmware version and revision version can be found when pressing
simultaneously the and keys during several seconds. On the upper 7 segment display, the firmware version can be
found, on the lower 7 segment display the current revision index (or “sub-version”).
Access to parameters
The parameters can be changed as follows:
1. Press UP and DOWN button simultaneously for three seconds. The display will indicate the firmware version in the
upper large digits and the revision in the lower small digits. Pressing any key will show: CODE.
2. Select a password using UP or DOWN buttons. Select 009 in order to get access to the user parameters
Press OPTION after selecting the correct password.
3. Once logged in, the parameter is displayed immediately
4. Select the parameters with the UP/DOWN keys. Change a parameter by pressing the OPTION key. The MIN and
MAX symbols show up and indicate that the parameter may be modified now. Use UP and DOWN key to adjust
the value.
5. After you are done, press OPTION or POWER in order to return to the parameter selection level.
6. Press the POWER key again so as to leave the menu. The unit will return to normal operation if no key is pressed
for more than 5 minutes.

Signal limitation for VAV systems
The minimum and maximum airflow limits may be adjusted directly on the controller. A setup on the VAV
actuator is thus not required.
Absence mode
The ventilation is activated during absence mode in selectable intervals. High and Low time as well as high and
low levels of the absence mode may be defined. Per default a low time of 5.5 hours with energy hold off level is
followed by a high time of 0.5hours with minimum air flow. During energy hold off level, the ventilation is off.
Configuring the function of the external input X1
Normal –Absence mode changeover
The operation mode can be controlled through an external contact. If the contact is closed (input connected to
signal ground), normal mode is activated. If the contact is open for a time defined in CP10, absence mode is
activated. Pressing the LEFT button reactivates normal mode and resets the countdown timer defined with CP10.
A possible application is a motion detector for an office or meeting room in series with a window contact.
Full supply mode
If the contact closes, the supply air will be set to maximum (defined in CP11) and the return air set to OFF
(CP12). This function is used for kitchen exhaust or bathroom exhaust fans to prevent negative indoor pressure.
A delay may be defined with CP10.
