Configuration parameters for firmware version 1.3
The TCY-FT-U is preset to work for most applications. For special requirements it can be fine tuned to work
ideal with 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”).
Setting of user parameters
The TCY-FT-U can be adapted to fit perfectly into your application. The control operation is defined by
parameters. The parameters are set during operation by using the control buttons.
The parameters may only be accessed by entering a code. There are two levels of parameters: User
operation parameters for access control settings, and Expert parameters for control functions and unit setup.
The codes for user levels and expert levels are different. Only control experts should be given the control
parameter code.
The parameters can be changed as follows:
1.
Press UP and DOWN button simultaneously for three seconds. The display shows the software
version in the large digits and the product code in the small digits.
2.
Pressing the OPTION button will indicate CODE on the small digits and 000 on the large digits.
3.
The code for accessing the user parameters is 009
4.
Select this using UP or DOWN buttons.
5.
Press OPTION button after selecting the correct code.
6.
Once logged in, the parameter is displayed immediately.
7.
Select the parameters with the UP/DOWN buttons. Change a parameter by pressing the OPTION
button. Three triangles will show up on the lower right and indicate that the parameter may be
modified now. Use UP or DOWN buttons to adjust the value.
8.
After you are done, press OPTION or POWER in order to return to the parameter selection level.
Press the POWER button again so as to leave the menu. The unit will return to normal operation if no button
is pressed for more than 5 minutes.

CP 04
Economy (unoccupied) Mode temperature shift:
The comfort (occupied) setpoint is shifted by the value set
with parameter. If heating is active the comfort setpoint will
be decreased, if cooling is active, the setpoint will be
increased. (Enable with UP06.)

Dead Zone Span (TCY-FT4-U only):
The Dead Zone Span lies between the heating and the

Heat/Cool Changeover Delay (TCY-FT4-U only):
A demand to switch between heating and cooling must
persist for the length of time set with this parameter before
the controller switches. Prevents activation of a sequence

protect equipment (with control overshoot for example)

Configuring the function of the external input X1
The external input X1 may be configured for several functions:
CP18 = 0
External control
input
The control input is provided by the external input. The
internal input will not be used.
CP18 = 1
Switching Economy
and Comfort modes
Economy (unoccupied) and Comfort (occupied) modes
are controlled through an external contact by connecting
X1 through a dry contact to signal common. This function
may be used together with key card switches for hotels or
motion detectors for offices.
CP18 = 2
Switching Energy
Hold OFF and
Comfort modes
Opening the external temperature input will force the unit
into the OFF operation mode. The operation mode cannot
be overridden by using the terminal. Connecting the
binary input to GND returns control of the operation mode
to the terminal. This function may be used as window
contact to prevent loss of energy.
CP18 = 3
Key card function
As with CP18 = 1, the key card function switches
economy (unoccupied) and comfort (occupied) modes.
Instead of using the setpoint shift, the setpoints in
unoccupied mode are defined by parameter CP20 and
CP21.
CP18 = 4
Output enable
This may be used for a dew point sensor input. Output will
switch off if contact opens.
Configuring auto changeover input X2 (TCY-FT2-U only):
The auto changeover function automatically changes heating and cooling mode based on supply
media temperature or outdoor temperature. The difference between the two is in the values of the
changeover limits CP23 and CP24. See table below for recommended settings.
Heating and cooling may be as well changed by an open contact switched to signal ground. Note: all
signal ground levels of involved controllers must be the same in case more than one controller is
switched.
