Operation terminal OPU-D42-W50
Configuration parameters for firmware version 2.0 –W50
This controller can be adapted to wide variety of fan coil applications. The adaptation is done with
parameters. 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 revision. It is therefore important to use
a matching product version and parameter set. The firmware version is shown on the large LCD digits when
pressing UP and DOWN buttons for more than 3 seconds simultaneously.
Changing parameters
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 software revision 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. The MIN and MAX symbols show up 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.
9.
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.

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.)

Switching Hysteresis is the difference between
switching on and switching off. A small hysteresis will
increase the number of switching cycles and thus the
wear on fan and relays contacts.

Level to activate binary output if in dual AO-DO mode:
Dual AO-DO mode = both analog and binary outputs
are assigned to same control sequence.
FC 23
Level do deactivate binary output if in dual AO-DO
mode
Dual AO-DO mode = both analog and binary outputs
are assigned to same control sequence.
The three fan outputs are assigned to the fan speed module. Only output 4 can be assigned by this
parameter (FC21). Select if the binary output should work as controls output in heating or cooling only
or both for heating and cooling mode.
Dual AO-DO mode: if both the analog and the binary output is assigned as control output to the same
sequence, the binary output will then switch on when the analog output reaches the value defined in
FC22 for example 95% and switch off when it drops below FC 23 for example 45%. Note: This output
does not follow min running and stopping delays. It only reacts to the conditions mentioned above. In
order to take advantage of this function we recommend using larger proportional bands.

setpoint
setpoints in unoccupied mode are defined by parameter FC26 in heating
mode and FC27 in cooling mode.
Fan speed in unoccupied mode is limited to low speed.
Fan speed and setpoint will be remembered after re-inserting the key card.

operation mode are reset each time the key card is inserted. This is helpful
for business hotels. Setpoints will be reset to FC28 or FC29.
Configuring auto changeover input if FC24 = 4:
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 FC26 and FC27. 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.
