Selection of actuators, fans and sensors

Temperature Sensors: Use only our approved NTC sensors to achieve maximum accuracy.
Modulating Actuators: Choose actuators with an input signal type of 0-10VDC. The current on the output is
limited to 10mA.

Fan motors: Observe power limits and startup currents. Note: startup currents may be a multiple of the rated
current of a fan. Verify with the fan supplier if unclear.

Installation Terminal

1. Install the mounting plate to the electrical connection box. Make sure that the nipple with the front

holding screw is facing to the ground. Make sure the screw heads do not stand out more than 5 mm

of the surface of the mounting plate.

2. Connect the wires of the terminals to the communication wires according wiring diagram

3. Slide the two latches located on the top of the front part into the hooks of the mounting plate.

4. Lower the front part until located flat on the wall and the mounting plate is not visible anymore. Make

sure the connection cable does not get into the way.

5. Tighten the front holding screw to secure the front part to the mounting plate.

Connection base to terminal

 Max. Distance: 200m (565 ft.)

 Normal twisted pair copper wires maybe used for wiring in an EMC-save en vironment. In an

impaired EMC environment use only shielded cables. The operating voltage must comply
with the requirements for safety extra-low voltage (SELV) as per EN 60 730.

 1 terminal may drive up to 8 base units. See wiring for parallel connections . Total wire

distance should not exceed 200 m.

 Conductor resistance will influence external temperature reading. 450 Ω will result in an

increase of 1°C (2°F). Compensate using UP-08 if external temperature is used to control
unit.

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.

 Proportional control (P-band)

The proportional control function calculates the output based on the difference between setpoint and
measured value. The proportional band (P-band) defines the difference between setpoint and measured
value which will result in a 100% output. Setting the proportional band to 0 disables proportional control.

 Integral gain KI

The integral gain defines how fast the output increases in case the setpoint is not met by the room
temperature. A low value indicates a slow reaction, a high value a fast one. If the value is chosen too high,
the controller will start to swing. Depending on the room size and heating / cooling equipment used a value
between 0.1 and 1.5 should be sufficient. Below are suggested values:
Heating: KIH: 0.1-0.5, Cooling: KIC: 0.3-0.8

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 outp ut 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.

Switching
Economy and
Comfort modes

Economy (unoccupied) and Comfort (occupied) modes are controlled
through an external contact by connecting the input through a dry contact
to signal common. This function may be used together with key card
switches for hotels or motion detectors for offices.

FC24 = 3

Switching Energy
Hold OFF and
Comfort modes

Opening the input will force the unit into the OFF operation mode. The
operation mode cannot be overridden by using the terminal. Connecting
the input to signal common returns control of the operation mode to the
terminal. This function may be used as window contact to prevent loss of
energy.

FC24 = 4

Heat – Cool
changeover

Switch heating and cooling mode based on supply media or outside
temperature or binary contact. See below for further details.

FC24 = 5

Key card with
alternative
setpoint

As with FC24 = 2, 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 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.

FC24 = 6

Key card with full
reset

Similar as FC24 = 5 with the difference that setpoints, fan speed and
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.
