1 Safety regulations

1.1 Safety

Only allow correspondingly trained, qualified and skilled personnel to carry out installation work.

Reliable operation and the avoidance of damage and hazards are only guaranteed if installation and settings are carried out carefully in accordance with these instructions.

There may be personal danger by electrically operated windows:
– the forces occurring in the automatic mode can be such that parts of the body could get crushed
– when opened, actuators (spindles) could protrude into the room
For this reason, measures have to be taken prior to starting up the actuators, which exclude the danger of injury.

For safety reasons we recommend installing opening restrictors on bottom-hung windows.

In the event that windows are subjected to rain and/or high wind loads, we recommend connecting a wind/rain sensor to the MotorController for the automatically closing of the windows.

The MotorController is to be located in a safe place, protected from the effects of fire and smoke.
The MotorController is to be surface mounted.
The MotorController is supplied by 230V AC.
The manufacturer does not assume any liability for possible damage resulting from inappropriate use.

1.2 230V AC

230V AC can cause death, severe bodily injury, or significant damage to property.
The MotorController must be disconnected from the power supply before being opened, mounted, or performing any alteration of the construction.
Power supply to the MotorController must be done via external two-pole or multi-pole circuit breaker. The MotorController is to be supplied with Phase conductor, Neutral conductor and Earth conductor

Applicable national regulations must be complied with.

1.3 Application

The MotorController is solely designed for the automatic opening and closing of windows, flaps and doors.
Always check that the system complies with applicable national regulations.
The cable cross section will depend on wire length and power consumption. See chapter “Cable dimensioning”.

1.4 Cabling and electrical connection

WindowMaster recommends powering the MotorController from its own group.
Cable routing and connection – adhere to national regulations.
Establish the cable types, if necessary, with the local approval bodies.
Do not conceal flexible cables.
Junction box must be accessible for maintenance purposes.
Disconnect all poles of the mains voltage prior to starting maintenance work or making changes to the system.
Secure the system to prevent unintentional switching on again.

Route all low voltage cables (24VDC) separate from the power current cables. Design cable types, lengths, and cross sections in accordance with the technical information. Cable specifications is a guide only, the overall responsibility resides with the electrical contractor on site. Installation must be in accordance with the national electrical regulations.

2 Introduction to WCC 106 A

WCC 106 A is a MotorController that controls (opens/closes) 1 or more ±24V standard or MotorLink® window actuators on the basis of a signal from the remote-control type WCA 100, the App “Fresh Air Control”, connected comfort keypads or the connected components, e.g., room sensors and weather sensors.

2.1 The MotorController’s construction

The MotorController contains a 150W primary power supply (SMPS – switched mode power supply) and a printed circuit board with input, output, and auxiliary supply (AUX).

WCC 106 A has 2 motor lines to which ±24V standard actuators or MotorLink® actuators can be connected; the number of connected actuators depends on the actuator type; the following table lists the max number of actuators. Total power consumption for all connected motors incl. load on X7 (AUX max 0.5A) may not, however, exceed 6A.

If internal coverings are removed the live current parts are exposed.

Guidelines for mounting / installation

• the MotorController should be mounted on the wall in such a way that there is free access for service inspections
• adhere to the installation instructions and your local energy providers
• select the place of installation such that free access is guaranteed for maintenance purposes
• select cables according to regulations in this instruction – take the calculation of the actuators supply cable lengths into account when laying the cables
• connect the cables in accordance with the drawings provided by the manufacturer
• route the cables in the building according to the regulations in this instruction
• check all system functions

7 Cable dimensioning

Cables should be routed in compliance with applicable regulations.

7.1 Max. cable length

The maximum permitted cable lengths from the MotorController to the actuators, taking into account the cable cross-section, are shown in the following table.

7.1.1 Formula for calculating max. actuator cable length

Max. cable length =

permitted voltage drop 2V (UL) x copper’s conductivity (56) x cable cross-section in mm² (a)

Max. total actuator current per motor line in amperes (l) x 2

For ±24V standard actuators, the cable cross-section may not be less than 0.75 mm², irrespective of the result of the above formula.

Maximum actuator cable length: Always measured from the MotorController to the last junction box + actuator cable
Permissible max. voltage drop in the line: 2 Volt
Total actuator current: The sum of all the connected actuators max. current consumption per motor line
Note: do not use the PE wire / green/yellow wire in the actuator cable!

Example
Max. actuator cable length with cable cross-section of 0.75mm² and 2A current consumption: (2 x 56 x 0.75) : (2 x 2) = 21m

7.1.2 Max. cable length – ±24V standard actuators

The actuator cable must have 2 wires minimum.

7.1.3 Max cable length – actuators with MotorLink®

The actuator supply cable must have 3 wires: 2 wires current carrying / 1 wire for communication.

When a 5-wire cable is used for MotorLink®

It is not recommended to use parallel-wire.

ML-comm = MotorLink® communication.

Furthermore, when using a 5-core cable, the distance between ”–” and ”Com” must be the same as the distance between ”+” and ”Com”.

Meaning if L2 e.g. is being used as ”Com” L1 and L3 must be used for ”+” and ”-”.

When using actuators with MotorLink® the max/total cable length is 50m regardless of the result of the above mentioned formula.

Actuators with MotorLink®

Definition of total cable length

The total cable length is defined as the sum of all cables from the MotorController output to the last actuator. Including the cable mounted on the actuator.

For example, in case of 4 actuators with 5m cable each, the remaining cable length is 30m.

Example 1

Total cable length = L1 + L2 + L3 + L4 + L5 + L6 + L7 = 10m + 5m + 10m + 5m + 10m + 5m + 5m = 50m

Example 2

Total cable length = L1 + L2 + L3 + L4 + L5 = 30m + 5m + 5m + 5m + 5m = 50m

10 DIP switch configuration

The MotorController has 8 DIP switches for easy configuration. The factory setting for the DIP switches is OFF.

DIP switch| Description on the MotorControlleren| DIP switch position
---|---|---
1| Maintained action| ON: the actuators open/close completely when the comfort keypad is pressed.

OFF: the actuators run for as long as the comfort keypad is being pressed.

2| Rain delay| ON: the rain signal must be active min. 60 sec. before the actuators begin to close.

OFF: the actuators begin to close as soon as the rain signal is activated.

3| Extended hand timer| ON: after manuel override the actuators are locked for 2 hours (except rain/safety signals).

OFF: after manuel override the actuators are locked for 30min (except rain/safety signals).

4| Surveillance| ON: activate cable surveillance on input X10.1 (rain). The Input must be terminated with 10k resistor.

OFF: no cable surveillance.

5| MotorLink®| ON: MotorLink® motors are connected to the MotorController.
It might be necessary to reset the MotorController when activating this DIP switch. OFF: ±24V standard motors are connected to the MotorController.
6| 100% speed| ON: actuators run with 100% speed, when run manually.
(this setting requires MotorLink® actuators and that DIP switch 5 is set to ”ON”) OFF: actuators run with 75% speed, when run manually.
7| Accumulated step| ON: actuators open/close in steps, when a thermostat e.g., WLA 110 is connected to the MotorController and the setpoint is exceeded.

Opening step: 5% for every 5min
Closing step: 10% for every 10min

OFF: actuators open/close completely when a thermostat e.g., WLA 110 is connected to the MotorController and the setpoint is exceeded

8| ML 2, motors run independently| ON: the actuators on motor line 2 are controlled individually via input X2, X3, X4 and X5.
Up to 4 actuators can be connected to motor line 2 and all actuators must be single / -1 actuators.
The actuator’s serial number determines, which input controls which actuator, the serial number is automatically identified by the firmware in the MotorController.

X2 – controls the actuator with the highest serial number
X3 – controls the actuator with the second-highest serial number
X4 – controls the actuator with the second-lowest serial number
X5 – controls the actuator with the lowest serial number

The actuators can be identified by activating the different inputs.
The serial number can also be read on the product label on the actuator.

Actuators on motor line 1 are controlled together via input X10. Up to 4 actuators can be connected to motor line 1. All actuators on motor line 1 must be of the same type, incl. team size and chain length. The actuators must be either single /-1 or quad /-4.

All connected actuators on both motor lines must be MotorLink® actuators and DIP switch #5 must also be set to ON.

This DIP switch setting does not influence how the actuators on the two motor lines are controlled via the remote control.
(this setting requires MotorLink® actuators and that DIP switch 5 is set to ”ON”)

OFF: 2 Motor groups with a motor line each

11 Control via remote control – WCA 100

The window actuators connected to the MotorController can be controlled (opening and closing) with the remote control type WCA 100.

The remote control has an operation range up to 50m outside and 10m inside.
Physical barriers such as walls, cabinets etc. will reduce the operation range.

 The remote control has 3 buttons, each with 3 keys (functions) – OPEN, STOP and CLOSE.

ML = motor line

A short blink on the remote control’s green LED indicates that the command from the remote control to the MotorController has been received by the MotorController.
A short blink on the remote control’s red LED indicates that the command from the remote control to the MotorController has not been received by the MotorController.

11.1 Before use

The remote control is supplied with 2 x AAA batteries, which must be inserted before use.
Furthermore, the remote control and the MotorController must be paired with each other before the remote control can operate the actuators connected to the MotorController.

11.1.1 Pairing of remote control and MotorController

To avoid any disturbances the remote control must be held close to the MotorController during pairing. Only activate pairing mode on one MotorController at the time, otherwise, the remote control will pair with the MotorController with the strongest signal.
A remote control can only be paired with one MotorController.

MotorController

1. Activate pairing mode on MotorControlleren by pressing K5 (pairing button) on the MotorControlleren.

Remote control
The remote control differs between two different presses; a short and a long press.
The short press is used for normal/daily operation, meaning control of the window actuators. The long press is used for the pairing process.

Short press: the press lasts max. 3 sec.
Long press: the press lasts min. 3 sec

1. Activate pairing mode on the remote control, by pressing simultaneously on key #3 and #9 – see above ”Button and key function overview”. The press must be a long press on both keys meaning min. 3 sec.
   When the remote control is in pairing mode it starts blinking first red and then green double blinks.

2. As the remote control only can be paired with one MotorController, the remote control automatically deletes any previously paired MotorControllers before it starts the pairing process with the desired MotorController.

3. The remote control starts a scanning process to identify the desired MotorController, which also must be the one closest to the remote control.
   On the remote control, the scanning is indicated by the green LED, which every second blinks two short blinks.

4. a) The LED on the remote control blinks one long green blink. The pairing process was a success, the remote control and the MotorController is now paired.
   b) The LED on the remote control blinks one long red blink. The pairing process failed.

The pairing process succeeded:

The MotorController and remote control are now ready for use. Carry out a test run, if this is the MotorController’s first pairing, see chapter “Commissioning and test run”.

The pairing process failed:

– Ensure that the batteries are inserted correctly into the remote control.
– Ensure that the MotorControllere has been connected to 230V and that pairing mode is activated.
– Ensure that MotorController and remote control – during the pairing process – are close to each other and that there are no disturbances between them, such as walls, furniture etc.
– Replace the batteries in the remote control.
– Repeat the pairing process.

If the pairing process continues to fail please contact your local WindowMaster office.

12 Control via app – Fresh Air Control

The windows can also be controlled via app. The MotorController must be version 02 or higher for the app to be used.

The app ”Fresh Air Control” can be downloaded from Google Play or App Store.

The app can connect to several MotorControllers. WindowMaster recommends connecting max. 5 MotorControllers to a smartphone/tablet and max. 5 smartphones/ tablets to a MotorController.

13 Status and troubleshooting via LED on the MotorController

In the event of failure/error of the MotorController one or more diodes will light and/or blink.
On the WCC 106 A there are 4 diodes – 3 green and 1 yellow – that can indicate errors and status on the MotorController.

Irrespective which diode lights or blinks, the indicator is based on a 3.2 second sequence that is repeated continuously. Each sequence is defined by 32 x 0.1 second time segments.

If there are several errors on the MotorController simultaneously they are displayed by priority, i.e. error messages for the most critical failures are shown first and repeated until the failure is remedied. Then error number two is shown, which likewise is repeated until the error is remedied etc. The following overview shows the most frequently occurring errors, if an error other than those listed below is indicated, contact WindowMaster.

Yellow diode – LED 1
If the yellow diode lights, this indicates an error on the MotorController.
Black = diode off

No Error 

Error indicator on the yellow diode is a total errors indicator. Detailed information on the error type can be decoded on the green diode.

Green diode – LED 2
If the green diode LED 2 (closest to X10) blinks, this indicates the error on the MotorController.
Black = diode off

14 Commissioning and test run

In the event of error messages, refer to chapter “Status and troubleshooting via LED on the MotorController”.

14.1 MotorController fully installed, without operating power

1. Check all mechanical and electrical components for damage.
2. Check all screw and plug connections for tightness and/or firm seating.
3. Check that all external components are installed; check polarity for the ±24V actuators

14.2 With network power

Adhere to the relevant regulations!
Connect the mains cables and reapply the mains voltage.

14.3 Remote control and comfort keypad

Look closely at the actuators as they open and close – there must not be any obstacles in any position and the actuator connection wires must not be overstrained with pulling or pinching.
Test the remote control and every single comfort keypad if installed.

14.4 Wind/rain sensor

1. Open the actuators with the comfort keypads.
2. Dampen the rain sensor, the actuators close completely.
3. While the actuators are running, press Open button on the comfort keypad. The actuators must neither open nor stop.

If commissioning proceeds correctly, the lid of the MotorController may be fitted.

If commissioning does not proceed correctly, i.e. there is an error in one of the test points, refer to chapter “Connection description”
If necessary, re-test the cable routing in accordance with chapter “Connection plan for WCC 106 A”.
