Frequently Asked Questions - ECA 150 ipro B Maico

How to set the operating time after motion detection?

Use the right adjustment button (timer operating time) on the electronic cover. Press several times to select 0, 8, 17 or 25 minutes. The LED flashes twice to confirm.

The fan does not start, what to do?

First check the start-up delay (max. 120 s). Make sure the mains fuse is on. If the impeller is blocked, have it checked by a professional. In case of motor overheating, wait for cooling (up to 60 min).

Can this fan be used with a light switch?

Yes, optionally. The light switch can control the fan (on/off) with priority over the motion detector. The selected control program then applies.

What is the required drilling diameter for installation?

The minimum diameter is 150 mm. With a WH 150 wall duct, it is recommended to drill to 170 mm diameter.

How to clean the fan?

First disconnect the mains power. Clean the inside with a dry cloth. The protective cover can be removed and washed with water. Do not use aggressive products.

The fan stops by itself, is this normal?

Yes, the motion detector stops the fan after the set operating time if no motion is detected. Also check that the delay is not too short.

Can the sensitivity of the motion detector be adjusted?

No, the sensitivity is not adjustable. The range is 5 m with a horizontal angle of 100° and vertical angle of 82°.

What control programs are available?

Four programs: comfort (level 1 on presence, level 2 on timer), need (level 2 on presence, level 1 on timer), economic (level 1 always), power (level 2 always). They are set using jumpers J4 and J5.

Can this fan be used continuously?

Yes, but it will stop automatically after the timer if no motion is detected. For continuous operation, disable the auto-stop function or use a switch.

Where to find spare parts?

Spare parts (boards, covers, detectors) are available from Maico or authorized dealers. Refer to the manual for part numbers.

Further product features Unit versions [25].

Automatic humidity function

Once the fan is installed, it adjusts to the room humidity prevailing at that time (relative humidity). This humidity value is saved as the first reference value. The reference value does not have to be specified manually.

If the relative humidity falls below the reference value during operation, the newly established reference value is saved. The lowest possible reference value is 48% relative humidity.

When the room humidity increases

• If the room humidity increases by 7% , the fan switches on automatically at power level 1 (200 m^3/h ).
• If the humidity increases even further, the unit switches to power level 2 (250 m³/h).
• If there are no further increases, the fan continues to run at power level 1 (200 m³/h) until the humidity again falls below the saved reference value.

When falling below the reference value

• H and KH: Overrun operation starts with the set overrun time. The current reference value is then saved.
• RCH and KRCH: No overrun operation.

Value does not fall below reference value for 1 hour

• H and KH: Overrun operation starts. Fan then switches off.
• RCH and KRCH: Fan switches off.

Operation using light and/or radio switch

• H and KH units can also be operated using the light switch. With "Light on", the set operating programme starts with the start delay Operating programs [30] The operating program takes priority over the automatic humidity function. After switching off, the unit continues to run until the remaining overrun time has passed. The automatic humidity function is then assigned maximum priority again and controls the unit as described above.
• Optionally, RCH/KRCH units can be operated in 2 levels using a radio switch. Switching through the DS RC or window contact is possible during humidity operating mode.

5.8 MAICOsmart system description

MAICOsmart network with radio electronics

• Receivers are ECA 150 ipro fans of the RC, RCH, KRC and KRCH unit models.
  Transmitters are system components such as

• RLS RC room air controls

• DS RC radio switches

• radio window contacts
  ECA 150 ipro RC, RCH, KRC and KRCH

• All the ECA 150 ipro RC models can be combined with each other in the network.

• ECA 150 ipro RCH and KRCH fans also have humidity control (fully automatic humidity control).

• The MAICOsmart system can be operated with a radio switch and/or the RLS RC room air control:

• The two power levels can be selected or the system can be switched off with a radio switch.

• With the RLS RC room air control, the three system levels can be switched on manually ( table in chapter Operation [35]).

• This function is deactivated ex works in order to guarantee continuous ventilation. If need be, this function can also be activated ( RLS RC room air control installation instructions).
  The fan can also be switched on/off with radio window contacts (window open/closed).

• During commissioning, the transmitters must be taught-in on the receivers (must be paired with each other).

Further radio components

DS RC radio switch (EnOcean switch)

A: Fan with a radio switch in individual operation.

• Radio switch, (double rocker switch) for setting different fan power levels.
• Press the rocker switch to switch up or down one power level.

The left and right rocker switch have to be taught-in separately: Left rocker switch for on/off, right rocker switch to switch the ventilation level up and down.
Always teach in the radio switch for the fan that is located in the same room as the switch.

B: Fan with several radio switches in individual operation.

Function as described above. Up to 5 radio switches can be taught in per fan.

Radio switches in master/slave network

The ventilation system is operated according to the settings made on the RLS RC. However, every switching action made by radio switch has priority over the RLS RC setting.

• If a radio switch is operated, the assigned fan switches to the manually selected power level.
  After 30 minutes of the switch not being operated (timeout), the unit returns to the setting according to RLS RC. If the setting is changed on the RLS RC during the timeout, the assigned fan only reacts to this command once the timeout has elapsed.

• In the case of RCH/KRCH units, the automatic humidity function operates with priority. Switching through the DS RC or through a radio window contact is possible during humidity operating mode.

Radio window contact (EnOcean switch)

• Radio window contacts can be taught-in for each fan.
• The radio window contact sends the Window open or Window closed status to the assigned fan.
• The assigned fan switches off automatically if the window is opened.
• If you want the fan to continue to operate even when the window is open, it can be switched on with the assigned radio switch.
• The radio switch has priority over the radio window contact and/or the RLS RC.
• The fan switches off again after a timeout of approx. 30 minutes (if the window is still open) or back to the operation mode set on the RLS RC (if the window is closed).
• In the case of RCH/KRCH units, the automatic humidity function operates with priority. Switching through the DS RC or window contact is possible during humidity operation.

RLS RC room air control (EnOcean radio control)

For information about the RLS RC room air control, see separate installation instructions.

• The RLS RC room air control is a radio control for the manual operation of master and slave devices.

• Two programs (P1/P2) with different power level combinations are available for operation.
  The programme suitable for the application (P1 for small/P2 for large residential units, tables in chapter Operation [35]) is determined during commissioning.
  The following appears in the RLS RC display: System level 0/Off without bar System level 1 with two bars System level 2 with 4 bars System level 3 with 6 bars
  The time and temperature are also shown on the display.

• The holiday mode is equipped with interval operation. The on-off change takes place every 30 minutes for all fans (humidity protection). Radio commands from further radio network devices are ignored until holiday mode is switched off.

• Service menu for system settings.

9.1 Procedure

For information on the function and program levels MAICOsmart system description [26].

To teach in an RC fan, remove the housing cover and then reattach it Preparation for installation [28].

Operation with stand-alone fan

1. On the fan, first teach-in the RLS RC room air control and then the radio switches and/or radio window contacts.
2. Teach-in further system components.
3. Perform function test with all system components.

Master/slave network

1. First teach-in the pre-configured RLS RC room air control on the master fan.
2. Then teach-in the radio switches, radio window contacts and further slave fans.
3. Teach-in radio switches and radio window contacts on the slave fans (max. 2 fans).
4. Carefully press the housing cover (incl. designer cover) onto the housing, until it engages with the safety catches.
5. Perform function test with all system components.

9.2 Tips for teaching-in radio components

A fan automatically becomes a master if the master fan is set to receive mode and a teach-in telegram is received from a slave fan.
If a master fan is accidentally taught into a slave fan, the master assignment ceases to exist (master fan becomes a slave fan). This can result in having to re-enter all system components.

• A fan becomes a slave fan if it transmits a teach-in telegram to the master unit and the master unit confirms this telegram.
• If the RC master or slave fan receives a valid teach-in telegram from a radio component that has not yet been taught-in, the data is evaluated and stored.

• If the radio component has already been taught-in, the teach-in telegram is deleted, that means that the teaching-in must be repeated.

• If there is no reception within 60 seconds, the teaching-in is terminated and the LED on the fan switches off. The procedure must be repeated.

• Teach-in telegrams from non-supported radio components are ignored.
