Merlin Commander Extreme MS125MYQ

The Merlin Commander Extreme MS125MYQ is a sectional garage door opener designed for residential sectional doors up to 20 m². It is equipped with a battery backup system and is compatible with myQ technology, allowing for smart control and monitoring of your garage door.

Function Description

The Commander Extreme MS125MYQ operates by driving a chain or X-rail system to open and close the garage door. It features programmable travel limits, which define the door's stopping points in both the UP and DOWN positions. The opener also includes an automatic force setting that adjusts to the door's movement, ensuring safe and efficient operation. In cases where manual force adjustment is needed, a manual learn mode is available.

A crucial safety feature is the safety reverse system. The door is designed to reverse on contact with a 40 mm obstacle placed on the floor, preventing serious injury or property damage. Regular testing of this system is essential. The opener also supports the optional "The Protector System™" (IR Beams), which creates an invisible beam across the garage door opening. If this beam is broken while the door is closing, the door will reverse to the open position, providing an additional layer of safety, especially for homes with young children. This system is strongly recommended for all installations and is mandatory when the closing force exceeds 400 N (40 kgf) or when operating in SLOW speed mode for doors over 150 kg.

The opener can be activated using various devices, including the opener control panel (UP and DOWN buttons, Green O.S.C.), an outside keyswitch or keyless entry system (if installed), and remote control transmitters. The courtesy light on the opener illuminates when activated, when power is restored after an interruption, or when initially plugged in, and turns off automatically after 2.5 minutes.

Usage Features

The Commander Extreme MS125MYQ offers several features to enhance convenience and safety:

Manual Release: In case of power failure or emergency, the manual release mechanism allows the garage door to be operated by hand. To disengage, pull the red manual release rope and handle down. To re-engage, pull the rope towards the motor until it springs back to its horizontal position. It's important to use the manual release only when the door is closed, if possible, and to ensure no one is in the doorway when disengaging. The release handle should be mounted at a height less than 1.8 m from the floor.
Travel Limits Programming: The travel limits are set using the UP and DOWN arrow buttons and the PROG button on the control panel. The opener uses a position tab on the chain that activates a mechanical passpoint during door travel, indicated by a blinking LED. The door's UP and DOWN positions can be precisely adjusted to ensure adequate clearance and proper closure.
Force Setting: The opener automatically sets the force required to operate the door. However, a manual learn mode is available if needed. This involves pushing the yellow Learn button twice, then using a remote control or the UP/DOWN arrows to cycle the door through a full UP and DOWN cycle.
Travel Speed Selection: The opener offers two travel speeds: NORMAL and SLOW. The factory default is NORMAL speed. SLOW speed is recommended for doors with a total mass exceeding 150 kg, and "The Protector System™" must be installed when SLOW speed mode is selected. The speed can be toggled by pressing and holding both the UP and DOWN arrows for 3 seconds.
Low Standby Mode (Optional): This feature, activated by default, minimizes power consumption (sub 1 watt) when the door is closed and the courtesy light is off. In this mode, external accessories power and IR Beams are turned off. Normal Standby Mode can be activated to provide continuous power to external accessories.
Transmitter Programming: Remote control transmitters can be programmed to operate the opener and its courtesy light. The "LEARN" button on the opener is used for this process. Multiple transmitters can be programmed, and all remote control codes can be erased if needed.
Wireless Wall Button (E138M): This accessory can be programmed to operate the opener. It should be installed at a minimum height of 1.5 m above the floor and out of reach of children.
Timer to Close Feature (TTC): This optional feature automatically closes the door from a fully open position after a specified time (10 to 180 seconds in 10-second increments). It requires "The Protector System™" (IR Beams) to be installed. If an obstruction is encountered during closing, the door will stop and return to the UP position, and the courtesy lamp will flash 10 times.
Partial Opening Feature (PET): This adjustable second stop position is suitable for ventilation, pedestrian, or pet access. It can be programmed to a remote control button, allowing the door to open to a preset partial position.

Maintenance Features

Regular maintenance is crucial for the safe and reliable operation of your Merlin Commander Extreme MS125MYQ garage door opener:

Monthly Checks:
- Manually operate the door to check for balance and binding. If the door is unbalanced or binds, a qualified door technician should be called.
- Ensure the door opens and closes fully. Adjust limits and/or force if necessary.
- Repeat the safety reverse test monthly and make any necessary adjustments to ensure the door reverses on contact with a 40 mm obstacle.
Annual Checks:
- Lightly grease the chain and the inside of the rail assembly where the trolley slides. Use gloves to protect against sharp metal edges. The opener's internal components do not require additional lubrication.
Battery Replacement: The batteries in remote controls have a long life, but should be replaced if the transmission range decreases. Use identical or equivalent CR2032 type batteries and observe polarity. Dispose of old batteries properly at designated collection points.
Warning Labels: Permanently fasten the provided warning labels in prominent places: one near the fixed Wall Control (Risk of entrapment), one on the manual release cord (Emergency Release/Service label), and one on a low inside panel of the door (WARNING Child Entrapment). These serve as reminders of safe operating procedures.
Door Installation Examination: Frequently examine the door installation, paying particular attention to cables, springs, and mountings for signs of wear, damage, or imbalance. If repair or adjustment is needed, do not use the opener, as springs and hardware are under extreme tension and can cause serious personal injury.
Electrical Connection: Ensure the opener is connected to a properly fused and earthed 240 V General Purpose Outlet (GPO) in close proximity to the powerhead.
Obstruction Removal: Before operating the opener, ensure the door's path is clear of obstructions.
Professional Service: If the supply cord is damaged, it must be replaced by the manufacturer, its service agent, or similarly qualified persons to avoid hazards. For complex issues or diagnostic codes, contact a trained service specialist.
