850N / 3/4+ HPCS Power
The Synergy 370 delivers a maximum push/pull force of 850 Newtons, rated by Marantec as 3/4+ HPCS — Horse Power Comparable in Strength.
HPCS is Marantec's comparative lifting-strength rating and should not be interpreted as a conventional AC motor horsepower measurement.
The opener is designed to operate a properly balanced residential sectional garage door. It should never be used to compensate for broken springs, incorrect spring tension, binding tracks, damaged rollers, or an improperly balanced door.
Fast 9.3 in/sec Door Travel
One of the strongest advantages of the Synergy 370 is speed.
The operator is capable of door travel speeds up to approximately:
9.3 inches per second
This can provide noticeably faster opening and closing compared with many conventional residential garage door operators.
Actual speed depends on the door size, weight, balance, rail configuration, installation, and programming.
Quiet Belt-Drive Operation
The Synergy 370 is designed around a belt-drive system for smooth and quiet operation.
This makes it an excellent choice for:
-
Attached garages
-
Garages underneath bedrooms
-
Garages next to home offices
-
Homes where reduced vibration and operating noise are important
The DC motor also allows electronically controlled acceleration and deceleration for smoother door movement.
Soft Start / Soft Stop
The Synergy system gradually accelerates and decelerates the door near the beginning and end of travel.
This helps reduce abrupt movement and mechanical shock throughout the garage door system.
Reduced shock can help minimize unnecessary stress on components such as:
-
Rollers
-
Hinges
-
Door sections
-
Header attachment
-
Operator trolley
-
Door arm
-
Rail assembly
-
Counterbalance components
LCD Programming Display
The Synergy 370 incorporates an LCD display that guides the installer or user through the basic programming process.
The display simplifies setup and provides a more intuitive interface for programming travel limits and other operator functions compared with systems that rely entirely on combinations of indicator lights.
1,100 Lumens of Integrated LED Lighting
The Synergy 370 provides approximately 1,100 lumens of integrated LED garage lighting.
The LED lighting system offers strong illumination while consuming less energy and producing less heat than traditional incandescent garage-door-opener bulbs.
Marantec LED lighting is designed for long service life and is covered by a 5-year limited LED warranty, subject to Marantec's warranty terms and conditions.
Rotatable Motorhead
A useful installation feature of the Synergy 370 is the ability to rotate the motorhead to the right or left.
This can help accommodate:
-
Garage ceiling obstructions
-
Installation space constraints
-
Desired lighting direction
-
Specific garage layouts
The final installation configuration must still comply with Marantec installation requirements.
Multi-Function Wall Control
The included Marantec wall control station provides convenient garage-door operation from inside the garage.
The wall station is designed to fit over a standard junction-box location and can be combined with additional compatible Marantec wall control stations when required.
The system provides convenient access to operator and lighting controls from inside the garage.
Two 4-Channel Transmitters Included
This package includes two Marantec 4-Channel White Glossy Transmitters, part #122989.
The multi-channel design allows compatible Marantec devices or multiple garage-door operators to be controlled from one transmitter when properly programmed.
HomeLink Compatible
The Marantec Synergy 370 is HomeLink compatible.
Compatible vehicles equipped with HomeLink may be programmed to control the garage-door operator without requiring the handheld transmitter to be clipped to the vehicle visor.
Compatibility and programming procedures can vary according to vehicle manufacturer, model, and year.
Optional Timer-to-Close
The Synergy 370 supports an optional Timer-to-Close function when equipped and configured with the appropriate Marantec components.
Timer-to-Close can automatically close the garage door after a programmed period.
All required safety equipment must be correctly installed and functioning before automatic closing features are activated.
Optional Battery Backup
The Synergy 370 is compatible with Marantec's integrated battery-backup system.
Battery backup is NOT included with this Garage-DoorParts.com configuration.
A compatible Marantec battery-backup system can provide continued garage-door operation during an electrical outage when correctly installed.
🚫 California Sales Restriction
THIS CONFIGURATION IS NOT AVAILABLE FOR SALE OR SHIPMENT TO CALIFORNIA BECAUSE A BATTERY BACKUP SYSTEM IS NOT INCLUDED.
California law requires qualifying residential automatic garage-door openers sold, offered for sale, or installed in California to incorporate a battery-backup function capable of operating the opener during an electrical outage.
Customers requiring a Marantec Synergy 370 for installation in California must purchase a configuration that includes the appropriate compliant battery-backup system.

Installation & Safety
Garage door opener installation requires correct overhead mounting, rail positioning, door-arm geometry, electrical connection, photo-eye installation, travel-limit programming, force adjustment, and safety-reversal testing.
The garage door's spring counterbalance system must be properly functioning before the operator is installed.
⚠️ Garage doors and torsion or extension spring systems contain components under significant mechanical tension and can cause serious injury or death if improperly serviced.
Do not attempt to compensate for a damaged or improperly balanced garage door by increasing the operator's force settings.
Installation by a qualified garage-door professional is recommended.
