Smart Curtain Control Module Selection Guide: Supported Motor Types
You have installed smart curtains but are confused about which control module to choose. It is frustrating to find out the module you bought is incompatible with your motor.
There are tubular motors, track‑drive curtain motors, blind motors and many other variants. How do you make the right choice? This guide covers all essentials for your straightforward selection.
1. What is a Smart Curtain Control Module
Simply put, it is the commander for curtain motors.
Traditional curtains require manual pulling while smart curtains support mobile phone or voice control. Traditional curtains need manual operation every day, while smart curtains can open and close automatically on schedule. Traditional curtains cannot link with other devices, while smart curtains can interact with lighting and security systems.
Available functions Mobile remote control Voice control Scheduled opening and closing Auto‑open at sunrise and auto‑close at sunset Lighting scene linkage
2. Main Types of Curtain Motors
Identify your motor type before selecting a control module.
Tubular Motor for Roller Shades and Rolling Gates
Mounting position: Built‑inside the roller tube Application scenarios: Roller shades, rolling gates, sun screens Voltage: 230V AC / 24V DC Control mode: Forward‑reverse rotation control for up stop down operations
Identification tip: This motor is used for upward‑rolling curtains.
Track‑Drive Curtain Motor for Side‑opening Curtains
Mounting position: Hidden inside the curtain track Application scenarios: Fabric curtains and sheer curtains Voltage: 230V AC / 24V DC Control mode: Forward‑reverse rotation control for open stop close operations
Identification tip: This motor is used for side‑pulling curtains.
Blind Motor for Slat Adjustment
Mounting position: Installed at the top of blinds Application scenarios: Aluminum blinds, wooden blinds, bamboo blinds Voltage: 230V AC / 24V DC Control mode: Forward‑reverse rotation plus limit position control
Identification tip: This motor adjusts light by rotating blind slats.
Sky Shade Motor for Roof Sun Protection
Mounting position: Built‑inside the roof structure Application scenarios: Sunrooms, atriums, skylights Voltage: 230V AC Control mode: Forward‑reverse rotation control
3. How to Select Control Modules
Select modules according to your motor specifications.
230V AC Motors Most Common for Household Use
| Model | Channel Count | Application Scenarios |
|---|---|---|
| MTN649808 | 8‑channel | Top household choice for whole‑house curtain management |
| MTN648704 | 4‑channel | Small apartments or individual zones |
Compatible motors 230V tubular motors 230V track‑drive curtain motors 230V blind motors Sky shade motors
24V DC Motors
| Model | Channel Count | Application Scenarios |
|---|---|---|
| MTN648704 | 4‑channel | Dedicated for 24V DC motors |
Compatible motors 24V tubular motors 24V track‑drive curtain motors Small‑size 24V blind motors
Advantages of 24V motors Safe low‑voltage suitable for humid environments such as bathrooms Low power consumption for energy saving Compatible with battery‑powered solutions

4. Key Selection Parameters
Voltage Matching
230V AC motors shall pair with MTN649808 or 230V‑version MTN648704 24V DC motors shall pair with 24V‑version MTN648704
Improper voltage setting will burn out the motor.
Channel Calculation
One channel controls one curtain unit. The total number of curtains equals the required channel quantity.
Calculation example Living room one sheer curtain plus one fabric curtain takes 2 channels Master bedroom one sheer curtain plus one fabric curtain takes 2 channels Second bedroom one fabric curtain takes 1 channel Study room one roller shade takes 1 channel
Total channels required are 6. Select an 8‑channel module for spare capacity.
Per‑Channel Power Rating
MTN649808 per‑channel maximum load 16A approximately 3500W MTN648704 per‑channel maximum load 10A approximately 2200W
Calculation formula Motor power multiplied by 1.2 starting current equals the required power margin.
5. Wiring Guidelines
5‑wire Connection for Blind Motors
Module terminal L connects to motor live wire Module terminal N connects to motor neutral wire Module terminal UP connects to motor upward rotation terminal Module terminal DN connects to motor downward rotation terminal Module terminal COM connects to motor common terminal
4‑wire Connection for Tubular Motors and Track‑drive Curtain Motors
Module terminal L connects to motor live wire Module terminal N connects to motor neutral wire Module terminal UP connects to motor open or upward terminal Module terminal DN connects to motor close or downward terminal
Wiring precautions Cut off power supply before wiring. Do not swap live wire and neutral wire. Set motor limit positions in advance. Complete function test before final fixing.
6. Frequently Asked Questions
Q How many curtains can one module control A It depends on channel quantity. An 8‑channel module supports eight independent curtain units.
Q Can blind motors and roller shade motors share one module A Yes, provided they operate under identical voltage either 230V AC or 24V DC.
Q Where shall the module be installed A Install inside curtain boxes or nearby ceiling access openings.
Q Can curtains operate after power failure A Most motors support manual emergency operation via pull cord or pull bead.
Q Is motor operating noise normal A Slight operating sound is normal. Excessive noise usually indicates incorrect limit position setup.
7. Whole‑house Matching Example
Living room sheer curtain plus fabric curtain with two track‑drive curtain motors takes 2 channels Master bedroom sheer curtain plus fabric curtain with two track‑drive curtain motors takes 2 channels Second bedroom fabric curtain with one track‑drive curtain motor takes 1 channel Study room roller shade with one tubular motor takes 1 channel Bathroom blind with one blind motor takes 1 channel
Total channel requirement 7 Recommended configuration MTN649808 8‑channel 230V AC with one spare channel.
Closing Notes
Three core principles for curtain module selection are correct motor voltage matching, sufficient channel count and reserved spare capacity.
MTN649808 8‑channel 230V AC is the preferred household model for whole‑house smart curtain systems.
