Ningguo Kingcool Import and Export Co., Ltd is a China-based manufacturer and supplier of HVAC parts, combining metalized polypropylene film capacitor production with a broad air-conditioner and refrigeration parts catalog. Under the Universal A/C Control System & Remote range we supply universal control boards, multi-brand remote controls and remote signal testers for split and window air conditioners, serving HVAC technicians, parts distributors and maintenance teams that need one SKU to cover many OEM boards.
Our Position in Universal A/C Control
As a Air-Conditioner Parts-Universal A/C Control System & Remote Manufacturers, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.
We build and source universal control systems that replace failed OEM boards across a wide range of air-conditioner brands. The range is designed around fixed-frequency (on/off) compressors and the wiring conventions found in split and window units, so a single board can serve many repair situations instead of a brand-specific spare.
Because we also manufacture capacitors and act as an agent for air-conditioner and refrigerator accessories, our control products sit inside a one-stop parts supply: a technician or distributor can combine a universal board, a matching remote, a run capacitor and a temperature controller in one order. Each employee deals directly with the market, which lets us respond quickly to fragmented and personalized requirements.
Product Range and Application Fit
Three product types make up the category. Each has a distinct role in A/C repair, maintenance and distribution.
| Product | Key Features | Best For |
|---|---|---|
| Universal A/C Control System | 3 fan speeds, sleep function, auto-defrost, 5 working modes, auto-restart | Replacing failed OEM boards in split and window units |
| Universal Remote A/C Control KT-109 II | Large capacity, long range, LCD display, mode indicator, temperature range | Multi-brand remote replacement for residential and commercial use |
| Remote Signal Tester | Detects and diagnoses remote control signals | Technicians verifying remote functionality during service calls |
These products suit HVAC technicians, parts distributors and maintenance teams working across diverse A/C brands. Our universal boards simplify inventory by covering multiple models with one SKU, and the remote range reduces the number of handset variants a distributor must stock.
Engineering and Compatibility
Our universal control systems use relay-based switching to manage high-current compressor loads, supporting both rotary and reciprocating compressors. Boards carry adjustable fan speed taps (High, Medium, Low) to match various indoor blower motors, and we include our own thermistors (room and pipe sensors) to bypass proprietary resistance values so temperature control stays accurate.
- Multi-brand compatibility for split and window units
- Wide voltage range optimized for unstable grids
- Integrated 3-minute compressor delay protection
- Multi-code infrared database for remote control
- Standardized wiring for versatile installation
Critical Specifications and Performance
Our control boards are designed for fixed-frequency (on/off) compressors. They support 5 working modes (cool, heat, dry, fan, auto), 3 fan speeds, sleep function and auto-restart after power failure. Auto-restart is particularly valuable in regions with unstable power supply, as it resumes previous settings without manual intervention.
For remotes, the KT-109 II offers a long-range signal and a large LCD display. It uses auto-search logic to cycle through thousands of manufacturer protocols, allowing one remote to control virtually any brand. The remote signal tester helps technicians quickly verify whether a remote is transmitting correctly.
Installation and Integration
Installation is straightforward with standardized wiring. Each board comes with a wiring diagram and labeled terminals for compressor, fan and power connections. We recommend that installation be performed by a qualified technician. The boards are compatible with 110V/220V AC power supplies, and we can provide guidance for specific voltage requirements.
For automation integration, our systems can be paired with smart home controllers via IR blasters, but they are primarily designed as standalone replacements. We do not offer Wi-Fi built-in models in this category.
Quality Control and Testing
As a manufacturer with advanced testing equipment, we conduct rigorous quality checks on every control board and remote. Each unit is tested for functionality, signal strength and durability before shipment. Our factory follows a service-oriented business model, allowing us to quickly adapt to customer-specific requirements. We also provide technical documentation, including user manuals and wiring diagrams, with each order.
Information We Use to Configure Your Solution
To prepare an accurate quotation and ensure the right product fit, we use the following project details:
- Original A/C brand and model (if available)
- Compressor type (rotary, reciprocating, inverter)
- Voltage and frequency (e.g., 220V/50Hz)
- Indoor fan motor type (PSC, shaded pole, etc.)
- Required features (e.g., auto-restart, sleep mode)
- Quantity and packaging preferences
With this information, we can recommend the correct board or remote and confirm compatibility.
Maintenance and Support
Our control systems are designed for long service life with minimal maintenance. We recommend periodic cleaning of the remote sensor and ensuring the board is protected from moisture. Spare parts, including sensors and remotes, are available upon request. We offer technical support via email and WhatsApp, and we can provide training materials for installation teams. For bulk orders, we can arrange sample testing before mass production.

Our portfolio also includes Air-Conditioner Parts, Compressor and Capacitor for applications with different operating ranges, interfaces or integration requirements.
Frequently Asked Questions
Can a universal board support an inverter compressor?
Most standard universal boards are designed for fixed-frequency compressors. For inverter systems, we offer specialized kits. Please contact us with your compressor details to ensure correct selection.
How do the remote codes sync with different brands?
Our remotes feature auto-search logic that traverses thousands of manufacturer protocols. Simply point the remote at the A/C and press the set button until the unit responds.
What is the lead time for bulk orders?
Lead time depends on quantity and customization. Typically, stock items ship within 7-10 days, while custom orders may take 3-4 weeks. We confirm exact timelines with each quotation.
Do you provide OEM/ODM services?
Yes, we can customize branding and packaging for distributors. Minimum order quantities apply.
