Product features
Precise Temperature Control & Multi‑Sensor Fusion
●Supports multiple temperature sensors (ambient, water inlet/outlet, coil, discharge, etc. – NTC/PT1000) and pressure sensors (high/low pressure protection) for real‑time system monitoring.
●Built‑in PID or fuzzy control algorithm for ±0.5°C precise water/room temperature regulation, preventing frequent start/stop.
●Automatically adjusts compressor frequency and electronic expansion valve opening based on return water temperature or indoor/outdoor temperature difference, improving COP (Coefficient of Performance).
01
Inverter/Fixed‑Speed Compressor & Fan Smart Drive
●Supports fixed‑speed compressors (relay/triac) or inverter compressors (BLDC/PMSM) with FOC (Field Oriented Control) sine‑wave drive – low noise, high efficiency.
●Fan supports multi‑speed or stepless adjustment, automatically adjusts speed based on condensation pressure or ambient temperature, adapting to different operating conditions.
I●ntegrated soft start reduces compressor inrush current and extends equipment life.
02
Intelligent Defrost & Four‑Way Valve Reversing Control
●Built‑in intelligent defrost logic: automatically enters/exits defrost mode (reverse‑cycle hot gas defrost) based on coil temperature, runtime, ambient humidity, etc.
●Four‑way valve reversing control for precise heating/cooling mode switching, with power‑off reset protection.
●Customizable defrost entry/exit temperature thresholds, maximum defrost time, forced defrost cycle, and other parameters.
03
Multiple Safety Protections & Fault Diagnosis
●Integrated high/low pressure protection, over‑current/over‑voltage/over‑temperature protection, discharge temperature protection, freeze protection, water flow switch or pump interlock protection.
●Compressor delay protection (3‑6 minute restart delay) to prevent short cycling damage.
●Fault self‑diagnosis: sensor open/short circuit, communication failure, compressor overload, etc. – indicated via LEDs or APP push notifications.
●Flame‑retardant PCBA (V‑0 rating), compliant with CE/FCC/UL safety standards.
04
Wireless Smart Interaction & Energy Management
●Optional RF, Bluetooth, or Wi‑Fi modules for remote control via remote controller, mobile APP, or smart speakers (Alexa, Google Home, Tmall Genie).
●Supports real‑time viewing of water inlet/outlet temperature, ambient temperature, operation mode, fault codes; remote on/off, temperature setting, heating/cooling/auto mode switching, timer on/off.
●Can be integrated into smart home ecosystems (Tuya, Matter, private cloud) for device‑to‑device automation with room temperature sensors, floor heating systems, and PV systems – optimizing energy saving strategies.
●Low standby power (<0.5W), supports weekly programmable scheduling and time‑of‑use electricity pricing modes.

Applicable scenarios
Residential Heat Pumps (Air‑Source Heating/Hot Water, Underfloor & Air Conditioner Combo Units)
Home users need efficient, quiet, stable heating/cooling and hot water solutions. Our Heat Pump Controller PCBA provides auto mode (adjusts compressor frequency based on indoor/outdoor temperature difference), supports water or room temperature control, and low‑noise operation at night. Users can remotely set temperature and monitor energy consumption via APP, and integrate with PV systems for self‑consumption. Factory direct supply, we can customize default temperature control curves and defrost strategies, and offer wholesale supply to home appliance brands.
Commercial Heat Pumps (Hotel Hot Water, School Heating, Agricultural Drying, Pool Constant Temperature)
Commercial scenarios require high power, continuous operation, and centralized management. Our controller supports high‑power inverter compressor drive, remote monitoring and fault alerts, optional RS485 or Wi‑Fi networking for unified management of multiple heat pump units by property management. Integrated freeze protection and low‑ambient heating optimization for severe cold regions. Customization supports integration with building management systems (BMS); factory provides wholesale PCBA and assists with CE/FCC/ETL certification.
OEM/ODM Manufacturers & Brand Owners
Providing core control solutions for global heat pump brands. Our standardized PCBA can be directly embedded into customer finished products, supporting rapid mass production. We also offer deep customization: compressor type (fixed‑speed/inverter), sensor brand/accuracy, defrost logic, electronic expansion valve drive method, wireless protocols, and PCB dimensions can all be adjusted as needed. As a source factory, we offer competitive wholesale pricing and stable lead times, and assist with product certifications (CE, FCC, RoHS, ETL, UL, etc.). OEM/ODM customers are welcome to contact us for customized samples.
