ALERTON Product Lines We Repair
Our engineers are trained on the full ALERTON product range. Below are the major product families we service.
Alerton Compass Controllers
Modular DDC controllers for HVAC and facility automation. Common issues include network communication loss, input/output module failures, and firmware corruption affecting building comfort control systems.
VAV Box Controllers
Variable air volume terminal unit controllers with local and networked variants. Frequent faults include sensor signal loss, actuator control drift, and communication timeouts in multi-zone installations.
Rooftop Unit Controllers
Standalone and networked RTU controllers for air handling and cooling management. Common repairs involve compressor control relays, temperature sensor failures, and BACnet gateway communication issues.
I/O Modules and Communicators
Analog and digital input/output expansion modules plus BACnet and LON communicators. Typical failures include relay coil burnout, analog signal conditioning errors, and network interface card degradation.
TouchPad Display Terminals
Local operator interfaces and graphics terminals for building system monitoring and manual override. Common defects include touchscreen responsiveness loss, display corruption, and serial/network port failures.
Network and Integration Modules
Ethernet bridges, BACnet/IP gateways, and protocol converters for multi-vendor system integration. Issues range from packet loss and DHCP conflicts to firmware incompatibilities in converged networks.

Common ALERTON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ALERTON equipment arriving at our workshop.
- ✓Alerton controller no network response, offline status — Ethernet interface failure, corrupted BACnet stack, or DHCP timeout in Compass and RTU controllers. Commonly caused by power surges, loose connectors, or firmware version conflicts in networked installations.
- ✓Analog input reads erratic or stuck values — Conditioning circuit failure in Alerton I/O modules, sensor signal ground loop, or ADC (analog-to-digital converter) chip degradation affecting HVAC feedback loops.
- ✓Relay coil burnout, no load switching — Overload, inductive spike damage, or aged relay contacts in Alerton output modules and controller boards. Common in compressor/fan contactor circuits under Indian power quality conditions.
- ✓VAV controller sensor signal loss, erratic airflow — Broken ductwork pressure taps, failed differential pressure transmitter, or sensor interface connector corrosion in Alerton VAV-3000/3100 controllers.
- ✓TouchPad display frozen, no response to input — Touchscreen controller chip failure, corrupted firmware, or serial/USB interface fault in Alerton operator panels impacting human-machine interaction.
- ✓BACnet communicator packet loss, slow responses — Corrupted BACnet stack software, Ethernet PHY chip failure, or protocol timing errors in Alerton BAC-3000 and network gateway modules during high-traffic periods.

Our test lab includes a full BACnet network simulator for validation. We reflash firmware, replace network interface cards, and perform multizone commissioning verification to ensure proper integration with your building automation backbone.
Do you offer calibration and testing certificates for repaired Alerton equipment?+
Yes. Every repaired Alerton device undergoes functional testing, sensor calibration (where applicable), and pressure/flow verification in our lab. We provide detailed test reports documenting input/output accuracy, response times, and sensor ranges. These certificates are accepted by most facility management teams and help demonstrate compliance with Indian energy auditing standards.
What is your warranty on Alerton repairs?+
Synchronics provides a 12-month parts and labour warranty on all Alerton repairs. If a repaired component fails within this period due to our work, we repair or replace it at no charge.
