HVAC and building automation systems often stay in service long after the original controller, relay board, actuator or sensor has become hard to find.
Tekonline can help investigate replacement or compatible options for selected HVAC controls and automation parts, especially where the part number, photos and wiring details are available.
Parts we can investigate
- Damper actuators and zone control parts
- Relay boards, control modules and low-voltage interfaces
- Temperature, humidity and pressure sensors
- Obsolete HVAC controllers and compatible replacements
- ESP32, Home Assistant and custom control interfaces where appropriate
Useful details to send
- Part number, model number and brand
- Photos of the front label, wiring terminals and board
- Supply voltage and output type
- System type and what the part controls
- Any fault symptoms or technician notes
We will confirm whether a direct replacement, compatible substitute, repair path or custom interface is practical before quoting.
