Overview
The BF-6812LC is a large-display refrigeration thermostat with a 148×102 mm front panel and an on-device parameter and help interface, so operators can read settings and guidance directly at the unit. It controls temperature from −50°C to 100°C at 0.1°C resolution on AC220V, and is aimed at larger cold storage and refrigeration systems where a clear, readable display and direct on-panel configuration save time during commissioning and daily operation.
The controller manages the full refrigeration cycle — compressor with start-up delay protection, periodic defrost, evaporator-fan control and alarms — and includes 1–100A current detection to protect the compressor. Its 5A/250V output can be customized for larger relays, which suits the bigger contactors and higher loads typical of industrial temperature control and large refrigeration installations.
Key functions
Large, readable display
A 148×102 mm panel with on-device parameter and help pages makes temperature control settings easy to read and adjust right at the equipment.
Full refrigeration & defrost control
Compressor delay protection, periodic defrost with dual time/temperature stop, drip-off and fan management keep large cold storage running reliably.
Current detection
Built-in 1–100A current detection protects the compressor against overload in demanding refrigeration duty.
Customizable output
The 5A/250V relay output can be customized for larger relays, matching the higher loads of industrial temperature control.
Where it's used
Large cold storage
In big cold rooms the BF-6812LC provides clear temperature control and defrost management, with a display large enough to check status across the plant room.
Large refrigeration systems
For higher-load refrigeration, the customizable output and current detection match larger compressors and contactors.
Industrial temperature control
On-panel configuration and a readable interface speed up setup and maintenance in industrial control environments.
Installation & use
Mount the controller in a 136×90 mm panel cut-out and wire it to an AC220V supply. Place the temperature sensor where it reflects the stored product temperature, and keep sensor and signal wiring clear of power lines to protect refrigeration control accuracy.
Fit the defrost sensor on the evaporator return pipe with waterproofing so defrost ends correctly. When driving larger contactors, size the output relay accordingly and add an independent high/low temperature alarm on critical cold storage.
Frequently asked questions
- What makes the BF-6812LC different?
- Its large 148×102 mm display and on-device parameter/help interface, plus a 5A/250V output that can be customized for larger relays — suited to bigger cold storage and refrigeration systems.
- What temperature range does it control?
- −50°C to 100°C at 0.1°C display resolution, with 1–100A current detection for compressor protection.
- Can it drive larger relays?
- Yes. The standard 5A/250V output can be customized for larger relays to match higher-load industrial refrigeration.
