W1209 thermostat controller with probe

These details belong to the SKU and are shared by its batches.

Standalone W1209 temperature-triggered relay controller board with attached two-wire metal-sheathed temperature probe. Intended to switch a heater or fan around an adjustable temperature setpoint; no computer or external microcontroller required. Observed: three-digit seven-segment display, SET/+/- buttons, relay indicator LED, and four screw terminals labeled K0, K1, +12V, GND. Board uses 12 V DC power; K0/K1 are relay switch contacts, not a power output. Rear board marking W1209. Fitted relay marked SONGLE SRA-12VDC-AL; its printed contact ratings are not a verified safe load rating for the complete PCB/terminals. Exact maker, firmware, temperature accuracy/range and board switching-current limits unverified. Use an enclosed, appropriately rated low-voltage setup; this bare board is not established as mains-safe.
