Danfoss TA (M28) thermostatic radiator sensor (operator head), liquid-charged, built-in sensor, 8–21 °C setting range, for M28 TA valves (013G2770)

Danfoss TA (M28) thermostatic radiator sensor, OEM order code 013G2770 — a self-acting thermostatic operator (sensor head): the liquid-charged sensing element expands and contracts with room temperature and drives the valve cone through the head, throttling flow to hold the set room temperature with no external power. It clamps onto M28 TA-connection radiator valves via the M28 TA connection (metal nut fixing) and requires no wiring or batteries. Temperature setting range 8 °C to 21 °C; sensing charge liquid; housing colour White RAL 9016. The head provides built-in frost protection (holds a minimum ~8 °C when turned to the snowflake position), adjustable maximum/minimum temperature limitation and set-point locking with hidden pins under the dial. Genuine Danfoss part; technical data quoted verbatim from store.danfoss.com (code 013G2770). OEM P/N 013G2770, EAN 5702420032320. HS 9032.10 (thermostats). Modulates refrigerant flow to the evaporator in response to superheat at the evaporator outlet.

Compatibility

Thermostatic operator head for M28 TA-connection radiator valves (M28 TA valve connection). Built-in type — the sensor reads the air at the valve; do not box in or cover the head, and mount horizontal pipework valves so the head is not above the radiator. Confirm the valve family (M28 TA) and sensor connection (Metal nut) before ordering; the head fits Danfoss M28 TA valve bodies only. No power supply required (self-acting). Setting range 8 °C–21 °C.
