Product Description
Danfoss RA 2940 — self-acting thermostatic radiator sensor (control head) for Danfoss RA, RA-N and RA 2000 radiator valve bodies, OEM order code 013G2940. The RA 2940 is a gas-charged operator that modulates the radiator valve in proportion to room air temperature, holding a set room temperature without any external power or wiring; the gas charge gives a fast sensor response. The temperature-sensing element is built into the setpoint dial, sensing the air immediately around the valve. Setpoint range 5 °C - 26 °C, with a frost-protection setting and provision for maximum/minimum limiting and locking of the set-point. Mounts to the valve for Danfoss RA / RA-N bodies. Genuine Danfoss part; specification quoted from store.danfoss.com (code 013G2940). OEM P/N 013G2940, EAN 5702420048185. HS 9032.10.
