Note: Correct calibration is only possible · with valve · stroke > 1.5 mm The second or third attempt at calibration occurs automatically after an 8minute delay. After three failed calibration attempts the actuator stem remains in the extended position and the radiator valves are closed. For valves with strokes < 1.5 mm, the actuator/valve combination locks after three failed calibration attempts. The new Siemens type VDN.., VEN.. and VUN.. radiator valves have in all 1.5 mm stroke.
