Page 7 LOCK SETPOINT MODIFICATION The keypad can be locked by entering the “Basic Commands” menu using and pressing within 2 seconds, or by programming the “LOC” parameter (see “diS” folder). If the keypad is locked, the “Basic Commands” menu can be accessed and the Setpoint displayed, but the value cannot be modified.
Page 8 MOUNTING - DIMENSIONS The device is designed for panel mounting. Drill a 29x71 mm hole and insert the instrument; secure it with the special brackets provided. Do not install the instrument in damp and/or dirty places; in fact, it is suitable for use in places with ordinary or normal levels of pollution. Keep the area around the instrument cooling slots adequately ventilated.
