Do not mount in niches, book shelves, behind cabinets or curtains, or where it could be exposed to solar radiation. Seal the conduit opening to avoid false temperature measurement due to draft from the conduit. The offset due to wire resistance per 10 m of distance from the sensor to the controller is stated in the following table: type of wire 0. 5 mm2 (AWG20) 1. 0 mm2 (AWG17) 1. 5 mm2 (AWG15) temperature offset PT100 BALCO 500 1. 8 °C 0. 3 °C (3. 24 °F) (0. 54 °F) 0. 9 °C 0. 15 °C (1. 62 °F) (0. 27 °F) 0. 6 °C 0. 1 °C (1. 08 °F) (0. 1 °F) NOTE: Use shielded wiring in areas with high EMI. Keep 15 cm (5. 9'') minimum distance between sensor lines and 230 Vac power lines. [. . . ] Printed in Germany EN0B-0240GE51 R1009 107 (4. 21") 60 (2. 36") 60 (2. 36") [. . . ]
