[. . . ] Twisted-pair wire is recommended for wire runs longer than 100 ft (30. 5 m). NOTE: Maintain a mounting clearance of approx. (10 cm) to the left-hand side of the module in order to allow a free airflow for the temperature sensor and accessibility of the setpoint dial. Do not mount the wall modules on an outside wall, on a wall containing water pipes, or near air ducts. Avoid locations that are exposed to discharge air from registers or radiation from lights, appliances, or the sun.
