Relation between H3DT Ambient Temperature and Mounting Interval (Reference Values)

The relation between the ambient temperature and mounting interval is shown in the following graph.
If the Timer is used at 55°C or higher with a mounting interval that is smaller than that shown in the following diagram, the temperature inside the Timer will increase, reducing the life expectancy of internal parts.
