The High Temperature limit dial is used to set the maximum temperature that the unit will work at. When the High Temperature limit sensor detects a temperature higher than what is selected on the EUR-5A high temperature dial it overrides the system and shuts it off. This function can be used to further regulate slab temperatures in pavement applications and as a warm weather override when the system is used for roof and gutter melting applications.
High Temperature Limit
Sets maximum temperature from 40°F to 90°F (4°C to 32°C).When that temperature is reached, the heat will always be turned off.
