protection
Overtemperature protection is an option on the 301 controller. An independent control
circuit and temperature sensor provide the over temperature protection.
There are two reasons for overtemperature protection:
1. To prevent the material being used in a furnace or oven from over-heating.
2. To give an extra safety system to prevent the furnace or oven from heating in the event
of a fault.
