Though the device shares power source, display, and key input with the controller, it has independent temperature measurement circuit,

CPU, sensor and output circuit. Overheating prevention temperature can be set using the operation panel.

The unit stops operation when the device is activated. The unit starts operation again when the POWER switch is pressed again (manual reset).

This calibration offset function is for calibrating the difference occurred between the required in- furnace temperature and control temperature

(sensor temperature) of the controller. This unit can be calibrated toward either plus side or minus side of the whole temperature range.

The temperature of overheating prevention device is automatically corrected when the temperature of controller is collected.

The unit starts operation with the same condition as just before power failure if it occurs during operation. Press the START/STOP key to start the unit again.

This function locks the established operation status.

It can be set and cancelled with the SUBMENU key.
