Abstract

Problem: When multi-zone heater is used, each zone has TC respectively. In other words, if there are five zones, five TCs are used. These will increase the cost and interfere with each other. Some patent publications disclose that a central control TC monitors the temperature of the central zone, and the power applied to the central zone (which is based on the feedback of the central control TC) is then applied to all zones as adjusted by the pre-established ratios. In this case, if the central control TC is out of the order, it will not be possible to control temperature.

Solution: Multiple TCs are installed in the central zone. If one TC is out of the order, a disconnection detection circuit will switch to use another TC, which functions as backup.

Some patent publications disclose that a central control TC monitors the temperature of the central zone, and the power applied to the central zone (which is based on the feedback of the central control TC) is then applied to all zones as adjusted by the pre-established ratios. In this case, if the central control TC is out of the order, it will not be possible to control temperature.
