Abstract:
Disclosed is a temperature control apparatus for a heater using an encoder switch and method thereof that controls an indoor temperature by driving a burner in accordance with a change of an indoor temperature and ventilating heated air indoors. The temperature control apparatus includes an encoder switch converting a user's set temperature value into a digital signal of a predetermined number of bits, a microcomputer for comparing the indoor temperature inputted in real time with the digital set temperature, driving the burner if the indoor temperature is lower than the set temperature by less than a predetermined temperature T1, and stopping the driving of the burner if the indoor temperature is high than the set temperature by more than a predetermined temperature T2, and a display unit for checking and displaying various kinds of error modes occurring while the burner is driven in accordance with a control signal inputted from the microcomputer.
Abstract:
A structure of a battery disconnection unit for an electric vehicle comprises a first high voltage relay switching to a position for supplying DC power supplied from the battery to the inverter or to a position for interrupting the supply of the corresponding DC power; a second high voltage relay switching to a position for supplying DC power supplied from the charger to the battery or to a position for interrupting the supply of the corresponding DC power; a PCB including a printed wired circuit electrically connected to the second high voltage relay and providing a DC power supply path between the charger and the battery; a substrate installed to support the first and second high voltage relays; and a metal bracket supporting the PCB and the substrate and operating as a heat sink radiating heat.
