must be ON and operating to provide air flow through the heater (21-22-00).
Toggle the ENTRY HTR CONT switch to send a signal via the cabin data bus. This signal energizes
relay K1HR and sends power from the 115VAC 400Hz - CABIN BUS 2 bus to the heater. Circuit breaker
CBPG-38 provides circuit protection for the heater. An over-temperature sensor in the heater will turn the
system OFF in case of overheating.
