Air conditioning controller and air conditioning system

Abstract

An air conditioning controller according to an embodiment includes: a mechanical relay including a movable terminal, a stationary terminal, and a drive coil; a memory; and a processor. The air conditioning controller sends a control signal through the mechanical relay to an air conditioner. The processor performs boot processing for the air conditioning controller and energizes the drive coil to move the movable terminal to a predetermined position. The predetermined position is a position corresponding to transmission of a shutoff control signal for shutting off the air conditioner. At the boot processing, the processor does not move the movable terminal to the predetermined position if a switch avoidance condition is satisfied; otherwise, the processor moves the movable terminal to the predetermined position.
