Circuit
Function
Input/output
Central data transmission interface
Used by centralized control equipment for
operation control. Allows control of up to 64
groups of air conditioners and heat recovery
ventilation units. Use of KRP2A61 allows zone
link operation.
Remote control data transmission interface
Use of dedicated LCD remote controller allows
control of up to 16 heat recovery ventilation
units. Also used for linked operation of air
conditioners of 2 groups.
Air conditioner link operation
Connects to remote control line of air
conditioner for linked operation.
Output
KRP50-2 interface
Can be used to output signals of operating
condition and abnormalities to external
equipment or to connect humidifier via
KRP50-2.
Relay drive circuit
Supplies drive voltage to relay coils.
Fan motor, damper motor relay
Power supply relay for fan motor and damper
motor.
Input
Thermistor interface
Uses thermistor (temperature sensor) to detect
inside and outside temperatures.
Airflow rate setting switch interface
Used to set airflow rate of main unit when
dedicated remote controller is not used.
External input interface
Used to control main unit with external contact
point. (Freshup, external link operation, etc.)
Damper limit switch interface
Sends signal of limit switch condition to
microcomputer for damper motor cam
positioning.
Peripheral
Parts
Control microcomputer
Controls entire equipment by varying output
according to input condition.
EEPROM
Stores operating condition and address data.
Microcomputer Microcomputer reset circuit
Resets microcomputer when power is turned
on.
Microcomputer oscillation circuit
Generates clock frequency for microcomputer
operation.
Power Supply
Power transformer
Produces power supply of approx. 26 VAC
from 220-240 VAC.
Power supply circuit
Supplies direct currents (16 VDC, 5 VDC) to
control circuits.
