► Configuration and Function
Heater is composed of TEMP Sensor, Fan Motor, PTC Heater and Main PCB. The
description of these components is as follows:
1. TEMP Sensor
When the resistance value of TEMP Sensor changes according to the change of
the ambient temperature, NTC TERMISTOR (
10.0kΩ) of SENSING BULB detect the
change of temperature. The heater will be driven only when the detected temperature is
lower than the configured temperature.
(Turn on/off the heater through the relay of Main PCB)
2. Fan Motor
The fan emits the heat driven from the PTC heater.
3. PTC Heater
The PTC heater creates the heat by using AC power from Relay of Main PCB.
4. Main PCB
Main PCB is composed of AC Power circuit, LED Display and DC Power circuit
(No. 1 Pin : +24Vdc 0.2A for DC FAN, No. 2 Pin : GND)
