Safety Precautions

• Please read specification carefully before using the product.
• Do not touch the terminals at least while power is being supplied. This could lead to electric shock.
• Do not allow pieces of metal, wire clippings, or fine metallic shaving or filings from installation to enter the product. This can result in electric shock, fire, or malfunction
• Keep the product away from heat sources such as fires, flammable or explosive gas etc. This may lead to the generation of excessive heat, ignition and explosion
• Never disassemble, modify or repair the product or touch any of the internal parts. This can result in electric shock, fire, or malfunction.
• If the output relays are used over their life expectancy, contact fusing or burning may occasionally occur. Always consider the application conditions and use the output relays within their rated load and electrical life expectancy. Do not immerse product in water/ seawater

Introduction

What is IHC-200?
IHC-200is an easy-to-use, safe and reliable dual relay output humidity controller. Its play-n-plug designed, dual LED screens enabling more humanized. IHC-200 can control any 100-265 volt humidifier, dehumidifier or fan.

Main Features

• Switch the modes between humidification and dehumidification automatically;
• Control humidity by setting value and differential value;
• Calibrate the humidity value;
• Delay protection for control output;
• Query current humidity;
• Alarm when humidity exceeds high/low humidity setting value;
• Alarm when sensor error or humidity exceeds limit;

Specifications

Device layout and functions

PV: Process Value.

• Under running mode, display current humidity;

DECREASE key:

• Under running mode, press DECREASE key to inquiry DD value; Under setting mode, press DECREASE key to decrease value.

INCREASE key:

• Under running mode, press INCREASE key to inquiry HD value; Under setting mode, press INCREASE key to increase value

Humidification Device Socket: Humidification output

Dehumidification Device Socket: Dehumidification output

Basic Operation

Power On/Off

When the controller is working normally, press and hold "SET" key simultaneously for 3 seconds to enter the condition of power off, all the display and output would be turned off. On the condition of power off, press and hold "SET" key simultaneously for 1 second to enter the condition of normal measuring

Enquiry Differential Value

When the controller is working normally, short press " " key once, then the humidification differential (HD) will be displayed; Short press "" once, then the dehumidification differential (DD) will be displayed. Two seconds later, the display of humidity will be return to the normal display mode.

Enquiry Measuring Humidity

Press"" and "" key simultaneously to display the current humidity value on PV screen. Release the key for 2 seconds to return to the normal display mode

How to Set Parameters

When the controller is working normally, press and hold the "SET" button to set the parameters, the PV screen will display the first menu code"HS" and the SV screen will display the setting value.

Press "SET" key to page down the menu then the code would be displayed, presskey to change the current parameter values.

After finished settings, press and hold "SET" key for 3 seconds at any status to save the parameter setting value and return to the normal displaying mode of humidity. During setting, if there is no operation for 10 seconds, the system will quit the menu automatically and return to the mode of normal humidity displaying without saving the parameter's modification.

Setup Flow Chart

Settings

Humidity Control Range Setting (HS, HD, DD)

When controller works normally, LED displays current measured value of humidity, then starting the recognition and translation of humidifying and dehumidifying automatically.

When the measured humidity PVHS (Humidity Set Value) + DD (Dehumidification Differential Value), entering into the status of dehumidification, indicator lamp of dehumidification will on, relay of dehumidification will work. When the dehumidification indicator light is flickering, the dehumidifying equipment is being in the status of delay protection. When the measured humidity PVHS (Humidity Set Value), the dehumidification indicator lamp will off, and the dehumidification relay stops working

When the measured humidity PVHS (Humidity Set Value) - HD (Humidification Differential Value), entering into the status of humidification, indicator lamp of humidification will on, relay of humidification will work; When the measured humidity PVHS (Humidity Set Value), indicator lamp of humidification will off, the humidification relay stops working

Alarm High/Low Limit Setting (AH, AL)

When PV (the Measured Humidity Value) AH (Alarm High Humidity Set Value) or PV (the Measured Humidity Value)AL (Alarm Low Humidity Set Value), the alarm will make a beeping sound, the current value and AH/AL will display on the PV screen. Press any button will stop the alarm sound, but the alarm status will not change until the measured humidity value back to the set range.

Compressor Delay (PT)

When the controller is in dehumidification mode, it won't start dehumidification but will wait for a delay time if PV (the Measured Humidity Value) HS (Humidity Set Value) +DD (Dehumidification Differential Value).

When the time interval between two dehumidification operation (or the time from power on to dehumidify) is larger than preset delay, the equipment will start dehumidification immediately; when the time interval between two dehumidification (or the time from power on to dehumidify) is less than preset delay, the equipment won't start dehumidification until preset delay is satisfied.

Delay time will be calculated right after dehumidification stops working

Humidity Calibration (CA)

When there is deviation between measured humidity and actual humidity, use humidity calibration function to align the measured humidity and actual humidity. The corrected humidity is equal to humidity before calibration plus corrected value (corrected value could be positive value, 0 or negative value)

Error Description

Sensor fault alarm: when humidity sensor is in a short circuit or open loop, the controller will initiate the sensor fault mode, and cancel all the actions. The buzzer will alarm, LED displays ER. The buzzer alarm could be dismissed by pressing any key. After faults solved, the system will return to normal working mode.
