IHC-200: Switch the modes between humidification and dehumidification automatically. Features of ITC-308 Plug and play design, easy to use; Dual relay output, be able to connect with refrigeration and heating equipment at the same time; Support reading with Centigrade or Fahrenheit unit; Maximum output load: 1000W(110V)/2000W(220V); Dual display window, be able to display measured temperature and set temperature at the same time; Temperature calibration; Compreor delay protection for refrigeration control; High and low temperature alarms are available; Over-temperature and sensor fault alarm; Heating/Cooling differential function could be set separately for refrigeration and heating to protect temperature controller from violent change. Description of ITC-308 ITC-308 is an easy-to-use, safe and reliable dual relay output temperature controller. D esigned with compreor delay protection for refrigeration, high and low temperature alarm, and sensor fault alarm, which makes the ITC-308 more safe and reliable. Functions such as temperature calibration, separately set differential for refrigeration and heating, enable more accurate temperature control. With large output power 1,000W(110V) /2,000W(220V), its suitable for most applications. It can be used as Over-temperature protection and automatic temperature control system for various electric appliances such as equipment for home-brew, aquarium, pet breeding, incubation, BBQ, seedling heat mats, oven temperature control, terrestrial heat control, constant temperature cycle of heating pump, culture fermentation, accelerating germination, electric radiator, electric oven, etc. Specification: Temperature Control Mode :On/Off Control, Heating and Cooling Temperature Control Range : -50~99 C / -58~210 F Temperature Resolution: 0.1 C / 0.1 F Temperature Accuracy: 1C (-50 ~ 70C) / 1F (-50 ~ 160 F) Ambient Temperature: -30~ 75 C / -22~ 167 F Input Power: 100 ~240VAC, 50Hz/60Hz Temperature Control Output: Max. 10A, 100V ~240V AC Input Power Cable Length: 1.5m (5ft) Output Power Cable Length: 30cm (1ft) Buzzer Alarm: High and Low Temperature Alarm Sensor Type: NTC sensor (Including) Sensor Length: 2m / 6.56ft Relay Capacity: Cooling/ Heating (10A, 100-240VAC) Storage Temperature: -20~ 60 C / -4~ 140 F Storage Humidity: 20~85% (No Condensate) Dimension Body: 140x68x33mm (5.5x2.7x1.3inch) Warranty: 1Year Description of IHC-200 It is an easy-to-use, safe and reliable dual relay output humidity controller. Its play-n-plug designed: Plug it into wall socket, set your controllers humidification or dehumidification values to your need. It can maintain the humidity between humidification and dehumidification automatically. In addition, the humidifier and dehumidifier can be programmed separately, too. The maximum electrical load is 10A. It can fit many residential humidifier and dehumidifier. It is widely used for mushroom, mini greenhouse, ventilator fan, crawl space, turtle enclosure, curing chanmber, snake cage, tobacco cage and so on.
