Scope of application 
 HS401 temperature and humidity control is widely used in the 0.1-35KV indoor switchgear, such as: the counters in the home, the handcart cabinet, fixed cabinet, ring counter, low voltage cabinet and other switchgear. 
 Basic functions 
 HS401 with two control output contacts. Imported sensors, digital tube real-time display. Multi-channel display, the switch automatically cycle every 30 seconds, the user can arbitrarily set the temperature, humidity, upper and lower limits. When the temperature reaches a certain level or temperature sharp increase, it may happen condensation, the controller driver heater work; condensation status disappears, the heater stopped heating, the controller back to the monitoring state. When the heater is disconnected. The controller issued a disconnection alarm signal. 

 The main technical indicators 
 ◆ working environment: Temperature: -20 ℃ ~ 70 ℃ Humidity: ≤ 95% RH 
 ◆ Temperature: ≤ 5 ° C ± 0.5 ° C relay closure heating start-up; 
 ≥ 15 ° C ± 0.5 ° C relay reset heating exit; 
 ≥ 40 ° C ± 0.5 ° C when the relay is closed exhaust start; 
 ≤ 30 ° C ± 0.5 ° C relay reset exhaust exit. 
 ◆ Humidity: ≥ 90% RH ± 1% RH, the relay is closed heating start; 
 ≤ 75% RH ± 1% RH relay reset heating exit 
 ◆ Input voltage: AC220V ± 10% 
 ◆ Relay contact power: AC220V/5A, (normally open, passive)
