Active load hole 67X67 intelligent temperature and humidity controller
Operating Manual (V1.11)
The temperature and humidity controller system uses high-reliability microprocessor
and high-performance digital temperature and humidity sensor, with intelligent software
control technology combination, the controller has strong anti-interference ability, high
control accuracy, flexible control mode, can meet different temperature and humidity
control needs.
The upper and lower limits of intelligent temperature and humidity, control return
difference and control mode are set respectively, which can effectively prevent all kinds of
accidents caused by high environmental temperature and humidity and condensation
production, and realize dehumidification, heating and anti-condensation control selfchemical. The temperature and humidity controller by the design institute of electric power
design department, power equipment manufacturers and the power supply company longterm application, with completely reliable, simple installation, maintenance free, long-term
stable operation, can be widely used in all kinds of power cabinet (high and low voltage
switch cabinet, box substation, ring network cabinet, operating mechanism box, etc.) of
supporting facilities, and various buildings, ships, storage and other temperature and
humidity control requirements.
