Digital T&H sensors Indoor Temp. & Humidity Panel size: 72x72mm(square) 2 control relays RS485 modbus-RTU

1.General

WHD Series T&H Controller is mainly used to control the temperature and the humidity in the indoor area. It is equipped one or multi digital temperature and humidity sensor. It can display or loop display the data of T&H on its LED. And the same time, it can transmit the measured data by RS485  port and can control the fan or heater by its relay output. 

2.Characteristic

· With the Swiss digital T&H sensor, high accuracy and simple wiring;

· Each sensor corresponds to 2 control contacts to connect the fan and the heater;

· Programmed by keys on the front. The user can set the device parameter according to their need;

· the programming parameter can be stored when no power;

· With excellent Electronic Magnetic In EMI

· It is protected by password.
