1.- Summarize

BJ-S series Temperature and Humidity Controller is a measurement device used on

temperature and humidity control. and the humidity control module is integrated in the system,

greatly improving the suitability of the equipment, obtaining the temperature and humidity change

from the sensor and sending the measured data to the electronic processor. The output device will
then control the temperature variation within a specific range.

With high technological content, using load control relay output, has fast output response,

accurate PID parameter auto-tuning, support, Modbus communication protocol and is built-in with

various output types, allowing different systems to reach a stable control status very quickly, can

be used in the worst environment for long-term use, applied to the various occasion which need

temperature and humidity control.

It is the ideal product to protect the normal efficient operation of power equipment and to

reduce cost. And can be used in other place need of temperature and humidity control.

2.- Features

7.- Safety considerations

All installation specification described at the previous chapters named :

SPECIFICATIONS, INSTALLATION,

OPERATION MODES, and SETUP PROCEDURE

Note that with the controller powered on, the terminals could be dangerous to

touching and cover opening actions or elements removal may allow accessing

dangerous parts. This controller is factory-shipped at proper operation condition.

8.- Maintenance

The BJ-S series controller does not require any special maintenance. No adjustment,

maintenance or repairing action should be done when the instrument is open and powered on,

should those actions are essential, high-qualified operators must perform them.

Before any adjustment, replacement, maintenance or repairing operation is carried out, the
