ZL-7901A Intelligent temperature and humidity controller

Instruction Manual A1.0

Feature

ZL-7901A is an industrial intelligent temperature and humidity controller. It can connect SSR expire output and adopt PID to

control temp with high precision. It use easy touched button and big LCD display, convenient operation and easy installation.
Applicable for control of incubator, climate chamber, warehouse, and so on.

Main function

1.Temperature control, three combination output, PID high precision control is chosen.
2.Humidify and dehumidify control
3.Time air exchange control
4.Time egg turning control
5.Illumination control
6.Node alarm output
7.Auto restart function
8.Temperature/humidity over limit warning and protection function
9.Temperature/humidity sensor fault warning and protection function
