1.  Introduction:

KF-800D air quality controller is the latest model that can be used to

control heat recovery and with by-pass valve ventilator, users can choose

manual control or timing control for the operation of ventilator. Controller

output signal can directly control the startup and speed of ventilator. It can be widely

used in residential, commercial and industrial applications, and can effectively

improve air quality, create a healthy, comfortable, energy-efficient living and

working environment.

2.  Function & Feature:

1.  Real-time display indoor

temperature；

2.  Real-time display the current time；

3. Can

individually control anion, heating, defrosting, ultraviolet radiation

sterilization lamp, etc. inside ventilator.

4.  At night, it can be adjusted to

sleep mode by users.

5.  Timing mode ( 1- 9 period of time, can be set

different timing power on/off state)；

6.  Can control by-pass valve by manual, and can

used to control ventilator with or without heat exchange function.

7.  Working mode: Manual, automatic, timing；

8.  This air quality controller is practical and

cost-effective, operation is simple.

9.  Optional RS485 port
