Control function

On/off: Controller is off, press

for 3 seconds, controller working. Controller is on, press

for 3 seconds, controller off.

Temperature control

1.

Main control(R1)+Auxiliary control(R2)

(T10 = 0)

a. Main temperature control work:

Measuring temperature ≤

Down limit temperature

T12, and main temperature control R1 stop time over

Main temperature control

(R1)mini stop time

T14, main control R1 working.

b Main temperature control off:

Measuring temperature ≥

Up limit temperature

T11, off main temp. Control R1.

c. Auxiliary temp. Control work:

Measuring temperature ≤

Auxiliary temp. Control(R2) start temperature

T13, and auxiliary control R2 stop time over

Auxiliary

temperature control (R2)mini stop time

T15, auxiliary control R2 working.

b Auxiliary temperature control off:

Measuring temperature ≥

Auxiliary temp. Control(R2) start temperature

T13 + 0.1 degree, auxiliary control R2 off.

2.

External SSR temp. Control up and down limit(T10=1)

Temperature node control mode.

Measuring temperature ≤

Down limit temperature

T12, and SSR temp. Control stop time over

SSR temperature control mini stop

time

T16

SSR is on.

Measuring temperature ≥

Up limit temperature

T11, SSR is off.

3.

External SSR PID temperature control(T10=2)

When external SSR main temperature control choose PID mode. Temp. Control will follow PID algorithm.

4.

PID procedure:(If with PID control, it is better to tuning the PID parameters, if the default the setting is not ideal.)

a. Be sure that the equipment inside temp. has been cooled to same to environment temp.

b.Press

and

simultaneously for 5 seconds to enter into tuning set mode. LCD display“Pid tun”,

c.Press

start external SSR, output power is locked,

is on. Controller start turning PID.

d.After PID turning finished,

is off.

e.When the heating temperature over 100

, controller will end this turning, and display “Pid E03” warning with fail turning(press any

key will cancel E03)

f.If self turning dont finished in 60 minutes, controller will display“Pid E04”warning with fail turning(press any key will cancel E04)

g.Press

can cancel warning E03/E04, and restart turning. During turning press

can exist.

Humidity control(R3)

Humidify control(H10 = 0)

When measuring humidity ≤

Down limit humidity setting

H21, and humidity load stop time over

Min humidity load stop time

H23,

humidify is on.
When measuring humidity ≥

Up limit humidity setting

H20, humidify is off.

Dehumidify control(H10 = 1)
When measuring humidity ≥

Up limit humidity setting

H20, and humidity load stop time over

Min humidity load stop time

H23,

dehumidify is on.
When measuring humidity ≤

Down limit humidity setting

H21, dehumidify is off.
