ZL-7802D Humidity and Temperature Controller
Version 1.0b
Introduction
Optional PID and on/off temperature control.
Internal control resolution is 0.01℃ to reach better control
result.
Integrated SSR, with 5A rate power driving ability.
Optional external SSR-DA could drive heavier load.
With auxiliary outputs, the controller could control
incubator, climate room, warehouse, and so on.

Remark
E1
NTC sensor failure
E2
Humidity sensor failure
tHi
High temperature warning
tLo
Low temperature warning
HHi
High humidity warning
HLo

iA
External digital input alarming
At1
PID auto tuning fails (There is temperature interference during tuning)
At2
PID auto tuning fails (The amplitude of temperature oscillation is abnormal)
At3
PID auto tuning fails (The periods of temperature oscillation is abnormal)
At4
PID auto tuning fails (Time out)
SUc *
PID auto tuning success
UnL
Restore to factory settings
*. After auto tuned, display “SUc”, the controller does not control temperature now.
Press any key, the “SUc” disappears, start to PID control temperature.
