ZL-7850R Temperature and Humidity Controller

Version 1.1

Feature

Another timer outputs R4 and R5 could drive such as incubator egg tray.
RS485 communication.

Function

Besides the function introduced in Feature:
Heating / Cooling mode option. Humidifying / de-humidifying mode option. R4 and R5 could be energized by keys, suitable for control the egg tray to any angle. Hight / low temperature / humidity alarm. Sensor failure alarm and outputs protection. Running status saving for power supply failure. Calibration for temperature and humidity. Temperature and humidity output delay protection.

Operation

On/Off

Keep key
〖 〗
depressed for 2 seconds to switch the controller between online and offline.
When in offline status, display “OF “.

Set temperature and humidity

Factory default setting: temperature is 37.8℃, humidity is 60%RH. Press key〖S〗to enter into/exit temperature and humidity setting status. At the setting status, display shows “set-value TP” or “set-value HP”.
Press〖 〗to switch between temperature setting (TP) and humidity setting (HP). Press〖▲〗or〖▼〗to set the value. Keep depressed could fast set. Keep〖S〗for 2 seconds to save the settings and exit the setting status. The setting status will exit without saving the settings if there is no key operation for 15 seconds.

Control

Multifunction Output R1

Over hot / wet protection: If R1 drives an exhaustion fan, it has the function to cool down or dry quickly.
Ref. to

Temperature control

-> Over hot protection, and
Humidity control
-> Over wet protection.
Timer output: R1 will be energized for【u4】after de-energized for【u3】, periodically.
Temperature control

Heat mode 【t0 = H】

If Room temp. ≤ Set temp. (TP) –【t1】, and Temp. Output (R3) has stopped for【t2】, then Temp. Output will be energized. If Room temp. ≥ Set temp., then Temp. Output will be de-energized.
