Setting and Query
Set temperature and humidity set-point
When temperature set-point (P3) or humidity set-point (P9) has been set, the temperature and humidity control
parameters will be generated automatically and accordingly.
Keeping【Set】depressed for 2 seconds to enter into temperature and humidity set-point setting status.
Press【Enter】to switch between temperature setting status and humidity setting status:
SV window displays “***” + “tt”: temperature setting status.
SV window displays “***” + “HH”: humidity setting status.
Press【▲】or【▼】to set the set-point “***” (Keeping the key depressed can fast set).
Keeping【Enter】depressed for 2 seconds will exit setting status, the settings will be saved, and temperature and
humidity control parameters will be generated automatically and accordingly.
The setting status will exit without saving if there is no key operation for 15 seconds.
Temperature set-point : factory default setting for is 38℃, set range is 1 ~ 65℃.
Humidity set-point: factory default setting is 60%RH, set range is 10 ~ 80%RH.
Set temperature and humidity control parameters
Note: Setting these parameters will change the automatically generated values!
Press【Set】and【▲】simultaneously to enter into temperature and humidity control parameter setting status.
Press【Enter】to select parameter:
SV window displays the selection from “***” + “P0” to “***” + “PP”.
Press【▲】or【▼】to set the value of the parameter (Keeping the key depressed can fast set).
Keeping【Enter】depressed for 2 seconds will exit setting status, the settings will be saved.
