V. Operation of the temperature controller
1. Look over and set parameter
(1)Look over parameter. Under the state of non-setting, pressing key ▲ show setting
value of temperature. Pressing key ▼ display the different between the present
temperature and temperature located, 2 seconds later, the screen will show the
present temperature.

(2)Set parameter
* method of entering into the state of customer setting: under not-setting state. Press
“SET' key longer than 5 seconds to enter customer state of setting up, setting
indicator to be on and to show the temperature at present.
* method of temperature setting :under the state of customer setting , press ▲
upwards or ▼downwards to adjust the temperature .Press one time to adjust 1
degree. It will be changed into rapid adjusting after pressing on it over 2 seconds.
*The method of exit from the state of customer setting Press SET key 5 seconds or
no any operation within 30 second under state of customer setting, system will store
