8.3 Setting Mode, Level 1
The method to enter to and return from setting mode Level 1 and which mode can be set in the level are
explained below.
8.3.1 How to enter and return
Press [SEL] key while power is turned on. Then, the indication on [MODE] is changed depending on the
number of press and the data in the indicated mode can be set. To return to current temperature
indication, press [RET] key.
When no input is done within 1 minute regardless of setting mode, the
current temperature indication is returned automatically.
8.3.2 Available mode in Level 1
The mode which can be set in setting mode Level 1 is as shown on Table 8-1. The mode available in
Level 1 is supposed to be used in normal operation including target temp. and offset.
The inputted data is written in EEPROM and memorized after the power
supply is turned off. The writing can be done up to 1 million times.
