Line 1: temperature and humidity inside the thermostatic box (or area I);

Line 2: box air conditioner status, real time clock;

• ------- cooling start sign;

☼ ------- heating start sign;

♂ ------- hydrogen exhaust/direct ventilation sign;

-- ------- compressor/ heater stop working.

Interface 2:

Line 1: environment (or area II) temperature and humidity;

Line 2: inside and outside coil temperature display (T3, T4);

Interface 3:

Circularly display current alarms;

When multiple alarms occur, it will display each alarm information circularly.
