The TC06-50ZEH/01 air conditioner is a full automation temperature control product. It uses intelligent

controller to control the whole system of the air conditioner. According to the variation of environment

temperature, the intelligent controller can automatically detect, operate and record the whole system’s

operating time, power consumption, event and historical data. It can store 100 event records and 1280

historical data records, and can enquire 256 days’ daily record information. The product is widely applied

in telecom cabinet, small and medium sized telecom room, UPS room, outdoor base station room, etc.

6.1 Application

ET872 controller is a type of universal intelligent controller. It is controlled by highly integrated STC single

chip microcomputer. It can intelligently control operating and hydrogen exhaust of thermostatic cabinet air

conditioner, and can control a telecom room air conditioner. It have the following functions: fault self

diagnosis, power on self start, restart after unexpected failures caused by other reasons.
 

The controller features perfect performance, easy and fast installation and setting, which is widely used in

telecom cabinet, small and medium sized telecom room, UPS room, outdoor base station room, bank ATM

banknote exchange room etc.
