CH53 code is a function detecting abnormal communication between the indoor unit and the outdoor unit of an inverter air-conditioner. If it occurs right after the product is installed, then ask the installation technician to check if the communication cables are wired properly with no misconnectio...
The ESL part of the MMR circuits feature a uniform logic realization comprising an inverter and a two-input AND gate with respect to each primary output of the function block. The internal outputs of the MMRESL (for example, MMRESLO1 and MMRESLO2, as shown in Figure 8) can be combined ...
