Haier Wi-Fi module MRV systems

Now you can use the new WiFi module to control all units in real time from your smartphone. Being the company with the largest market share in smart/connected air conditioners for 2 years in a row, Haier brings one more in a series of smart solutions and complements the already standard individual WiFi module for individual and multiple split systems (RAC and LCAC). MRV Haier Wi-Fi module HI-WA164DB The Haier Wi-Fi module enables simple and convenient control of connected indoor units through an application installed on a smartphone or a tablet with an iOS or Android operating system. The module needs to be connected to the local WiFi network which it uses to log in to the server and uses the Cloud system for remote network management of the units in real time. Assigning a module to an application is very easy and you just need to follow the instructions in the application. Application: Companies Supermarkets Small and medium hotels Bank branch offices, etc. Function controls On/Off function, temperature setting, timer settings, weekly programming, fan speed Overview of alarms, error history Division of function controls authority: local, central, blocking of the local handler User account management (account registration, password change through the application) One Wi-Fi module can control up to 64 indoor units and a combination of Wi-Fi modules, then 256 indoor units in the app under one user account. The application enables full individual and group control. Allows you to set user rights or user control options (levels). Connecting the MRV5 system MRV5 outdoor units have the standard equipment with a communication converter or Modbus RS485 output. Therefore, it is possible to connect the Wi-Fi module directly to the ports of the outdoor unit, and all the ports of the indoor unit will then be uploaded into the application. Connection of MRV-S and MRV-C systems To connect these systems, it is necessary to install the communication converter HA-MA164AD to which the Wi-Fi module will be connected. Connection of single-split, multi-split systems or combinations with MRV The Haier Wi-Fi module enables connection to the central controller HC-SA164DBT, which has an output for function controls via the Modbus RS485 protocol. If the central controller HC-SA164DBT is used, the Wi-Fi module can be connected directly to the central unit. The Wi-Fi module can be connected directly to MRV Series 5 outdoor units or to the HA-MA164AD inverter if the outdoor units are NOT Series 5. With this configuration, it is possible to manage the MRV system even without a local central controller, using only an application installed on a tablet or smartphone, and this ensures stable and fast Wi-Fi coverage of the module.
