Central system control with web functionality
The central system control GB-50ADA is ideally suited for both small and large systems since up to 50 air conditioning units can be operated with a single GB-50ADA. In addition, a maxi- mum of 40 central system controls can be combined into an integrated system in order to control and monitor up to 2,000 indoor units in large buildings. This way, a simple and central operation of complex systems is achieved.
All functions for the control and monitoring of all Mitsubishi Electric air conditioning unit models are included in the GB- 50ADA. To this end, external signals can be used and external units jointly operated (separate accessories required).
Power supply unit integrated
The integrated power supply unit does not only supply the sys- tem control, but can also supply the control lines of the M-NET data bus with the required operating voltage.
Web functionality
The GB-50ADA is not provided with an own display unit. Con- veniently control and monitor the air conditioning units by using
the standard web browser Microsoft Internet Explorer® (as of
version 5) on your PC, which is connected to your local network.
Highlights
• A GB-50ADA can control up to 50 indoor units or groups. • The compact system control is not equipped with a display
unit, the installation takes place „behind the scenes“. • Comfortably operate your air conditioning units on your PC –
thanks to the integrated web server functionality.
• The visually appealing user interface is easy to understand and you quickly learn how to use it.
• Clear symbols provide you with an at-a-glance overview of the unit status.
• Passwords protect the hacker-proof software that is not based on Windows but is a proprietary development of Mit- subishi Electric instead.
• Ideal for use in combination with TG-2000A.
Function Description
Display unit High-resolution colour touchscreen, screen diagonal of 9 inch, horizontal format (only for AG-150A)
Max. number of controllable indoor units Max. 50 indoor units / groups
Expansion options With up to three PAC-YG50ECA expansion modules for a maximum of 150 indoor units / groups (only for AG-150A)
On/Off On/off switching for each group separately or for all groups collectively
Operating modes Switching between cooling/dehumidifying/automatic mode/fan/heating, depending on the capabilities of the indoor units
Automatic mode only possible in R2/WR2 systems
Target room temperature Target room temperature for each group can be adjusted in the following ranges, depending on the capabilities of the indoor units:
• Cooling/dehumidifying: 19 – 30 °C • Heating: 17 – 28 °C • Automatic mode: 19 – 28 °C
Fan level Depending on the unit, up to 4 levels and automatic mode can be activated.
Airflow direction Airflow angle can be set to 4 stages and Auto Swing (depending on the unit)
Timer function Yearly or weekly timer. Night setback (12 °C) optional
Locking / releasing of local remote controls Locking and releasing of the individual remote control functions (On/Off, target temperature, operating mode and filter symbol Off) can be individually activated.
Display of actual room temperature The measured room temperature can be displayed for every group.
Fault messages Displayed as 4-digit error code and with the corresponding unit address. Up to 64 of the faults that occurred most recently are saved.
Test operation Enables the test operation for each individual unit within the group
Coupled operation with ventilation units Enables each group to engage in coupled operation with one Lossnay ventilation unit per group Limiting the temperatures in the browser The setting range can be individually limited for every single unit (e.g. 23 ºC to 25 ºC)
Web server functionality The central system controls AG-150A and GB-50ADA can also optionally be operated by using a standard web browser if the system control and the PC are connected to a local network. The administrator can set up, limit, block or allow the access of the users.
Automatic adjustment of the target temperature AG-150A and GB-50ADA change the target temperature depending on the outside temperature. This function is only available in cooling mode. To this end, a sensor input module PAC-YG63MCA and a PT100 sensor are required (PT100 sensor not included in scope of delivery)
Load shedding circuit Activates the energy-saving functions if the current consumption is too high.
Energy-saving functions Various energy saving functions (optional) for indoor units, groups or the complete system can be activated.
Optimised start of operation Already before the programmed timer setting is reached, the air conditioning system is started with a partial load that is slowly increased until the actual start of operation in order to then achieve the target state. This helps to save energy.
To this end, a sensor input module PAC-YG63MCA and a PT100 sensor are required (PT100 sensor not included in scope of delivery).
Password protection Access to the AG-150A and GB-50ADA can be protected by a password. If the background lighting of the LCD monitor goes out, the user will be prompted
to enter the password the next time he/she tries to gain access.
Night setback The capacity can be lowered if the rooms are not used or during the night hours. The system keeps the temperature in the rooms constant, e.g. in
heating operation at 16 – 19 °C, and thus prevents the rooms from cooling down. In daily operation, the system heats the rooms back up to 20 – 22 °C (only for AG-150A).
External inputs and outputs Connection terminals available for Inputs: On/Off via continuous signal, EMERGENCY STOP via continuous signal
Outputs: Operating status (On / Off), fault message / error-free operation
Refrigerant volume check Activates the automatic volume check function of the outdoor units for a simplified maintenance
