Microtech® 4 (MT4) is capable of controlling single or dual-circuit air/water-cooled liquid chillers. Microtech® 4 stages compressors necessary to maintain the desired heat exchanger leaving water temperature. In each unit mode it controls the operation of the condensers to maintain the proper condensation process in each circuit. Safety devices are constantly monitored by Microtech® 4 to ensure their safe operation. Microtech® 4 also gives access to a Test routine covering all inputs and outputs.
All the new Daikin air/water-cooled liquid Daikin chillers are already equipped with Microtech® 4. The existing models will get an upgrade from MT3 to MT4 in order to take advantage from the main benefits and improvement of the new control system.
The communication protocols available within MT4 Controllers are the following:
-Modbus RTU (Option 180)
-BACNet MSTP (Option 181)
-BACNet IP (Option 182)
The standard communication protocols are directly available within MT4 controller without any additional hardware to be installed. This will lower commissioning costs and speed up BMS integration.
As a standard, MT4 is ready to be connected through DoS with a LAN or a M2M data connection (Option 155).
