Architecture: Seamless Integation with BMS

Unlike the commercially available thermostat that requires installation of network concentrator when integrating with the BMS (Building Management System) develop package; the TPD series can be integrated with the Building Management System directly via Modbus TCP protocol by Ethernet; therefore lower the complexity of system implementation and reduce the future maintenance/operation costs.

Introduction:

FCU (Fan Coil Unit) is widely used in commercial building for air conditioning system, with relay board and thermostat, it allows easy control for maintenance of comfortable indoor temperature. To maintain user-defined indoor temperature, the relay board is used for controlling the air flow of FCU, and the flow rate of the two-way valve or three-way valve for the chilled-water and hot-water in FCU. And the thermostat provides users interface for easy set-up of the temperature and air flow.

The ICP DAS SC series control module in FCU works not only as a relay board, it also provides functions such as: assigning network address, switches testing, delay of power output. And with the TPD series color TouchPAD (works as thermostat, preloaded with intelligent control procedures), in addition to temperature setting function, it can also perform various functions such as: schedule setting, temperature compensation, remote control, and remote schedule setting, etc. The users can experience a more visual upgrade interface with intelligent features that mechanical or monochrome LED HMI cannot achieve.

One to many Architecture to Quickly build a system

A TPD supports up to six SC series control modules, to set up how many SC series control modules to be connected to one loop, just adjust the rotary switch (2 to 7) on the back of the TPD (2 to 7 indicates connecting to 1 to 6 relay boards), and then set up the loop address (1, 2, 3, 4, 5, 6) on the front of each SC series control module to complete the settings.

 

No programming Required & Intuitive Interface

The TPD preloads 15 operation pages with full-range features. With the intuitive interfaces, no programming is required for users to set up operations such adjusting temperature or start/stop the FCU. In addition, the preloaded interfaces also make it easy for operations in schedule setting, temperature compensation and remote control, etc.
