CONTROL SOLUTIONS  WTC Control architecture A variety of configurations for every application 42NM 42GW WTC WTC 42BJ WTC BACnet or LON SUB-Bus RS485 via RJ45 WTC Light Module Blind module Wired UI Wall mounted 42NL/42NH Up to 4 light circuits Up to 4 blinds Presence Ligh IR Remote UI Infra Red Features and advantages ■■ High efficiency: The WTC’s energy saving algorithms control fan speed and manage water operation in parallel achieving optimal energy consumption whilst ensuring there is no esulting loss in comfort for occupants. ■■ Easy installation: The WTC is comptable with the full Carrier fan coil range. For Customers and installers the same controller simplifies and eases installation and service operations whilst covering a wife range of hydronic system types and applications. The WTC is factory installed on the terminal fan coil before factory testing of each individual terminal. As result, field installation is extremely simple. ■■ Variety of configurations: The controller can operate as either a standlone control, command and follow function for open spaces, or at the heart of a building management system. ■■ User friendly user interface: The user interface is avallable in a variety of configurations: no display, LCD display, temprature sensor, lights and blind control, etc. Advanced functions ■■ Demand controller ventilation (DCV) & IAQ management: on fan coils equipped with CO2 sensors and fresh air dampers, the WTC can adjust the amout of fresh air admitted to the room, as required by the occupants. ■■ Lights and blind management modules: The WTC supervises the interconnection of light modules & blinds modules, allowing the user to improve local comfort control with the same user interface as HVAC system. CONTROLS ■■ Low Energy Consumption (LEC) variable speed control: The WTC can drive the fan speed continuously within a configurable range for optimal thermal and acoustic comfort. ■■ Modulating hydronic control: The WTC controls both floating and fixed-point value actuator types (230V on-off and 230V three point).
