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).
