3.1 General information

The Water Terminal Controller (WTC) is a
micro-processor based controller designed to
control and optimise the operation of
terminal fan coil units. The controller is
factory-installed on the terminal fan coil.
Depending on control functionalities, four
types of WTC hardware are distinguished:
WTC-207-L (LON), WTC-307-L (LON),
WTC-207-B (BACnet), and WTC-307-B
(BACnet).
These controllers are all built on a similar
platform, but have different numbers of
inputs and outputs as well as various digital
and/or analogue outputs (see also WTC
service guide). WTC is compatible with
WTC lighting / blinds expansion modules
(see also WTC-LEX/-BEX documentation).
Use the self-adhesive label available on
the controller to easily identify your WTC
device. Stick the label on the floor map!
