Introduction (Cont'd)
Communications
The QTC3 chiller comes standard with native communication capability for BACnet (MS/
TP), Modbus, and N2, with optional capabilities available for LON. The standard unit ca-
pabilities include built-in-scheduling, remote start-stop, remote water temperature reset
and up to two steps of demand (load) limiting depending on model. The standard control
panel can be directly connected to a building automated system via the standard factory-
installed RS232 communication port.
Serviceability
Minimal maintenance is required to keep the unit operating at maximum performance. If
service should ever be required, the QTC3 chiller has been designed to simplify the work,
keeping costs down. The layout of the chiller locates all the major components that can
be serviced near the outside edge. The condenser heat exchangers are light enough that
no crane is required for replacement. And when it’s time to clean them, city tap water,
with water pressure typical of a spray from a common garden hose, is all that’s needed.
