SAFETY CONSIDERATIONS
GENERAL
The Fan Coil Controller is a field retrofit, low cost, CCN
(Carrier Comfort Network) control for fan coil units. The fan
coil controller is a microprocessor-based direct digital control
(DDC) controller for fan coil units. It can be retrofitted on
direct drive fan units manufactured by Carrier or other manu-
facturers to provide precise temperature control for applica-
tions of 2,000 cfm or less.
The fan coil controller can function as either a stand-alone
control or as part of the CCN. User interfaces include the CCN
Service Tool, ComfortVIEW™, and ComfortWORKS
®
soft-
ware. When used as part of the CCN, other devices such as the
CCN Data Transfer, Linkage Thermostat, or Comfort Control-
ler can read data from or write data to the fan coil controller.
SAFETY NOTE
Air-handling equipment will provide safe and reliable
service when operated within design specifications. The
equipment should be operated and serviced only by
authorized personnel who have a thorough knowledge
of system operation, safety devices and emergency
procedures.
Good judgement should be used in applying any manu-
facturer’s instructions to avoid injury to personnel or dam-
age to equipment and property.
Disconnect all power to the unit before performing mainte-
nance or service. Unit may automatically start if power is
not disconnected. Electrical shock and personal injury
could result.
If it is necessary to remove and dispose of mercury contac-
tors in electric heat section, follow all local, state, and fed-
eral laws regarding disposal of equipment containing
hazardous materials.
Damage to equipment may result. An individual field-
supplied 24-VAC power transformer is required for each
fan coil controller. The transformer must be less than
100 VA to meet UL Class 2.
