Fan Coil Zone Controller for Carrier Comfort Network® (CCN) System

  • California Prop 65


Product Integrated Controller

The Fan Coil Zone Controller is a field retrofit, CCN (Carrier Comfort Network) compatible communicating control for fan coils (specifically designed for applications under 2,000 cfm). Carrier's HVAC Controls fan coil zone 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® software. When used as part of the CCN, other devices such as the CCN data transfer, Linkage Thermostat, or Comfort Controller can read data from or write data to the fan coil zone controller.


  • Provides 3-speed PID (proportional integral derivative) automatic fan control to minimize fan noise by matching fan speed to load (also providing improved dehumidification during cooling and maximizing energy efficiency)
  • Uses PID heating and cooling control to maintain space temperature
  • Provides dehumidification control (requires RH sensor or RH value via network input)
  • Provides software clock and local occupancy schedule for local occupancy control (requires time broadcaster and hardware clock from another device in the system)
  • Provides a discrete input for use as a remote occupancy contact input or as a fan status input
  • Provides optional Linkage Thermostat interface capability
  • Features supply air temperature limiting and integrated safeties for DX (direct expansion) and electric heat units
  • Provides changeover control via a 10K ohm surface-mounted thermistor temperature sensor or via a forcible CCN software variable
  • Provides control of two-position outside air damper to maintain minimum quantity of outside air during occupied periods (after completion of warm-up)
  • Provides CCN Tables and Alarms
  • Provides diagnostic tests that enable the user to check I/O points and verify their functionality
  • Features spring return or non-spring modulating water valve capability
  • Provides optional remote-mounted space sensor with set point adjustment, timed override, and CCN service port jack
  • Controls modulating or two-position chilled water valves or up to two stages of DX cooling to maintain space temperature set point
  • Controls modulating or two-position hot water/steam valves or up to two stages of electric heat to maintain space temperature set point
  • Operates the supply fan based on a local or global occupancy schedule or remote timeclock input status
  • Provides Morning Warm-up or Smart Start cooling to achieve set point by the start of the scheduled occupied time (requires linkage thermostat or the use of the local occupancy schedule)
  • Provides alarms for analog temperature input(s) out of range
  • Provides alarm for space temperature deviation from desired set point
  • Provides Condensate Overflow alarm when condensate pan is full (optional)
  • Provides alarm for Dirty Filter based on resettable timer
  • Allows manual and system overrides of selected input/output channels
  • Supports CCN remote timed override, set point adjustment, and manual fan speed override
  • Provides Broadcast Acknowledger capability for CCN (configuration)
  • Conforms to the general requirements for CCN devices software
