TFHB24F3XYZ2-EBA-140113.docx

Model

TFHB24F3XYZ2

with Humidity Sensor and BACnet Communication

Description

The TFHB24F3XYZ2 is a fully configurable controller designed

specifically for 2 pipe and 4 pipe fan coil applications. No

additional modules are required as the required inputs, outputs

and control algorithms are built into the unit. The

TFHB24F3XYZ2 also provides support for networked

communications via the BACnet MS/TP protocol. The

TFHB24F3XYZ2 also provides an internal humidity sensor to

dehumidify the controlled space when the humidity is too high

by cooling with the fan on low to create condensate.

TFHB24F3XYZ2

Applications

• Heating, cooling and reheat

• 2 pipes or 4 pipes

• Auxiliary heating sources, such as electric baseboards, can

also be applied

Features

• Backlit LCD with simple icon and text driven menus

• Configurable inputs and outputs

• 2 Pipes with Analog, ON/OFF, or Floating option

• 4 Pipes with Analog, ON/OFF, or Pulse option

• Internal humidity sensor and dehumidification sequence

(compensated by auto activation of reheat output)

• Precise temperature control with programmable PI function

• Selectable Fahrenheit or Celsius scale

• Independent cool and heat setpoint for No Occupancy

• Lockable setpoint, control mode, and fan mode

• Selectable internal or external temperature sensor

• Changeover by contact or external temperature sensor

• Selectable proportional control band and dead band

• Anti-freeze protection

• BACnet® MS/TP @ 9600, 19200, 38400, or 76800 bps

o Selectable MAC address

o Automatic or manual device instance assignment

o Automatic baud rate detection

o Copy and broadcast configuration to other

networked TFHB24F3XYZ2 modules

Typical Application

Fan coil applications provide heating and cooling to a zone by

circulating hot and cold air depending on the demand to maintain

an optimum temperature in the selected space. A fan coil setup

typically consists of fan coil units, source for hot and cold water,

and a pipe system for distribution. When there is a demand for

heating, the hot water is supplied to the unit through the source

and passes over the heating coil, and the hot air is pushed into

the zone by the fan. When there is a demand for cooling, the cold

water is supplied to the unit through the source and passes over

the cooling coil, and the cold air is pushed into the zone by the

fan.
