Room Unit of Communicating Fan Coil Thermostat
APPLICATION
HT961 communicating thermostats are designed for
application of 3-speed fan and valves in fan coil
system and available in BACnet MS/TP protocol.
HT961 Series thermostats can be easily integrated
into a building automation system based on the
BACnet MS/TP platform.
HT961 communicating thermostat adopts two-piece
solution consisting of two devices: driver and room unit.
Room unit provides user interface and control
algorithm for thermostats. This document contains
specification of HT9610P0200 room unit. For driver,
please refer to the data sheet of “HT961xD Series
Driver of Communicating Fan Coil Thermostat”.

Fan Operation
Fan can be selected as
manual or automatic 3speed operation. In
Manual mode, the fan is
switched to the selected
speed via control outputs
of the driver. While in
automatic mode, fan
speed depends on the
difference between room temperature and setpoint,
valve will be closed and meanwhile, fan will be closed
either.

FUNCTION
Valve Control
Room unit acquires the
room temperature via its
integrated sensor or
external temperature
sensor and maintains the
setpoint by delivering
on/off valve control
commands output.
The displayed temperature can be set to acquired
room temperature or setpoint. The setting can be
made during Installer Set-Up process.
Room temperature and setpoint can be display
simultaneously.
Cycle per Hour (CPH)
In order to get a more accurate temperature control,
CPH function may enable the thermostat to open the
valve for several times per hour even the temperature
is close to setpoint (difference less than ½ P-band).
The default value is 4 for heating and 3 for cooling and
can be changed in Installer Set-Up process.
