INTRODUCTION
Description of Devices
The W7752D,E,F,G, and J Controllers and W7754K,L,M,N,
and P Controllers are Fan Coil Unit Controllers belonging to
the Excel 10 product line. Excel 10 FCU Controller systems
control the space temperature in a given room by regulating
the heating and/or cooling equipment which control the tem-
perature of the air delivered to that space and the fan which
controls air flow. Reheat coils are often included at the fan coil
unit. Excel 10 FCU Controllers are capable of stand-alone
operation; however, optimum functional benefits are achieved
when the network communication capabilities are used.
A family of direct wired wall modules with a temperature
sensor for space temperature measurement, setpoint adjust-
ment, bypass push-button, status LED, and LCD display can
be used in conjunction with Excel 10 FCU Controllers.
The wall modules are available in a variety of models
incorporating various combinatinos of the following options:
• Setpoint adjustment
• Bypass pushbutton and LED
• Fan Switching
• See Table 7 on page 12 for a complete list of wall
modules options
Excel 10 FCU Controllers connect to a LonWorks network and
interoperate with 3
rd
-party nodes.
