Enhanced Packages
Enhanced valve and piping packages add a strainer to the
Basic package supply water pipe. The strainer is attached to
the supply water pipe at the coil connections. The strainer
body is cast brass construction with a stainless steel mesh that
is easy to remove for cleaning.

(See Figure 10 for components key)
Premium Packages
Premium valve and piping packages replace the Basic
package a ball valve in the return line with a manual or
automatic circuit setter. The manual circuit setter is also
known as a manual ow control valve. The auto circuit setter
acts as both a ow setting device and a shut-off valve. It
allows water ow through the fan coil to be set quickly and
accurately. The circuit setter includes a cartridge within the
valve body that is sized to allow a specic ow rate through
the coil without any action required by a system piping
balancer.
P/T ports are included, which are used to measure the
temperature or pressure drop across the valve. This pressure
drop can be compared to factory supplied tables that relate the
pressure drop to a specic ow rate. The manual circuit setter
valve also has a memory stop so that the correct setting can
be found quickly.

Deluxe Packages
Deluxe valve and piping packages add a strainer to the
Premium package. The strainer is available with or without an
optional draining (blow-off) valve.

Manual Shutoff Ball Valve: Water shut-off.
Handle rotates 90 degrees.
Manual Shutoff Ball Valve with Memory
Stop: Used on return line for limiting water
ow.
2-Way, N.C., On/Off Valve, Spring Return:
Turn On or Off water ow to the coil in
response to 24V or line voltage signal
3-Way, N.C., On/Off Valve, Spring
Return: Bypass water ow away from coil
in response to 24V or line voltage signal.
Includes xed orice for balancing.
2-Way Modulating Valve (3-wire or
proportional): Modulates water ow in
response to 24V signal.
3-Way Modulating Valve (3-wire or pro-
portional): Modulates or bypass water ow
in response to 24V signal. Includes xed
orice for balancing.
PT Port: For connecting a pressure or
temperature gauge.
Y-Strainer: Removable screen lters out
small particles from supply line during nor-
mal system operation.
Manually Adjustable Circuit Setter with
Shutoff: Pressure-dependent, ball-type,
manual ow control.
Cartridge-Type, Auto-Fixed Circuit Setter:
Pressure-compensated, automatic xed-ow
control.
Union: For easy removal of piping from coil.
Bypass Balancing Valve: Adjustable
balancing of water ow through the bypass
circuit on a 3-way control valve.
Note: Daikin 3-way valves are equipped with a fixed balance orifice in the bypass
line, eliminating the need for a separate balancing valve
