General Information
UniTrane fan-coil and Force-Flo units are intended for
single zone applications. These units have load
capabilities of 200 to 1200 cfm. See Figure 1 for unit
components. Fan-coil units are available as two-pipe, with
or without electric heat (one hydronic circuit) or four-pipe
(two hydronic circuits). Force-Flo units feature two-pipe
hydronic, electric heat only, or steam only. Also, these
units feature a variety of factory mounted piping packages.
Units with the three-speed fan switch only, are available
with the switch mounted on the unit, or shipped
separately, to be mounted in the occupied space. The unit
mounted three-speed switch option can be ordered with a
low voltage (24 vols AC) transformer and three fan speed
relays. The three-speed switch option, which ships
separately, comes with a low voltage (24 volt AC)
transformer.
The Tracer ZN010, ZN510, ZN520, and UC400 controllers
are included inside the units control box assembly. These
controllers utilize analog signals from a unit-mounted
control device or from a control device mounted in the
occupied space.
The controls interface option, includes a 24 volt AC
transformer, and an interface terminal board. Controls
provided by an external source can be tied into the
interface terminal board utilizing the integrated terminal
block with 3mm screw connections.
