General

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 I-GI-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 sepa- rately, to be mounted in the occupied space. The unit mounted three-speed

switch option, can be ordered with a low voltage(24 volts AC) transformer and three fan speed relays. The ship seperate three-speed switch option, only comes with a low voltage (24 volt AC) trans- former and three fan speed relays.

The Tracer ZN010, ZN510, and ZN520 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 1/4" female spade connectors.
