general information

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.

Model Number

Each UniTrane fan-coil and Force-Flo cabinet heater has a multiple character model number unique to that particular unit. To determine a unit’s specific options, reference the model number on the unit nameplate on the fan scroll. The unit nameplate also identifies the serial number, sales order number, and installation and operating specifications.

Following is a complete description of the fan-coil model number. Each digit in the model number has a corresponding code that identifies specific unit options.
