ir Technology Systems, Inc.

1.0 Introduction

1.1 General

Thank you for your selection of the CeilAiR® ceiling-

mounted air conditioning system made by Stulz Air

Technology Systems, Inc.

CeilAiR overhead air conditioning systems (OHS) are

designed and constructed using the ﬁ nest available

materials/components, state-of-the-art technology

and quality craftsmanship to provide years of trouble-

free service. Due to technological advancement, all

components are subject to change without notice.

All CeilAiR OHS systems and CyberAiR® centrifugal

condensers are designed to be installed indoors,

unless otherwise noted on the equipment. Propeller-

type condensers, condensing units, drycoolers and

pump packages are designed for outdoor use.

1.2 Product Description

CeilAiR OHS systems are designed to be the most

versatile and ﬂ exible ceiling-mounted air condition-

ing systems in the industry. The unit is available in

air-cooled, water-cooled, glycol-cooled and chilled-

water conﬁ gurations. The cooling capacity in BTU/Hr

will depend on the unit size, which can range from 1

to 10 tons, and can be either a single stage or dual

stage unit.

The functional modes of operation, in addition to

cooling, are heating, humidiﬁ cation, dehumidiﬁ cation

and ﬁ ltration, which provides complete environmental

control of a conditioned space. The cabinet

conﬁ guration is available in a 2’ x 4’ frame for units

ranging from 12,000 to 40,000 BTU/Hr (spot cooler

or ducted) or a larger frame for units ranging from

48,000 to 120,000 BTU/Hr (ducted only). For ducted

units, there are three basic conﬁ gurations of airﬂ ow

patterns: 90º/Right Angle, Straight-Thru and In/

Out Same-Face (reference Figure 3). Refer to the

installation drawing provided with your unit for the

type of cabinet conﬁ guration and for the layout

dimensions.

1.3 Controls

SATS offers a wide variety of control options for

CeilAir OHS series A/C systems. The controllers are

typically remotely mounted to a wall or control panel.

Your unit may be furnished with a Digital Thermostat

offered for basic control of Ceilair OHS systems. The

A-Tech 1.1 is utilized for single stage units and the A-

Tech 1.2 is utilized for dual stage units (see Section

3.3.2).

The advanced E² microprocessor controller is now

available for Ceilair OHS systems which provides

enhanced features for more comprehensive control

of the unit. These features include: full alarm system;

input/output monitoring status; full integrated control

of heating, cooling, humidiﬁ cation, and dehumidiﬁ ca-

tion; multi-unit control and remote communication

with building management systems.

If your unit is equipped with an E² controller, an operating manual is provided under separate cover. Refer to

that manual for detailed instructions on operating the system controller.
