Low Ambient - An integrated low-ambient control

allows all units to operate in the cooling mode down

to 0ºF outdoor ambient without additional assis-

tance. Optionally, the control board can be pro-

grammed to lockout the compressors when the

outdoor air temperature is low or when free cooling

is available.

FEATURES

All models are available with a wide variety of factory-

mounted options such as stainless steel heat exchangers,

phase monitor, dirty filter switch, and coil guard to make them

suitable for almost every application.

All units are self-contained and assembled on full perimeter

base rails with holes in the four corners for overhead rigging.

Every unit is completely piped, wired, charged and tested at

the factory to simplify the field installation and to provide

years of dependable operation.

Anti-Short Cycle Protection - To aid compressor

life, an anti-short cycle delay is incorporated into the

standard controls. Compressor reliability is further

ensured by programmable minimum run times. For

testing, the anti short cycle delay can be temporarily

overridden with the push of a button.

All models (including those with an economizer) are suitable

for either bottom or horizontal duct connections. Models with

factory installed power exhaust are suitable for bottom

duct connections only. For bottom duct, you remove the

sheet metal panels from the supply and return air openings

through the base of the unit. For horizontal duct, you replace

the supply and return air panels on the rear of the unit with a

side duct flange accessory.

•

Lead-Lag - An integrated Lead-Lag option allows

equal run time hours on all compressors, thereby

extending the life of all compressors. This option is

selectable on the unit control board.

Fan Delays - Fan on and fan off delays are fully pro-

grammable. Furthermore, the heating and cooling

fan delay times are independent of one another. All

units are programmed with default values based

upon their configuration of cooling and heat.

All models are available with these “factory mounted” outdoor

air damper options:

•

Single enthalpy economizer

•

Safety Monitoring - The control board monitors the

high and low-pressure switches, the freezestats, the

gas valve, if applicable, and the temperature limit

switch on gas and electric heat units. The unit con-

trol board will alarm on ignition failures, compressor

lockouts and repeated limit switch trips.

Single enthalpy economizer with power exhaust

Motorized outdoor air damper

A fixed outdoor air intake assembly will be shipped in the

return air compartment of all units ordered without an econo-

mizer or motorized outdoor air damper option. The assembly

includes a rain hood with a damper that can be set for 10, 15

or 25% outdoor air. With bottom duct connections, the intake

damper assembly should be mounted over the opening in the

return air panel. With horizontal ductwork, it should be

mounted on the return air duct.

Nuisance Trip Protection and Strikes - To prevent

nuisance trouble calls, the control board uses a

“three times, you’re out” philosophy. The high and

low-pressure switches and the freezestats must trip

three times within two hours before the unit control

board will lock out the associated compressor.

All supply air blowers are equipped with a belt drive that can

be adjusted to meet the exact requirements of the job. A high

static drive option is available for applications with a higher

CFM and/or static pressure requirement. A variable air vol-

ume (VAV) option using a variable frequency drive is avail-

able for applications requiring a constant supply duct

pressure. A differential pressure transducer is used to moni-

tor supply duct static pressure and return a speed reference

signal to the VFD to control the output of the indoor blower

motor.

On Board Diagnostics - Each alarm will energize a

trouble light on the thermostat, if so equipped, and

flash an alarm code on the control board LED. Each

high and low-pressure switch alarm as well as each

freezestat alarm has its own flash code. The control

board saves the five most recent alarms in memory,

and these alarms can be reviewed at any time.

Alarms and programmed values are retained

through the loss of power.

All units have long lasting powder paint cabinets with 1000

hour salt spray test approval under ASTM-B117 procedures.

All compressors include scroll compressors and internal pres-

sure relief. Every refrigerant circuit includes an expansion

valve, a liquid line filter-drier, a discharge line high pressure

switch and a suction line with a freezestat and low pressure/

loss of charge switch to protect all system components. A hot

gas bypass option, consisting of an adjustable compressor

discharge bypass valve, is available for low cooling load

applications.

All models are CSA approved.

•

Warranty - All models include a one-year limited parts

warranty on the complete unit. Compressors and electric

heater elements carry a five-year warranty. Gas heat

exchangers carry a 10-year parts warranty.

•

S implicity® Controls - S implicity® control boards have

standardized a number of features previously available

only as options or by utilizing additional controls.

•

Gas Heat Operation - All gas heat units are built with

two heating sections for two equal stages of capacity

control. Each section includes a durable heat exchanger

order to use the indoor blower tables for high altitude applica-

tions, certain corrections are necessary.

CFM, STATIC PRESSURE, AND POWER - ALTI-

TUDE AND TEMPERATURE CORRECTIONS

A centrifugal fan is a "constant volume" device. This means

that, if the rpm remains constant, the CFM delivered is the

same regardless of the density of the air. However, since the

air at high altitude is less dense, less static pressure will be

generated and less power will be required than a similar

application at sea level. Air density correction factors are

shown in Table 7 and Figure 2.

The information below should be used to assist in application

of product when being applied at altitudes at or exceeding

1000 feet above sea level.

The air flow rates listed in the standard blower performance

tables are based on standard air at sea level. As the altitude

or temperature increases, the density of air decreases. In

The examples below will assist in determining the airflow per-

formance of the product at altitude.

blower tables to select the blower speed and the BHP

requirement.

Example 1: What are the corrected CFM, static pressure,

and BHP at an elevation of 5,000 ft. if the blower performance

data is 6,000 CFM, 1.5 IWC and 4.0 BHP?

Solution: As in the example above, no temperature informa-

tion is given so 70°F is assumed.

The 1.5" static pressure given is at an elevation of 5,000 ft.

The first step is to convert this static pressure to equivalent

sea level conditions.

Solution: At an elevation of 5,000 ft., the indoor blower will

still deliver 6,000 CFM if the rpm is unchanged. However,

Table 7 must be used to determine the static pressure and

BHP. Since no temperature data is given, we will assume an

air temperature of 70°F. Table 7 shows the correction factor

to be 0.832.

Sea level static pressure = 1.5 / .832 = 1.80"

Enter the blower table at 6000 sCFM and static pressure of

1.8". The rpm listed will be the same rpm needed at 5,000 ft.

Corrected static pressure = 1.5 x 0.832 = 1.248 IWC

Corrected BHP = 4.0 x 0.832 = 3.328

Suppose that the corresponding BHP listed in the table is 3.2.

This value must be corrected for elevation.

Example 2: A system, located at 5,000 feet of elevation, is to

BHP at 5,000 ft = 3.2 x .832 = 2.66

deliver 6,000 CFM at a static pressure of 1.5". Use the unit
