Better Ecology...

Indoor air quality (IAQ) features for the indoor environment

• A double-sloped stainless steel drain pan with a single drain connection ensures that all condensate is voided from the drain pan. It is also visible and accessible for periodic inspection and cleaning re-

quired by the ASHRAE 62 IAQ standard.

• Double-wall construction of the roof, oor, doors, and walls prevents insulation bers from entering the conditioned air. The inner liner

also facilitates periodic cleaning of the unit to prevent harmful build-up of bacteria or contaminants.

• The single package unit control center uses microprocessor logic to analyze and optimize ventilation decisions and perform de-

mand ventilation, airow compensation, and airow measurement to maintain the air quality at a healthy level.

Features and Benefits (Cont'd)

Modulating Powered Exhaust with a VFD – This option consists of a VFD to modulate the speed of the exhaust fan to control the flow of exhaust air. The VFD control logic is based on the building static pressure setpoint within the single package unit controller. The static pressure transducer is provided in the return plenum of the single package unit, and 5/16inch or 1/4-inch plastic tubing and static pressure sensor must be supplied by others and installed in a representative location in the building.

Powered Return Fan with Exhaust – This option uses single width, single inlet (SWSI) plenum fan(s) to control building pressure. The fan motors are driven by a VFD to maintain a constant return plenum pressure. An exhaust hood with a modulating control damper is used to maintain building pressure via the building static pressure. The static pressure transducer is provided in the return plenum of the single package unit, and 5/16-inch or 1/4-inch plastic tubing and static pressure sensor must be supplied by others and installed in a representative location in the building. The powered return fan is also available without the exhaust capabilities. For units with no exhaust capabilities, the HVAC system must provide alternate means of controlling building pressure.

SUPPLY FAN OPTIONS

Double Width, Double Inlet (DWDI) Airfoil Supply Fan – The standard airfoil blade sup-

ply fan is available on all models for higher static conditions. This offers higher efficiency and lower sound in certain applications.

Fan Skid Isolation – The entire supply fan assembly is isolated from the unit base with either 1-inch (standard) or 2-inch deflection springs with seismic restraints.

FORM TPM3-EG1 (518)

Double-Wall Construction – Double-wall construction is the standard construction of the TempMaster OmniElite and incorporates powder coated pre-fabricated outer panels and corner post for maximum exterior surface protection.

Factory Shrink-Wrap – All TempMaster OmniElite single package units are shipped from the factory with factory-fresh shrink-wrap packaging. No longer does the contractor need to worry about dirt and debris clogging up condenser coils or moisture leaking into the air handler on the units way to the job site or rigging yard.

Copper Fins – For more extreme climates that aggressively can attack aluminum, copper tube evaporator coils with copper fins are available. (This is not recommended for units in areas where they may be exposed to acid rain or environments where ammonia is present.)

CONDENSER FEATURES AND OPTIONS

Scroll Compressors – Reliable, efficient, trouble-free operation is the true measure of

a single package unit’s value. That’s why TempMaster OmniElite single package units use established scroll compressor technology to deliver dependable, economical performance in a wide range of applications. With the TempMaster OmniElite single package units, you get the latest generation of compressor enhancements added to the scroll’s inherent strengths. The simplicity of a hermetic scroll compressor allows the use of fewer moving parts to minimize breakdown.

Compressor Circuiting – The TempMaster OmniElite is designed so that only two scroll compressors are in tandem within one refrigeration circuit. This means more reliable com-

pressors, and less equipment down time. With multiple circuits, if a compressor should

ever fail on one circuit, the other circuit/s will remain operational to work to maintain occupied loads. The TempMaster OmniElite system has three circuits in a unit.

Compressor Staging - The TempMaster OmniElite refrigeration system is equipped with a unique staging algorithm. On first call for cooling the system calculates the amount of

cooling capacity needed by the space and automatically brings on enough cooling capacity to meet this calculated need. Comfort cooling is provided quickly without the lag inherent to staging on additional compressors to meet a high demand. Additionally, due to a three independent circuit design with two compressors on each circuit, the TempMaster OmniElite can provide superior granularity in terms of staging, which translates to best in class part load efficiency or IEER.

Condenser Fan Motors – The condenser fan motors used on the TempMaster OmniElite unit are totally enclosed air over (TEAO) to provide maximum durability through any season.

Replaceable Core Liquid Line Driers – Liquid line driers are standard on the TempMas- ter OmniElite single package unit.

Post-Coated Condenser Coil Fins – Technicoat coil-coating process used on condenser coils for seashore and other corrosive applications (with the exception of strong alkalis, oxidizers, wet bromide, chlorine, and fluorine in concentrations greater than 100 ppm).

Compressor Sound Blankets – Optional compressor acoustic sound blankets are available for sound sensitive applications.

for use with wood nailer (by others). Roof curb supports the entire perimeter of the unit.

Partial Perimeter Roof Curbs – This option includes a knock-down 14-inch high roof curb for use with wood nailer (by others). Roof curb supports the air handling section with a separate support under the condenser end.

CABINET FEATURES AND OPTIONS

Double-Wall Access Doors - Full-sized access doors provide easy access into the unit

for routine maintenance and inspection. Solid wall liners encase insulation and prevent damage and erosion into the airstream.

Diffuser Section – An optional diffuser section is available downstream of the supply fan in the extended discharge plenum cabinet option. The diffuser section distributes the airflow from the fan evenly across the downstream filter bank to optimize filter life and effectiveness. The diffuser design is optimized to provide uniform flow at minimal airside pressure loss.

Downstream Final Filter Rack – A 90–95% efficient MERV 14, 12-inch rigid filter rack and filters shall be provided downstream of the supply fan and diffuser segment for hospital applications. A magnahelic pressure gauge is included and visible from the outside of the unit for servicing and code compliance.

Blank Section – A blank section shall be provided downstream of the supply fan and diffuser section.

ACCESSORIES

Filter Switch – An optional dirty filter alarm can be provided that will provide an alarm

when the filters require cleaning.

Magnahelic Filter Pressure Gauge – On units equipped with downstream filtration, a

magnahelic filter gauge is included and visible on the exterior of the unit. The filter gauge measures the air pressure drop for through the rigid filter bank to indicate when replace-

ment is required.

FORM TPM3-EG1 (518)

Application Data

GENERAL

The TempMaster® OmniElite™ air conditioning units are designed for outdoor installation. When selecting a site for installation, be guided by the following conditions:

• Unit must be installed on a level surface.

• For the outdoor location of the unit, select a place having a minimum sun exposure

and an adequate supply of fresh air for the condenser.

• Also avoid locations beneath windows or between structures.

• Optional condenser coil protection should be used for seashore locations or other harsh environments.

• The unit should be installed on a roof that is structurally strong enough to support the

weight of the unit with a minimum of deection. It is recommended that the unit(s) be

installed not more than 15 feet from a main support beam to provide proper structural support and to minimize the transmission of sound and vibration. Ideally, the center of gravity should be located over a structural support or building column.

• Location of unit(s) should also be away from building ue stacks or exhaust ventilators to prevent possible reintroduction of contaminated air through the outside air intakes.

• Be sure the supporting structures will not obstruct the duct, gas or wiring connections.

• Proper service clearance space of 6 feet around the perimeter of the unit, 8 feet on

one side for coil servicing, and 12 feet to any adjacent units is required to eliminate

cross contamination of exhaust and outside air, and for maintenance tasks such as coil pull and cleaning. No obstructions should be above the condensing unit section.

LOCATION

Of the many factors that can effect the location of equipment, some of the most important

to consider are structural, acoustical and service clearances. Proper attention should be

made at the design stage to ensure proper structural support. In cases where equipment is being replaced, be aware of building design to ensure support is adequate for the ap-

plication.

The next most important consideration in applying single package units equipment is that of sound from the equipment. Special care should be made to keep the single package

unit away from sound sensitive areas such as conference rooms, auditoriums and executive offices and any other room that may have potential for tenant occupancy. Possible locations could be above hallways, mechanical or utility rooms.

Finally, service clearances should be maintained in single package unit design to ensure safe access to the unit. Unit clearances are designed so that technicians have enough space between units, building walls, and edges of building to gain access safely. In cases where space is limited, please call a local TempMaster representative for additional information.

TEMPMASTER

FORM TPM3-EG1 (518)

RIGGING

Proper rigging and handling of the equipment is mandatory during unloading and setting

it into position to retain warranty status.

Spreader bars must be used by cranes to prevent damage to the unit casing. All lifting lugs must be used when lifting the single package unit. Fork lifts will damage the single package unit and are not recommended.

Care must be taken to keep the unit in the upright position during rigging and to prevent damage to the watertight seams in the unit casing. Avoid unnecessary jarring or rough handling.

UNIT PLACEMENT

• Elevated – Elevated roof curbs or dunnage steel can be used to support the unit in

order to raise it to specic heights. When this type of placement is required, be sure to keep unit access in mind. Cat walks or other forms of unit access may be required

to one or both sides of the unit, depending on your area of the country and the local

codes that are enforced. Please check with local ofcials to ensure the application

conforms to local codes and regulations.

• Ground Level Locations – It is important that the units be installed on a substantial

base that will not settle, causing strain on the refrigerant lines and sheet metal and resulting in possible leaks. A one-piece concrete slab with footers extended below the frost line is highly recommended. Additionally, the slab should be isolated from the main building foundation to prevent noise and vibration transmission to the building structure.

For ground level installations, precautions should be taken to protect the unit from tampering by, or injury to, unauthorized persons. Erecting a fence around the unit is common practice.

• Roof curb – TempMaster offers optional roof curbs designed specically for the

TEMPMASTER

TempMaster OmniElite footprint. These curbs come in full perimeter or open condenser models and are shipped disassembled and require eld assembly and installation. For bottom supply and return openings, the curbs have matching connections to ease installation. A pipe chase that matches the single package unit pipe chase is also included in the curb footprint for through-the-curb utility connections.

FORM TPM3-EG1 (518)

Application Data (Cont'd)

The curb should be located according to the location recommendations above, and properly sealed to prevent moisture and air leakage into and out of the duct system. Flexible collars should be used when connecting the ductwork to prevent unit noise transmission and vibration into the building.

Ductwork should be supported independently of the unit.

UNIT ORIENTATION

For applications with multiple single package units located in close proximity on the roof, the orientation of the unit may be important to reduce the potential for re-entrainment of outside airflow. Regardless of the outside air and exhaust air openings on a unit, all single package unit applications can permit recirculation of exhaust air to the return, if applied improperly.

HORIZONTAL APPLICATIONS

The spectrum of applications for single package units in today’s market is continuing to grow wider by the day. Flexibility in unit design and construction is a must in today’s mar-

ket in order to ensure safe and sound applications of HVAC equipment. The TempMaster

OmniElite has been designed for specific application of horizontal supply and return airflow taking the guess work out of unit application by building a unit specific to these needs. If the application calls for horizontal supply and return air, TempMaster can ship it from the factory as a horizontal unit. This option eliminates the need for field modification of equipment saving time and money. The TempMaster OmniElite can support a left discharge on all units except electric heat and/or right discharge on all cooling only units and hydronic heat units with an extended cabinet. Return air can be brought through the front or bottom return air inlet making the unit specific to building needs.

ECONOMIZER

The economizer section is used for ventilation of the conditioned space to maintain indoor

air quality (IAQ), and also to reduce energy consumption by using outside air cooling in lieu

of mechanical cooling. If outside air is appropriate for cooling, but not sufficient for the cooling demand, mechanical cooling will stage on as necessary until the cooling load is met.

Dual (comparative or differential) enthalpy operation is the most accurate and efficient means of economizer operation. The IPU controller monitors the return and outside air energy content, and selects the lower of the two for operation.

VARIABLE AIR VOLUME (VAV) SUPPLY AIR PRESSURE CONTROL

Traditional single package unit systems use inlet guide vanes (IGVs) for duct static pressure control. These control supply duct pressure by modulating dampers (introducing losses

and inefficiencies) on the inlet of the fan, open and closed. TempMaster variable frequency drives (VFDs) offer superior fan speed control and quieter, energy efficient operation.

FIGURE 3 - TRADITIONAL OVERHEAD VARIABLE AIR VOLUME (VAV) AIR DELIVERY SYSTEM

For variable air volume (VAV) applications, the TempMaster OmniElite unit uses a VFD to modulate fan speed and maintain a constant duct static pressure. VFDs offer superior control over the operation of the unit at part load, and offer the additional benefits of quieter and more efficient operation when compared to IGV.

BUILDING PRESSURE CONTROL SYSTEMS

Building pressure control systems are often necessary when economizers are used to bring in outside air. Without proper building exhaust, the building may become over pressurized. The pressure control system maintains the proper building pressure by expelling the appropriate amount of air from the building.

TEMPMASTER

FORM TPM3-EG1 (518)

Application Data (Cont'd)

Return fans – For high return static applications, such as buildings with ducted return systems, a powered return fan may be necessary to maintain building pressure control. TempMaster offers a powered return fan that is located in the return plenum. This fan operates coincidentally with the supply fan and draws return air back through the return ductwork and into a pressurized plenum. A control damper modulates to exhaust air out of the building and maintain the building pressure. A second control damper modulates to provide return air from the ductwork to the unit to the single package air mixing section.

The return fan configuration is available in two forms: with and without an exhaust damper. The option with the exhaust damper provides a means of building exhaust at the unit. In some applications, the exhaust system is located elsewhere and the single package unit

is not required to provide building exhaust. In these situations, the TempMaster OmniElite

can be offered without the exhaust damper to help reduce installed costs.

Exhaust/relief fans – In this application, a powered exhaust fan may be suitable, however careful consideration of the fan type is necessary. TempMaster offers a centrifugal powered exhaust fan to perform this function. Some manufacturers use a propeller ex-

haust fan, which cannot handle the static pressure requirements.

For systems with moderate to low return static pressure, an exhaust fan is recommended. The benefit of the exhaust fan is that it does not run all of the time, and may facilitate com-

pliance with the ASHRAE 90.1 fan motor horsepower requirement.

The exhaust fan operates in parallel with the supply fan. In this arrangement, the supply fan handles the full static pressure requirements of the system. For normal building pressure control, the exhaust fan operates to draw air from the return plenum and exhaust it out of the building.

The exhaust fan configuration is available in two forms, modulating and non-modulating. Modulating is the most common and recommended for the majority of applications, while non-modulating should be used in only certain circumstances.

In the modulating exhaust system, the volume of airflow exhausted from the building is proportional to the entering volume of outside air. Control is accomplished via either a discharge damper or a VFD. TempMaster recommends the use of a VFD to reduce energy consumption, sound levels and improved reliability due to fewer moving parts.

In the non-modulating exhaust system, the exhaust airflow is constant whenever the exhaust fan is operating. This type of control should only be used to either assist a smoke

purge system or when a system requires a constant volume of exhaust airflow.

ACOUSTICAL CONSIDERATIONS

The TempMaster OmniElite unit is designed for lower sound levels than competitive units by using flexible fan connections, fan spring isolators, double-wall construction, multiple fan options, and lower speed and horsepower fans. For VAV applications, VFDs are used instead of inlet guide vanes. Additional sound attenuation can be obtained using compressor sound blankets when necessary.

Even with these equipment design features, the acoustical characteristics of the entire

installation must never be overlooked. Additional steps for the acoustical characteristics of a single package unit installation should be addressed during the design phase of a

project to avoid costly alterations after the installation of the equipment. During the design

phase of a project, the designing engineer should consider, at a minimum, the impact of

the equipment location, single package unit installation, building structure, and ductwork.

ELECTRICAL SERVICE SIZING

In order to use the electrical service required for the cooling only TempMaster OmniElite

single package unit, use the appropriate calculations listed below from U.L. 1995. Based on the configuration of the single package unit, the calculations will yield different minimum circuit ampacity (MCA) and maximum overcurrent protection (MOP).

Using the following load definitions and calculations, determine the correct electrical sizing for your unit. All concurrent load conditions must be considered in the calculations, and you must use the highest value for any combination of loads.

Load Definitions:

FORM TPM3-EG1 (518)

• LOAD1 is the current of the largest motor – compressor or fan motor.

• LOAD2 is the sum of the remaining motor currents that may run concurrently with

LOAD1.

• LOAD3 is the current of the electric heaters (Note: zero for cooling only units).

• LOAD4 is the sum of any remaining currents greater than or equal to 1.0 amp.

Use the following calculations to determine MCA and MOP for units supplied with a singlepoint power connection:

If the MOP does not equal a standard current rating of an overcurrent protective device,

then the marked maximum rating is to be the next lower standard rating. However, if the device selected for MOP is less than the MCA, then select the lowest standard maximum

fuse size greater than or equal to the MCA.

CONTROL SEQUENCES

FOR VARIABLE AIR VOLUME (VAV)

AND SINGLE ZONE VAV (SZVAV)

GENERAL

The control system for the TempMaster® OmniElite™ single package unit is fully self-contained and based around a single package unit controller. To aid in unit setup, mainte-

nance, and operation, the single package unit controller is equipped with a user interface

that is based around a 4 line x 20 character backlit liquid crystal display (LCD). The LCD displays plain language text in a menu-driven format to facilitate use.

Based on the unit type (variable air volume (VAV) or single zone VAV (SZVAV)), the TempMaster OmniElite single package units can be operated by a space temperature sensor or standalone. A field wiring terminal block is provided to facilitate unit setup and installation.

In lieu of the hardwired control options, the single package unit controller can be connected to and operated by a building automation system (BAS).

The IPU controller uses the latest technology and provides complete control for the unit along with standard BACnet® MS/TP and Modbus™ remote terminal unit (RTU) communications. The IPU controller also has an SD card slot that can be used to capture historic data on unit operation.

If required, the unit can be equipped with an optional field-installed gateway that allows N2

or Echelon® communications. The E-Link gateway device is field installed and purchased through the advanced order management system (AOMS).

YK-ELNKE01-0 – E-Link for Echelon

YK-ELNKE00-0 – E-Link for N2

UNOCCUPIED/OCCUPIED SWITCHING

Depending on the application, the unit can be indexed between unoccupied and occupied modes of operation by one of three methods, hardwired input, internal time clock, or BAS. A contact-closure input is provided for hardwiring to an external indexing device such as

a central time clock or a manual switch. The unit controller is also equipped with a built-

in 7-day time clock that can be used in lieu of the contact closure input to switch the unit between unoccupied and occupied modes of operation.

The internal time clock is fully configurable via the user interface and includes holiday scheduling. In addition to the hardwired input or the internal time clock, the unit can also be indexed between unoccupied and occupied modes of operation via a BAS command.

GAS HEATING OPERATION

Units supplied with gas heat can be equipped with one, two, or three independently operated burner modules. Each module is fully self-contained furnace with all necessary ignition controls, safeties, and gas valves. The IPU controller determines how the furnaces are started and stopped and prevents furnace operation if the supply fan airflow is not sufficient or if the supply air temperature (SAT) is excessively high. If a furnace module receives a signal to start from the IPU controller, the ignition control engages the furnace inducer (draft) fan for a 30-second pre-purge cycle. At the end of the 30-second prepurge, the ignition control will stop the furnace and allows the inducer fan to operate for a 30-second post-purge. Each furnace contains a direct spark ignition system and included safeties for flame and inducer fan verification, high temperature, and flame rollout.

TEMPMASTER

FORM TPM3-EG1 (518)

Controls (Cont'd)

HYDRONIC HEAT

If the unit is configured with either of the wet heat options (steam or hot water) the single package unit controls will modulate the hydronic valve to maintain a supply air (SA) setpoint. In the event temperatures off the hydronic coil are below 34.0°F, the fans will shut down and the hydronic valve will open 100%. This function is an automatic reset, so as the temperature rises above 36.0°F, the unit will automatically begin normal operation.

ELECTRIC HEATING OPERATION

For units equipped with electric heaters, the unit can control up to six stages of electric

heat, which are staged on based on heating demand calculated by the IPU controller.

MORNING WARM-UP

Morning warm-up can be initialized by BAS or by the IPU controller if the internal scheduling is used. If the internal scheduling is used, the morning warm-up start time is calculated

through an adaptive algorithm. When morning warm-up is required, the IPU controller energizes the VAV heat relay, starts the supply fan and qualifies the return air tempera-

ture (RAT) for 5 minutes. The internal heat source (gas, hot water/steam, or electric) is controlled to maintain the RAT to the return air (RA) heating setpoint, morning warm-up ends when occupancy occurs (BAS, internal scheduling, or contact closure) or when the maximum morning warm-up time has expired.

ECONOMIZER OPERATION

The unit can be equipped with one of three types of optional economizers: dry bulb, single

enthalpy, or comparative enthalpy. When the unit controller determines that outside air is suitable for economizing, the unit controller will control the outside air (OA) damper(s) open to provide economizer cooling. If economizer cooling alone is insufficient for the cooling load, the unit controller shall stage up compressors, one at a time, to meet demand.

The control logic for the three types of economizers is as follows:

Dry Bulb Economizer: The dry bulb economizer is the default economizer control scheme. With the dry bulb economizer, the unit controller monitors the outside air temperature (OAT) only and compares it to a reference temperature setting. Outside air is deemed suitable for economizing when the OAT is determined to be less than the reference temperature setting. This method of economizing is effective, but it is prone to some changeover inefficiencies due to the fact that this method is based on sensible temperatures only and does not take outside air moisture content into consideration.

Single Enthalpy Economizer: With the optional single enthalpy economizer, the unit controller monitors the OA enthalpy in addition to the OAT and compares it to a reference enthalpy setting and a reference temperature setting. Outside air is deemed suitable for economizing when the OA enthalpy is determined to be less than the reference enthalpy setting and the OAT is less than the reference temperature setting. This method of economizing allows the reference temperature setting to be set higher than the dry bulb econo-

mizer and is consequently a more efficient single package unit economizer.

Dual Enthalpy Economizer: With the optional dual enthalpy economizer, the unit controller monitors and compares the OA and RA enthalpies in addition to comparing the OAT to the reference temperature setting. Outside air is deemed suitable for economizing when the OA enthalpy is determined to be less than the RA enthalpy and the OAT is less than the reference temperature setting. This method of economizing is the most accurate and provides the highest degree of energy efficiency for a single package unit economizer.

TEMPMASTER

FORM TPM3-EG1 (518)

VENTILATION CONTROL SEQUENCES

Minimum Outside Air (OA) Damper Position (VAV Units)

With VAV units, there are two minimum OA damper positions: one when the unit is at full speed and the second when the unit is at approximately half speed. These two points allow the control to linearly reset the position of the OA damper in response to fan speed.

When the unit goes into the occupied mode of operation, the unit controller shall monitor the speed of the supply fan and open the OA damper to a calculated minimum position based on the fan speed. This minimum position shall vary as the speed of the fan changes. The damper shall remain at this calculated position as long as the unit is in the occupied mode and the economizer is not suitable for cooling.

Air Measurement Stations

When the unit is equipped with an air measurement station, the unit controller shall control

the OA damper to a measured flow rate through the air measurement station.

When the unit goes into the occupied mode of operation, the unit controller shall control the OA damper to maintain the minimum airflow setpoint through the air measurement station. The unit controller shall control the OA damper to this flow rate as long as the unit is in the occupied mode and the economizer is not suitable for cooling.

Demand Ventilation

If optional carbon dioxide (CO2) sensors are connected to the unit, the unit controller can reset the minimum OA damper position(s) or minimum flow rate based on demand.

The unit controller shall monitor the CO2 level within the building. If the CO2 level rises above the CO2 setpoint, the controller will temporarily increase the minimum OA damper position or minimum OA flow rate to increase ventilation. If the CO2 level drops below the CO2 setpoint, the controller will decrease the minimum OA damper position or minimum OA flow rate to decrease ventilation. Demand ventilation shall remain active as long as the unit is in the occupied mode of operation.

EXHAUST CONTROL SEQUENCES

Barometric

The optional barometric exhaust system consists of a lightweight barometric relief damper installed on the end of the unit in the RA section. As more outside air is introduced into

the controlled zone due to economizer and ventilation control sequences, the pressure

inside the building rises. As building static pressure increases to overcome any exhaust duct static pressure, air will be allowed to escape through the barometric relief damper. Because this type of exhaust is not powered, the amount of air exhausted will be limited to the static pressure that will need to be overcome.

TEMPMASTER

FORM TPM3-EG1 (518)

Controls (Cont'd)

Powered Variable Volume Exhaust - Discharge Damper Controlled

This optional variable volume powered exhaust system consists of a fixed speed fan configured with a proportionally controlled discharge damper. The unit controller monitors the pressure inside the building and controls the exhaust damper and the exhaust fan. If the building pressure rises, the exhaust damper is proportionally controlled open and the exhaust fan is controlled ON. If the building pressure falls, the exhaust damper is proportionally controlled closed and the exhaust fan is controlled OFF. The position of the exhaust damper in which the exhaust fan is controlled ON and OFF as well as the building pressure setpoint are user selectable from the user interface.

Powered Variable Volume Exhaust - VFD Controlled

This optional variable volume powered exhaust system consists of an exhaust fan driven

by a variable frequency drive (VFD), which is controlled by the unit controller. The unit

controller monitors the pressure within the building. As the pressure rises, the VFD is controlled to increase exhaust fan speed. As the pressure falls, the VFD is controlled to decrease exhaust fan speed. The building pressure setpoint is user selectable from the user interface. ON/OFF control is maintained the same as exhaust-discharge damper control stated above.

Return Fan Controlled

This optional variable volume powered return fan system consists of two return fans controlled by one VFD that is controlled by the unit controller. The VFD is controlled to maintain a slightly positive pressure over the mixing box section to prevent reverse flow. As the return and/or exhaust air dampers open, the return plenum pressure drops and the fan will speed up to maintain pressure. When the return and/or exhaust air dampers close, the return plenum pressure increases causing the VFD to slow the fan speed down.

LOW AMBIENT/HEAD PRESSURE CONTROL OPERATION

The unit controller continuously monitors the OAT to determine if mechanical cooling should be allowed. As a safety, if the OAT falls to or below the low ambient lockout temperature, mechanical cooling is prevented from operating. For units with economizers, the low ambient lockout temperature is typically low enough that mechanical cooling will

rarely be required. However, for some applications mechanical cooling is required when

the OAT is lower than the low ambient lockout temperature.

For these applications, the unit must be equipped with optional low ambient controls.

For optional low ambient operation, the unit controller monitors the refrigeration system discharge pressure and takes measures to limit the flow of air across the condenser coil. With the optional low ambient controls, mechanical cooling is allowed down to an OAT of

0.0°F.

SMOKE PURGE SEQUENCES

General

The controls of the TempMaster OmniElite are designed as standard with a ventilation override sequence to remove, exhaust, or ventilate smoke, fumes, or other airborne contaminates from the occupied space. This feature offers three selectable operations: purge,

pressurization, and evacuation. The sequence is activated via one of three binary inputs.

A few typical contact closures include smoke detectors, fire alarms, and manual switches.

TEMPMASTER

FORM TPM3-EG1 (518)

Purge

Note: All cooling and heating modes are disabled during smoke purge.

Purge shall be used to displace the air inside the space with fresh outside air. When this

sequence is started, the following shall occur:

1. Start the supply fan if not already on. (Note: With VAV units, the fan speed shall be

controlled to maintain the active duct pressure setpoint.)

2. Start the return and exhaust fans if not already on.

3. Set the VFD to 100%.

4. Set the OA damper position to 100% and the exhaust damper to 100%.

Pressurization

Pressurization shall be used to pressurize the building or space in order to force the air inside the space through the walls to adjacent spaces or outside the building envelope.

When this sequence is started, the following shall occur:

1. Start the supply fan if not already on. (Note: With VAV units, the fan speed shall be

controlled to maintain the active duct pressure setpoint.)

2. Stop the return and exhaust fans if on.

3. Set exhaust/return fan VFD to 0%.

4. Set the OA damper to 100% and the exhaust damper to 0%.

Evacuation

Evacuation shall be used to evacuate (negatively pressurize) the building or space in order to draw air through the walls from adjacent spaces or outside the building envelope.

When this sequence is started, the following shall occur:

1. Stop the supply fan if on.

2. Start the return and exhaust fans if not already on.

3. Set the exhaust/return fan VFD to 100%.

4. Set the OA damper to 0% and the exhaust damper to 100%.

Unoccupied Cooling – In the unoccupied cooling mode, the unit controller will monitor the zone temperature and compare it to the unoccupied zone cooling setpoint. The unoccupied zone cooling setpoint is set through the setpoints key, cooling subsection of the

user interface. If the zone temperature is equal to or greater than the unoccupied zone

cooling setpoint temperature plus 0.5°F, the unit controller will place the unit in the unoccupied cooling mode. The unit will remain in the unoccupied cooling mode until the zone

temperature is equal to or less than the unoccupied zone cooling setpoint minus 0.5°F.

Unoccupied Heating – In order for the unoccupied heating mode to function, the night set back setting must be set to enable. This can be done through the program key, heating subsection of the user interface. In the unoccupied heating mode, the unit controller will monitor the zone temperature and compare it to the unoccupied zone heating setpoint. The unoccupied zone heating setpoint is set through the setpoints key, heating subsec-

tion of the user interface. If zone temperature is equal to or less than the unoccupied zone
