Flat top unitsmeet the traditional requirements for a rugged unit. Slope topunits offer a modern look. The high silhouette unit is 25" (635mm)high and the low silhouette unit is only 22 1 ⁄2" (572mm) high. Theoverall unit dimensions are very compact; unit sizes 004 through012 are 46" (1168mm) long and sizes 013 through 019 are 54"(1372mm) long. All units are a constant 10 3 ⁄4" (273mm) deep forminimum floor space and a consistent “look” for all unit sizes.All units incorporate a slide-out chassis concept which ispreferred by many owners, developers and contractors. Theback part of the cabinet (backwrap) is attached to the subbaseand secures to the back wall or floor. The front cabinet simplylifts off, exposing the chassis for field hook-up of water andelectrical connections. The chassis easily slides off the subbasefor service or changeout.CabinetAll cabinets are painted with Antique Ivory baked enamel finishfor a great match to any room. The discharge grilles and subbaseare Oxford Brown on flat top units.The shallow 22˚ slope top cabinet is constructed of 18-gaugesteel. The side pieces are constructed of ABS polycarbonatewith accent lines to match the grille. The grille and door arealso of ABS polycarbonate with unique detail. The “raised” grilleextends to the front and sides for a smooth look as well asproviding a curtain stop in back. Again, the accent lines on thesides follow the grille and control door lines. The discharge grillesdirect the air in an 11˚ angle from the vertical and can be reversedfor a 33˚ discharge angle. The control door has a finger slot andsimply lifts up for access to the controls. Overall, the slope topunit allows minimal airflow interference from curtains and objectsresting on the cabinet while at the same time providing a rugged,aesthetically pleasing look.The flat top cabinet is constructed of 18-gauge steel with aone piece steel grille that meets basic needs with its ruggedconstruction and its 11˚ discharge angle.Discharge Grille – Flat Top UnitsOne-piece stampedCatalog 1140 / Page 5 of 32

Design FeaturesSlope Top Console UnitSimple Tap-touch OperationChassisThe slide-out chassis houses the fan section, refrigerant circuitand controls. The air enters through the bottom of the chassisthrough the subbase.The refrigeration system includes a rotary compressor,reversing valve, coaxial heat exchanger, capillary tubes, air coil,high and low side access valves, and safety controls. Accessto the compressor is through a panel. The compressor is isolatedfrom the unit with external vibration mounts and thecompartment is totally insulated. Electrical controls include aunit-mounted return air thermostat, start-stop rocker switch andtwo-speed fan control. The operative controls include athermostat adjustment knob for “warmer-cooler” and membranesystem/fan switches for simple tap-touch operation. Safetycontrols include low temperature (freezestat) and refrigerant highpressure switches. The control box top is removable for accessto all of the controls. Two unique control systems are offered:Mark IV and MicroTech. Each uses a printed circuit board forclean wiring and a low voltage control circuit with a 50 VAtransformer. See “Controls” section for more detailedinformation. Main power is made to a chassis-mounted 2" x 4"(51mm x 102mm) junction box.The fan section includes single or multiple split fan housingsfor motor/wheel removal, two-speed PSC motor for selectableairflow and/or noise level. Access to the fan section is madethrough a large insulated panel. The motor is isolated from thechassis with rubber end ring grommets.Water piping connections are 1 ⁄2" FPT fittings which terminatein the down position in the center of the piping compartmentfor easy access. Unique left- and right-hand piping (includescondensate and electrical) locations are available. The 3 ⁄4"(19mm) I.D. flexible clear vinyl condensate drain tube is internallytrapped and extends 14" (356mm) into the piping compartmentfor easy connection. Piping (electrical and condensate also) canenter through the back wall within the backwrap or through thefloor within the subbase. The compact size of the chassis allowsfor a large piping compartment between the chassis and thecabinet.Flat Top Console UnitOptional factory installed featuresBoilerless System electric heat eliminates the need for a boilerin the heat pump water loop. An electric heater is added to thedischarge side of the fan housing(s). If the entering watertemperature falls to 58˚F (15˚C) the thermostat locks outcompressor operation. On a call for heat, the electric heater isenergized. When the entering water temperature raises, the unitwill resume compressor operation on a call for heat. Anemergency heat switch allows electric heating if the compressorshould ever fail. Each unit has various heater sizes to selectfrom. Not available on 115 volt units. Not CSA listed.Page 6 of 32 / Catalog 1140

Control FeaturesThe Mark IV/AC control system is a microprocessor-basedcontrol board conveniently located in the unit control box foraccessibility. Mark IV/AC controllers include a 14-pin low voltageterminal strip for a hardwired interface for all the necessaryfield connections. LED’s are located in front for quick inspection.The board can be wired for 24-volt AC output to the wallthermostat by using terminals R & C. If a DC voltage output tothe thermostat is required, use terminals F & V. This allows youto choose the control output voltage to accommodate controlsby others or accessories.The Mark IV/AC control system has the following operatingfeatures (assumes cycle fan operation-not continuous fan operation):■ Start-up – The unit will not operate until all the inputs andsafety controls are checked for normal conditions.■ Cooling Mode – On a call for cooling, the compressor andfan will start 0 to 32 seconds later. When the load is satisfied,the compressor and fan shut off immediately.■ Heating Mode – On a call for heating, the reversing valveis energized after 60 seconds and the compressor and fanstart immediately. When the load is satisfied, the compressorand fan shut off immediately. The reversing valve is deenergized60 seconds later to eliminate “swish” noise andto allow the compressor to always start up at equalized pressure.■ Short Cycle Protection & Random Start – Each time thecompressor stops, a new random compressor start-delaytime between 180 and 212 seconds is generated. This preventscompressor short cycling and prevents units from startingsimultaneously after coming back from an unoccupiedcycle.■ Unoccupied Mode – A simple “grounded” signal, no powersource required, puts the unit into the unoccupied mode fornight setback operation. The fan shuts off and the unit controlsto the setpoint from the setback bulb of the thermostat.The day heating thermostat control and cooling is lockedout. A unique LED status is generated to indicate the unoccupiedmode. On a call for heating, the fan and the compressorstart after 60 seconds.■■■■■■■Override Mode – A switch on the deluxe automaticchangeover thermostat can be activated during the unoccupiedmode to put the unit back into the occupied modefor two hours for after-hours heating or cooling.Pump Restart – A signal from the Mark IV/AC board to ourLoop Water Control Panel will restart the water circulatingloop pump when the compressor is energized. The signalcan be “daisy chained” between 200 units.Load Shed – A simple grounded signal puts the unit intothe load-shed mode. The compressor shuts off and the fanstarts on a call for heating and cooling. A unique LED statusis generated to indicate the load-shed mode.Brownout Protection – The Mark IV/AC board measuresthe input voltage and will suspend compressor and fan operationshould the voltage fall below 80% of the normal linevoltage. A unique LED status is generated and an output isavailable to a “fault” LED at the thermostat.Unit Shutdown – A simple grounded signal puts the unitinto the shutdown mode. Compressor and fan operationsare suspended. A unique LED status is generated and anoutput signal is made available for connection to a “fault”LED at the thermostat.Condensate Overflow Protection – The Mark IV/AC boardincorporates a liquid sensor at the top of the drain pan. Uponsensing water flow, cooling operation is suspended. A uniqueLED status is generated and output is available to a “fault”LED at the thermostat. Heating operation is not suspended.Safety Control – The Mark IV/AC board receives separateinput signals from the refrigerant high-pressure switch andthe low suction temperature (freezestat) switch. In a highpressuresituation, compressor operation is suspended. Ina low temperature situation, the unit goes into a defrost cyclewhere the unit is put into cooling operation for 60 secondsuntil the coaxial heat exchanger is free of ice. Each switchgenerates its own unique LED status and output is availableto a “fault” LED at the thermostat if either situation exists.For additional protection, units have a 7psi (48 kPa)low pressure switch to protect the compressor from low refrigerantcharge. The low setting prevents nuisance tripswhile providing additional protection.TestingThe Mark IV/AC board allows service personnel to eliminatethe time delays for faster diagnostics. The output terminalsand exposed quick-connect terminals allow troubleshootingwith a voltmeter.Mark IV/AC LED & fault outputsIndicationLEDFaultYellow Green Red OutputNormal Mode Off On Off OffPressure Fault Off On Flash OnLow Temperature Fault* Flash Off Off OnCondensate Overflow** On Dim Off OnBrownout Off Flash Off OnLoad Shed Off Off On OffUnoccupied Mode On On Off OffUnit Shutdown Off Flash Off On* Only in the heating mode ** Only in the cooling modeCatalog 1140 / Page 7 of 32

Loop Water ControllerThe Loop Water Controller (LWC) is a stand-alone, factoryprogrammed and tested microprocessor-based controller providingcontrol of the heat rejection/heat addition stages and thewater circulating pumps for control of a water source heat pumpsystem through solid-state output relays. The controller includesa keypad and display to view all status conditions, temperatures,setpoints and alarm conditions. The display is two lines by sixteencolumns and supports a supertwist LCD format. The LWCis designed to be used with the Mark IV unit controllers forstandalone operation of the water loop. The LWC does not supportserial communications with a higher lever BAS.The LWC can be used in any of the following applications: atraditional single loop system, a closed-circuit evaporative cooler,boiler, primary pump and standby pump system, or a two-loopsystem with the heat pump loop having a boiler, primary pumpand standby pump separated by a water-to-water heat exchangerto a condenser water loop with an open cooling tower, primary(stage 1) pump and a standby (stage 2) pump. The pumps canbe operated as “auto” or “manual” lead-lag. Pump sequencingallows the standby pump to automatically come on upon failureof the lead pump as indicated by a flow switch.The LWC can control heating and cooling stages from theheat pump loop supply temperature and from the outdoor airtemperature for reset of the heat addition setpoint. Other temperaturesthat can be monitored include: the heat pump loopreturn temperature, entering and leaving tower temperatures,entering and leaving boiler temperatures, and the storage tanktemperature.Clock schedule outputs are built-in to (1) control the heatpump circulating pump for shutdown at night (can be restarted ifoutdoor air temperature falls below the setpoint) and (2) provideprogrammable time schedules for heat pump unit occupied/unoccupiedoperation. A maximum of six time clock schedule outputsare available.Two LWC models are available. LWC-16 and LWC-24 provide9 and 17 configurable outputs, respectively, choosing betweenheat rejection (cooling) stages, heat addition (heating)stages and time clock schedules. Each heating and cooling outputhas individual on and off (differential) setpoint adjustmentcapability. Modulating heating and cooling output signals areavailable to control tower bypass and two-way or three-way boilerheat addition valves.Monitored system points include visual and audible notificationof low water temperature, high water temperature, or noflow conditions. When an alarm condition occurs, the LWC closescontacts which can be tied to an emergency shutdown signal. Aremote alarm panel is available for alarm notification at a remotelocation. The LWC interfaces with Mark IV/AC controlledheat pump units for a low cost control system. The Mark IV/ACboard can receive occupied/unoccupied time clock scheduleoutputs and an emergency shutdown signal due to an alarmcondition. The LWC can receive a signal (pump restart) from theMark IV/AC board to energize and override the main circulatingpump (if it is scheduled off) whenever a compressor operatesfrom a call for night setback heat or from a call for heating orcooling during the two-hour override cycle. Simple “daisy chain”wiring is required between Mark IV/AC board terminals on eachwater source heat pump.Additional features include a built-in test mode to simulateall control modes, a pre-cool cycle to enable heat rejection earlierfor undersized boilers, a preheat cycle to enable heat additionearlier for undersized towers, keypad password protection,and holiday scheduling.The LWC panel is not designed to communicate with a higherlevel BAS.Mark IV/AC InterfaceInputsHeat Pump Supply Loop TempHeat Pump Loop Flow SwitchOutside Air TempOptional Temperature SensorsOptional Condenser Loop Flow SwOptional Condenser Loop TempLoop WaterControllerUnitShutdownUnoccupiedSchedulePump StartOutputsHeat Pump Loop PumpsCondenser Loop PumpsHeat Rejection StagesMod.
