f , � <br /> By moving a pin on the board, the user can have electric heat operating during the defrost cycle or not operate. <br /> 9-Circuit - The user can move a pin on the baard to contro! whether the electric heat will aperate simultaneousiy <br /> with the compressor. <br /> Inataor Btower Speed Contral - a speed contra! patentiometer mounted on the board aliows the user to vary the <br /> blower speed on the AVPA heat pumps from 40°lo ta S00°Jo of rated air fiow. (Not appiicable ta the HVPA and HVPSA <br /> units with the electronica(ly commutated indoor blower motor}. <br /> Ventilation Darrtper Re{ay-The board has a dedicated relay to cantrnl a two positioa - Open &Closed - motorized <br /> fresh air damper (Venti{ation Configuration "B"). <br /> ���������� � ��� �������� �� �� ������� <br /> Ffigh Refrigerant Pressure Switch -The high pressure switch is located on the liquid Iine. It is electrically connected <br /> to the PC board and will turn the compressor off if the pressure rises above the set point twice within one hour. This <br /> protects the compressar if airflow is significantly reduced or lost through the coil performing the condenser function. <br /> Loss of Charge SwiYch - The loss of charge switch is located on the liquid line: It is electricaliy connected to the PC <br /> board and will turn the compressor off if the pressure drops above the set point twice within one hour. This protects <br /> the compressor if airFlow is significantly reduced or lost through the coil performing the evaporator function or there <br /> is a loss of refrigerant. <br /> � ���� �� � � � ���� <br /> Marvair� options can be used to provide optimum performance over a full range of operating canditians. <br /> Adjustable Outdoar Thermostat - Wil! not allow electric resistance heat to_ be energized unless the autdoor <br /> temperature is befow the desired set point. Field or factory installed. Avai{able on all CfassicT"� units. <br /> Energy Management System (EMS) Relay Kit -Relay ta controf the unit. Available in 24, 120 ar 240 VAC. Field <br /> or factory installed. <br /> Electric Reheat - Gontrot provides simultaneous operation of compressor when in cooling mode and the electric <br /> elements to provide dehumidification without over cooling the room. The efectric element{kW) must be properly sized <br /> for each model for proper operation. Factory installed. Available on aEl ClassicT"' units. Consult factory for details. <br /> Phase Monitor- Manitars 3� power supply and will turn the air conditioner off if power supply is not phased properly. <br /> Not required on 1� units, <br /> �ompressor sound jackets - Reduces sound af compressor <br /> ������ ����������� �������� ����' ���� ��������� <br /> Caastal Environmental Package - Recommended for units to be instalfed near an ocean or on seacaast. Includes <br /> corrasion resistant fasteners, sealed or partially sealed condenser fan motor, protective coating applied to all exposed <br /> internal copper and metal in the condenser section and a protective coating on the candenser cail. See Coastal <br /> Environmental Technical Bulletin far more details. <br /> Protective Coif Caatings-Either the condenser or evaporator cail can be coated, However, caating af the evaporator <br /> coil is not common. Far harsh conditions, e.g., power plants, paper milis or sites were the unit wili be exposed to saEt <br /> water; the coil shouid be coated. Note: Cooling ca�acity may be reduced by up to S% or� units with coated coils. <br /> � 5 Gassic AVP;i24-30-36-42-48-6G.HVPF2?-3C3@-42-49-60&HVPSA36-42-49•6�PDS 102C15 r2v.6 <br />
