Unit mount-control operation allows the use of an optional IR hand held controller. The control shall have the capability of sensing return air temperature and indoor coil temperature. The operational range will have adjustable set points from 55°F to 90°F in one degree increments. The universal control can be used in cooling only, cooling with optional electric heat, heat pump or heat pump with optional second stage electric heat. Operation modes include, cool, heat, fan, auto change over and dry. Fan operation of auto (cycling), high and low (constant), auto fan operation automatically selects fan speed according to heating or cooling demand. Dry mode operates cooling and optional electric heat simultaneously to remove humidity (optional electric heat required). Test mode allows for ease of testing after installation (all timers are eliminated). Room air sampling (fan auto mode) cycles the fan on periodically to remove temperature stratification. Fan purge runs the indoor fan for 60 seconds after call is dropped for cool/heat, improving unit efficiency. Unit protection features include, anti short cycling compressor protection, minimum compressor run time, freeze protection to prevent evaporator freeze, filter change indicator, condensate pan overflow switch, and integral Rome, New York, USA Enviromaster International LLC 3 EMI ENgINEERINg SUBMITTAL WLH12-S1H2000_101 condensate pump safety-switch connection. With this feature the control monitors the condensate pump safety switch and displays an error code if a fault occurs. The unit shall also provide non-volatile back up memory, where control settings are maintained for an indefinite period during a power outage. When power is restored the equipment will resume operation after a 3 minute compressor time delay. The controlVoltage shall be 24V AC generated from the indoor units transformer. part six “OutDOOr unit” The outdoor unit shall be completely factory assembled, piped and wired.The cabinet shall be fabricated of 18 and 20 gauge aluminized steel, finished in off white. The paint shall be a corrosion inhibiting polyester powder-coated paint tested to 2000 hours of salt spray. The cabinet shall also incorporate a black scratch and dent resistant injection molded from access panel. The unit shall be furnished with (1) large diameter, direct drive, high efficiency propeller type fan. The motor shall be PSC type with internal overload protection and shall be permanently lubricated and resiliently mountedforquietoperation.Thefanshallbeprovidedwithaguardtopreventcontactwithmovingparts.Thecompressor shall be of the high performance rotary type with Duratec package consisting of an oversized accumulator, factory installed solid core filter drier and thermal overloads.
