<br />SECTION 239500 - MULTI - INDOOR VRV SYSTEM
<br />i. The Daikin wall mounted, hard wired remote sensor kit is recom-
<br />mended for ceiling- embedded type fan coils, which often result in a
<br />difference between set temperature and actual temperature. The sen-
<br />sor for detecting the temperature can be placed away from the indoor
<br />unit (branch wiring is included in the kit).
<br />4.04 FXMQ_PA - CONCEALED CEILING DUCTED UNIT (Med. Static)
<br />A. General: Daikin indoor unit FXMQ_PA shall be a built -in ceiling concealed
<br />fan coil unit, operable with refrigerant R -410A, equipped with an electronic
<br />expansion valve, direct -drive DC (ECM) type fan with auto CFM adjustment
<br />at commissioning, for installation into the ceiling cavity. It is constructed of a
<br />galvanized steel casing. It shall be available in capacities from 7,500 Btu /h to
<br />48,000 Btu /h. Model numbers are FXMQ07PAVJU, FXMQ09PAVJU,
<br />FXMQ12PAVJU, FXMQ15PAVJU, FXMQ18PAVJU, FXMQ24PAVJU,
<br />FXMQ30PAVJU, FXMQ36PAVJU, FXMQ48PAVJU, and FXMQ54PAVJU to
<br />be connected to outdoor unit model RXYQ / RXYMQ / RWEYQ heat pump
<br />and REYQ / RWEYQ heat recovery model. It shall be a horizontal discharge
<br />air with horizontal return air configuration. All models feature a low height
<br />cabinet making them applicable to ceiling pockets that tend to be shallow.
<br />Computerized PID control shall be used to control superheat to deliver a
<br />comfortable room temperature condition. The unit shall be equipped with a
<br />programmed drying mechanism that dehumidifies while limiting changes in
<br />room temperature when used with Daikin remote control BRC1 E72,
<br />BRC1 E73 and BRC2A71. Included as standard equipment, a condensate
<br />drain pan and drain pump kit that pumps to 18 -3/8" from the drain pipe open-
<br />ing. The indoor units sound pressure shall range from 29 dB(A) to 43 dB(A)
<br />at low speed measured 5 feet below the ducted unit.
<br />B. Performance: Each unit's performance is based on nominal operating condi-
<br />tions:
