Part 2 - Products
2.01 Equipment
	A.	General:
Indoor, direct-expansion, wall-mounted fan coil. Unit shall be complete with coil, fan, fan motor, piping connectors, electrical controls, microprocessor control system, and integral temperature sensing. Unit shall be furnished with integral wall mounting bracket and mounting hardware.

	B.	Unit Cabinet:
Cabinet discharge and inlet grilles shall be attractively styled, high-impact non-metallic material.
 
	C.	Fans:
	1.	Fan shall be tangential direct-drive blower type with air intake at the top of the unit and discharge at the bottom front. Automatic, motor-driven vertical air sweep shall be provided standard. 
	2.	Vertical air sweep operation shall be user selectable using the remote control and the horizontal air direction may be set manually.
 
	D.	Coil:
Coil shall be copper tube with aluminum fins and galvanized steel tube sheets. Fins shall be bonded to the tubes by mechanical expansion and specially coated for enhanced wet-ability.  A drip pan under the coil shall have a factory installed drain connection (on both ends) for hose attachment to remove condensate.  
	E.	Motors:
Motors shall be totally enclosed, permanently lubricated ball bearing with inherent overload protection. Fan motors shall be inverter controlled variable speed.
	F.	Controls: 
Controls shall consist of a microprocessor-based control system which shall control space temperature, determine optimum fan speed, run self-diagnostics, provide save mode and self-cleaning. The temperature control range shall be from 62°F to 86°F.
User interface with the unit shall be accomplished through an accessory wired or wireless remote control (can be configured for °F or °C). The wired remote control shall be capable of running system diagnostics (displays operating conditions of the system)

The unit shall have the following functions as a minimum:
	1.	Selectable automatic restart, after power failure the system will restart at the same operating conditions as before the failure. 
	2.	A timer function to provide a minimum 24-hour timer cycle for system Auto Start/Stop.
	3.	Temperature-sensing controls shall sense return air temperature at the unit or at the remote control
	4.	Indoor coil freeze protection in both cooling and heating (reversing valve failure) modes. 
	5.	Automatic air sweep control to provide multiple operating modes of the air sweep louvers.  
	6.	Dehumidification mode shall provide increased latent removal through total system modulation.
	7.	Fan-only operation to provide room air circulation when no cooling is required. 
	8.	Diagnostics shall provide continuous checks of unit operation and warn of malfunctions. Error messages shall be displayed at the unit or the remote control. 
	9.	Fan speed control shall be user-selectable: high, medium, low, or microprocessor determined based on the differential between the room temperature and the set point during all modes of operations.
	10.	Automatic changeover control shall include an adjustable dead band to prevent rapid mode cycling between heating and cooling. 
	11.	Indoor coil high temperature protection shall be provided to detect excessive indoor discharge temperature in heating.
	12.	Cold blow prevention in heating.
	13.	Adjustable compensation for air stratification in heating.
	
G.	Filters: 
Unit shall have factory-supplied cleanable filters, with adjustable filter cleaning reminder on wired remote control 
	
	H.	Electrical Requirements: 
Indoor units are 208/230-1-60 and are powered from the outdoor unit.
	J.	Operating Characteristics:
The systems shall have an SEER in the range of 16.7 to 19.5, and an HSPF in the range of 9.8 to 11.5. For specific system ratings refer to the AHRI directory.
	K.	Special Features (Accessories):
	1.	User Interface can be accomplished with: 
-	Wireless remote control
-	Wired remote control (programmable or non-programmable) shall be capable of controlling from 1 to 8 daisy-chained units.
            2. Condensate pump and installation kit.
