Friedrich Digital Control Features Continued

InstantHeat	Heat pump models will automatically run the electric heater to quickly bring the room up to temperature when initially energized,
	then return to heat pump mode. This ensures that the room is brought up to temperature quickly without the usual delay associ-
HeatPumpMode
	ated with heat pump units.
EvenHeatMonitoring	The digital control monitors indoor conditions to ensure that the room temperature is within five degrees of the setpoint. If neces-
	sary the unit will cycle the electric heat to maintain the temperature. This feature ensures guest comfort by delivering the heating
	benefits of an electric heater while maintaining the efficiency benefits of a heat pump.
	The owner may choose between fan cycling or fan continuous mode based on property preference. (Note: Even heat monitor-
FanCycle Control	ing and quiet start/stop fan delay only operate in fan cycle mode) Fan continuous mode is used to keep constant airflow circula-
	tion in the room during all times the unit is ‘ON’. Fan cycle will conserve energy by only operating the fan while the compressor
	or electric heater is operating.
EmergencyHeatOverride	In the event of a compressor failure in heat pump mode the compressor may be locked out to provide heat through the resis-
	tance heater. This feature ensures that even in the unlikely event of a compressor failure the room temperature can be main-
	tained until the compressor can be serviced.
DeskControlReady	All Friedrich digital PTACs have low voltage terminals ready to connect a desk control energy management system. Control-
	ling the unit from a remote location like the front desk can reduce energy usage and requires no additional accessories at the
	PTAC.
Indoor CoilFrost Sensor	The frost sensor protects the compressor from damage in the event that airflow is reduced or low outdoor temperatures cause
	the indoor coil to freeze. When the indoor coil reaches 30°F the compressor is diabled and the fan continues to operate based
	on demand. Once the coil temperature returns to 45°F the compressor returns to operation.
Ultra-QuietAirSystem	The new Friedrich PD series units feature a indoor fan system design that reduces sound levels without lowering airflow and
	preventing proper air circulation.
HighEfficiency	The Friedrich PTAC benefits quality components and extensive development to ensure a quiet, efficient and dependable unit.
SingleMotor	Friedrich’s single-motor design allows for enhanced outdoor airflow and simplifies the unit design without the need for redun-
	dant components.
RotaryCompressor	High efficiency rotary compressors are used on all Friedrich PTACs to maximize durability and efficiency.
AuxiliaryFanReady	The Friedrich PTAC features a 24V AC terminal for connection to an auxiliary fan that may be used to transfer air to adjoining
	rooms. Auxiliary fans can provide conditioning to multiple rooms without the requirement of multiple PTAC units.
AluminumEndplates	All Friedrich PTACs are built with .04" endplates made from aluminum as opposed to steel. The endplates are typically the most
	susceptible area for corrosion and aluminum is far more resistant to corrosion than even coated steel.
SeacoastProtection	Optional Seacoast protection is available to protect the outdoor coil from harsh environments. The Friedrich Seacoast process
	includes dipping the entire outdoor coil in a 7-step coating process that provides superior protection to only coating the fins of
	the coil.
TopMountedAnti-	All Friedrich PTAC return air filters feature an anti-microbial element that has proven to prevent mold and bacterial growth in
	laboratory testing. PDXFT replacement filter kits feature the same anti-microbial agent. All filters are washable and reusable
microbialAirFilters
	and are easily accessed from the top of the unit without the removal of the front cover.
FilteredFreshAirIntake	Friedrich PTAC units are capable of introducing up to 70 CFM of outside air into the conditioned space. The outdoor air passes
	through a washable mesh filter to prevent debris from entering the airstream.
