Features And Benefits - GE ZONELINE 2800 Data Manual

Features and Benefits

Standard Physical Dimensions
GE has maintained the same dimensions since 1961 —
42" wide x 16" high x 1-/4" deep
Replacement of older units is made easy.
Weather-Protected Electrical Components
Vital electrical components are protected from the weather
by locating them on the indoor side of the weather barrier.
Weather-Resistant "Superseal"
Properly installed unit in undistorted case keeps air leakage
to a minimum.
7 CFM air infiltration with 25 MPH wind on non-ICR units —
10 CFM on units with ICR.
Industry specification is 19 CFM of air infiltration.
Heater Sizes to Meet Room Requirements
All units are equipped with a universal heater —
the resistance heat output is determined by power
connection kit.
20/208-volt — Line Cord Connected Units — 2.55/2.09 KW
with RAK15 — 15-amp circuit; .45/2.82 KW with
RAK20 — 20-amp circuit; 5.0/4.09 KW with RAK0 —
0-amp circuit.
20/208-volt - Sub-Base Connected Units — 2.55/2.09
KW with RAK204D15P — 15-amp circuit; .45/2.82 KW
with RAK204D20P — 20-amp circuit; 5.0/4.09 KW with
RAK204D0P — 0-amp circuit.
265-volt — 2.55 KW with RAK5172 — 15-amp circuit; .45 KW
with RAK5202 — 20-amp circuit; 5.0 KW with RAK502 —
0-amp circuit.
Unit Controls
2800 and 800 Series — locked-in-place rotary knobs for
temperature and operation selection.
5800 Series — touch pad controls with digital readout of
temperature set point.
Highly Featured Microprocessor Controls
Microprocessor controls are programmed to interface with
the temperature sensors to maximize comfort conditions for
the room occupant and provide outstanding features.
Thermistors are used to sense small changes in temperature
to give excellent room control and allow the microprocessor
to monitor and react to changing conditions.
Electric Resistance Heat Lock-Out
To maximize the savings of the heat pump operation, the
Zoneline heat pumps do not utilize the resistance heater
when the outdoor temperature is above 46°F during normal
operation. The resistance heat is used in the Quick Heat
Recovery feature.
Automatic Emergency Heat
Automatically uses electric resistance heat if the heat
pump output is not sufficient to maintain selected
room temperature.
Reverse Cycle Heat Pump Defrost System
Standard on all Zoneline 800 and 5800 Series heat pumps.
Enables heat pump to operate at lower temperatures
when other systems switch to more expensive electric
resistance heat.
See pages 18 and 19 for discussion of heat pump operation
and defrost systems.
High Temperature Heat Pump Operation Protection
Automatically protects the compressor if heat pump is
operated with high outdoor temperatures.
Power to the outdoor fan is turned off if the indoor coil gets
too hot during heat pump operation to prevent damage to
the compressor.
Quick Heat Recovery – Heat Pump Units
When the unit operation is changed from STOP or COOL to
HEAT, the electric resistance heaters are used to warm the
room to the thermostat set point. This provides faster room
temperature increase for greater guest comfort.
Unit Diagnostics
The 5800 Series has a dip switch that activates each of
the various components of the unit to operate briefly. This
enables the technician to determine if individual components
are functioning properly.
Service Indicator
On the 5800 Series, if the microprocessor detects a
compressor malfunction, the digital temperature display
will blink. If the malfunction occurs during cooling operation,
the indoor fan will continue to operate. If the compressor
malfunctions in heating mode, the unit will automatically
switch to resistance heat to maintain room temperature set
point. GE Service should be called to check the Zoneline.
Fan Motors – Permanently Lubricated
All units have two fan motors for quiet operation and
maximum operating efficiency.
Motors are permanently lubricated to reduce maintenance
and totally enclosed to keep dirt and water out of the motor
windings.
2-Speed Outdoor Fan
The unit automatically selects the most efficient speed for
the outdoor fan. The operating sound level is lower when the
outdoor fan can operate in low speed yet there are situations
where it must operate in high speed. The unit changes the
fan speed automatically.
Indoor Fan Speed Selections – HIGH/LOW
Unit may be operated in HIGH HEAT or LOW HEAT or HIGH
COOL or LOW COOL.
