Frost can form on the indoor coil when the unit is operated in cooling when outdoor temperatures are low. The unit automatically shuts. The electrical power for the operation of the transfer fan itself is not provided by the Zoneline unit.
Transfer fans and their controlling relays are field supplied. Seven independent programmable heating temperature limits and seven independent programmable cooling temperature limits.
All units have a switch via the auxiliary control setting to allow the indoor fan to continue operating if the unit is connected to an energy management system that shuts off compressor or heater operation. By allowing the indoor fan to run when the heater or compressor is shut off by the energy management system, the guest is less likely to realize the operation of the unit has been altered. This helps reduce peak energy demand loads without disturbing the room occupant. Angle is changed by removing room front and screws holding louver in place, and rotating louver section.
Clean filters by brushing, vacuuming or backflushing under faucet or shower head. A concealed lever is located along the left side of the unit under the front cover is used to open and close the vent door.
The 3-position manual vent door control may be closed, partially open or fully open. Positive vent door closure prevents accidental opening and unwanted air infiltration. For each CFM of air to enter the room, an equal amount of air must be removed through exhaust fans in the bathroom or roof tops.
Greater amounts of air will be introduced from chart shown above depending on the size of the exhaust fan. Outside ambient air entering the room through this screened vent opening is not conditioned.
This unconditioned air becomes mixed with the conditioned air that is circulated by the indoor fan. Zoneline vent openings are not intended to be the source of make-up air for building ventilation systems due to the additional heating or cooling loads generated. Heat pump units with ICR are not available with corrosion protection and should not be installed in seacoast or corrosive environments. See page 34 for a discussion of the Internal Condensate Removal system available on Series heat pumps.
Moisture removal is an important function of an air conditioner. People are more comfortable at higher temperatures when the humidity level is relatively low.
Air conditioners operate with less energy consumption when the room temperatures are set higher. Customers who are using the Dry Air 25 report a freshersmelling room as a result of the lower humidity levels, as well as lower operating costs.
RAK — A door with a lock that replaces the standard control cover door to prevent unauthorized changing of control setting is offered as an accessory. The auxiliary control push button is located behind the room cabinet, below the control panel. The auxiliary controls come preset to the modes most desired by customers. However, the owner is responsible for ensuring the auxiliary controls are set to the desired function.
There are 9 different modes that can be set using the auxiliary set button. When Freeze Sentinel is activated, it automatically provides heat without user interface. When Heat Sentinel is activated, it automatically provides cooling without user interface. Mode 5— Temperature Limiting. This setting is used when the unit is installed using a duct adapter kit. If the unit is ducted, the Duct Mode needs to be set to ON. This increases the fan speed to ensure proper circulation.
This electric heat option functions only on the model. When this option is ON, heat pump operation is locked out, causing the unit to provide only electric resistance heat. Mode 9— Heat Boost AZ only. The default setting for Mode 9 is OFF. This setting is used to provide supplementary heat to the heat pump operation by electric resistance heat in conditions where the heat pump-only operation is not sufficient to maintain a consistent, comfortable room temperature.
Temperature Boost option should not be used with remote thermostat operation. Some installations may want to govern the ability of the unit to operate from a control device remote to the unit or even remote to the room in which the unit is located. The general term given to systems such as this is Central Desk Control. The most common installation of this type of system is a switch mounted at the registration desk and, upon guest check-in, a button is pushed or a switch is moved to allow the air conditioner to operate.
It is not necessary that the controlling device be located at a central desk to employ a device that will control the unit operation. For instance, in some resort areas devices are connected to sliding glass doors and opening the door causes a contact to close, turning the air conditioner off.
This prevents energy being wasted by operating the air conditioner when warm, humid air is entering the room. Some systems operate by motion sensors or heat-sensing detectors mounted in the room. These types of systems determine occupant presence in the room and allow the unit to operate; if no one is in the room the device signals the air conditioner to turn off.
There is a wide variety of devices available, each with its own benefits and constraints. While GE does not offer. Consult with the provider of the energy management system to be sure it is compatible with GE Zoneline units. Zoneline units have standard connectors factory-installed to provide a CDC interface that permits the unit to be connected to most of the energy management systems.
The devices connected. When the switching device closes the circuit of the CDC conductors, the unit operation stops. Do not use a common bus at the unit or at the switch panel in the wiring. Both wires comprising the circuit must connect to the unit connectors and to the controlling switch. Running one wire from one unit to another unit is common busing and may damage internal components or cause erratic operation of the system.
A volt transformer is contained within the Zoneline unit. No external voltage may be applied to the unit through the CDC terminals. Voltage on the CDC conductors is. Recommended wire size must be followed as a minimum requirement. Connecting the Zoneline unit to a CDC system does not eliminate the ability to connect the unit to a remote thermostat. Please see page 55 for installation recommendations for the Central Desk Control wiring. In some installations, control of the operation of the unit at a location remote from the unit itself may be desired.
A unit mounted high in the wall or over a door, for instance, where. Other installations may use remote thermostat control for design or performance enhancement.
The unit is connected to the thermostat by low-voltage wiring which permits the operation of the unit to be selected and the temperature sensed at the thermostat. Important Notes: Remote thermostat wiring should not be run through wall case. Thermostat wiring should exit the wall below the unit and enter the unit between room cabinet and chassis.
Wire molding may be used to hide thermostat wiring. If a sub-base is used, the thermostat wiring may be concealed by the sub-base. Thermostat wiring should not be run parallel to line voltage wires since induced current may cause erratic operation. All Zoneline and Series units are adaptable to Class 2 remote low-voltage thermostat.
The only additional fieldsupplied components are the remote thermostat and wiring necessary to connect it. The controls on the unit are not functional when the remote control function is used. The Zoneline resistance heat units may be connected to a single-stage thermostat designed for use with cooling with electric heat systems.
GE offers two thermostats compatible with the Series unit. The remote thermostat-Class 2 option Mode 6 in the auxiliary control setting must be turned ON to enable remote thermostat control. Refer to installation instructions packaged with the chassis.
Please see page 55 for installation recommendations for the remote thermostat wiring. Compatibility of other thermostats considered for use with GE Zoneline units is the responsibility of the customer. The control voltage on the remote control conductors is 24 volts AC. The AC voltage may not be compatible with some solid-state thermostats. The fan speed for the Series in remote thermostat operation is selected by the connection of the fan wire from the thermostat to either the HIGH or LOW terminal on the unit.
Operating the unit in low fan speed reduces the operating sound level of the unit. See page 14 for additional information on the CDC system. Unit temperature limiting settings are not functional when unit is connected to a remote thermostat. GE offers two thermostats compatible with the. Compatibility of other thermostats considered for use with the GE Zoneline unit is the responsibility of the customer.
When connected to a remote thermostat, the indoor-air- temperature sensing is shifted from the unit to the remote thermostat. For this reason, the units will operate slightly differently when connected to a remote thermostat. The above chart shows the unit operation when connected to a remote thermostat.
Unplug the unit or disconnect power and remove the room cover. Plug the unit back in or reconnect power. Press the Aux Set button once. The letters AU will appear in the display. Press the up arrow once so the top half of the right hand digit is lit.
Press the Aux Set button to exit the setup function. The units employ a logic system monitoring both outdoor and indoor temperatures to determine the heat source, thus increasing energy savings by operating longer in the heat pump mode. Heat pumps save energy and cost less to operate than units with electric resistance heaters as the only heat source.
Just as the EER of an air conditioner is an indication of the efficiency of the unit, COP Coefficient of Performance is the indication of the efficiency of the heat pump. This relative efficiency of a heat pump compares the unit to electric resistance heat.
If a unit has a COP of 3. The compressor is used in heat pump operation just as in air conditioning operation. In heat pump operation, the hot refrigerant gas is directed to the indoor coil rather than to the outdoor coil. Room air that circulates over the. As the outdoor temperature falls, the heat pump is able to extract less heat from the outdoor air to raise the temperature of the indoor air.
For this reason, all packaged terminal heat pumps also have electric resistance heaters as backup to heat pump operation. At some point, the heat pump is unable to provide sufficient heat to adequately warm the room. Many Packaged Terminal Heat Pumps cease heat pump operation and change to more expensive resistance heat at some pre-determined outdoor temperature to compensate for.
Virtually every room is unique—with different insulation, different sizes and types of windows, different types of construction, different directional exposures. All these variables, as well. For these reasons a consulting engineer should be engaged to calculate the heat loss and specify the heat pump unit required.
GE offers the series of Zoneline heat pump units—with highly featured microprocessor controls—react to the indoor temperature as well as the outdoor temperature in determining the heat source to provide comfortable room. This determination of the heat source based on the indoor temperature helps provide a more comfortable room.
