Heat Pumps and Energy Savings
• Heat Pump Operation — Zoneline 5200 Series
Heat sources: Heat pump, heat pump and simultaneous electric
resistance heat, or electric resistance heat
The Zoneline 5200 Series heat pumps employ a highly
featured microprocessor control system interfaced with
thermistors to accurately measure indoor air temperature,
outdoor air temperature, indoor coil temperature, and
outdoor coil temperature. This system allows the
microprocessor to precisely and predictably react to
changing conditions in order to provide a very advanced
Packaged Terminal Heat Pump operating system.
The Zoneline 5200 series is designed to help insure a
comfortable room. When “HEAT” is selected, the unit will
determine if the room air is warm enough to satisfy the
thermostat setting. If the temperature at the unit sensor is
below the desired temperature, the electric resistance heater
will be utilized to warm the room to the point where the
thermostat is satisfied. This feature is designed to allow the
temperature of an unoccupied room to be maintained at an
energy saving level without inconveniencing the room
occupant. Once the thermostat has been satisfied, the
resistance heater will turn off and the heat pump will
operate as shown in Zoneline 5200 Series Heat Source Logic
chart when the thermostat calls for heat again. The unit will
operate in this manner even if connected to a Central Desk
Control.

The “Temperature Boost” option, selected by a hidden dip
switch #8, utilizes the supplemental simultaneous heater
with heat pump operation when the outdoor temperature is
below 46°F. regardless of the indoor air temperature. The
chart above indicates the heat source of the Zoneline 5200
series heat pump under various indoor and outdoor
conditions. The unit is designed to provide heat pump
savings without sacrificing room comfort.
The Quick Heat Recovery feature is not affected by the
Zoneline 5200 Series Heat Source Logic shown in the chart
above. For more information about the Quick Heat
Recovery Feature, see page 14. The full heat output of the
resistance heater is dependent upon circuit amperage and
the power connection kit used. See pages 38 and 39 for
information on the power connection kits and available
heater capacities.
Heat pump defrost - 5200 Series
The Zoneline 5200 Series has a reverse cycle demand defrost
system to extend heat pump operation and increase savings
from the extended operation. The microprocessor
switch #8, utilizes the supplemental simultaneous heater
with heat pump operation when the outdoor temperature is
below 46°F. regardless of the indoor air temperature. The

Heat pump defrost - 5200 Series
The Zoneline 5200 Series has a reverse cycle demand defrost
system to extend heat pump operation and increase savings
from the extended operation. The microprocessor
determines the need for defrosting by criteria based on
continuous compressor running time, outdoor air
temperature, outdoor coil temperature, and the rate of
temperature change of the outdoor coil. When defrosting is
required, the unit reverses the flow of refrigerant to direct the
hot gas into the outdoor coil to melt the frost build-up.
Before and after actual reverse cycle defrosting, the unit shuts
off the compressor to allow the refrigerant pressures to
equalize throughout the system. This eliminates the
possibility of a loud reversing noise. During these periods of
pressure equalization, the full resistance heat capacity of the
unit is activated to help insure room comfort conditions
during the defrost cycle. The defrost cycle termination
requires a minimum of 2 minutes and a maximum of 9
minutes or an outdoor coil temperature of 68°F.
Heat pump condensate See page 32 for information on heat
pump condensate. The Zoneline 5200 Series heat pump may
be ordered with a factory installed Internal Condensate
Removal (ICR) system to minimize the amount of
condensate water draining from the unit during heat pump
operation.

Optional Interface Module —
RAKOIM
RAKOIM
The RAKOIM is required if a unit is to be installed with a
Central Desk Control or Remote Thermostat.
The RAKOIM is installed under the control box. There are
channels to contain the RAKOIM and screws are provided to
secure it in place. There is a short wire harness on the
RAKOIM that is plugged into the mating receptacle on the
front of the control box just below the dip switches. There are
screw terminals on the front of the RAKOIM for field wiring.
Follow the instructions included with the RAKOIM when
installing this accessory.
