About the controls on your Zoneline.

Controls

Temp Control
The temp control is used to maintain the room temperature. The
compressor will cycle on and off to keep the room at the same level
of comfort.
Press the + pad to raise the temperature.
Press the - pad to lower the temperature.
NOTE: The display shows the set temperature, not the room
temperature.
Fan, Mode and Operation Control
Sets the fan operation for HIGH or LOW.
For cooling
For fan-only operation
For heating
Turns the unit off. Power remains connected to the
Zoneline. The Freeze/Heat Sentinel features still function if
active. See the Freeze/Heat Sentinel section on page 6.
NOTE: The temperature display will flash if the control panel is locked
(see Control Lock Out section).
This LED will light up when the unit is
controlled by a wall thermostat. See page 7 for details.
NOTE: When switching between modes, it may take several minutes
to completely change operation.
About Your Heat Pump (AZ65 only)
Heat pumps can save money by removing heat from the outside
releasing that heat indoors.
To get the best performance from your heat pump, don't
change the room thermostat very often. Raising the heat setting
2–3 degrees will cause the Zoneline to use its electric heating
elements in order to reach the new temperature setting quickly.
Quick Heat Recovery
Activates each time the thermostat is switched from OFF or COOL
mode to HEAT mode. Electric heaters are energized until the
thermostat set point is reached. On heat pump models, the heat
pump operation will resume at the next call for heat.
Control Lock Out
The control panel can be locked out to prevent users from changing
the operation mode of the unit.
While the unit is in the desired operating mode, press and hold the
DISPLAY SHOW/HIDE button for 10 seconds to lock the control and
the desired setting. Any key press after that will result in the mode
LED and temperature that was locked ot flash 5 times and then go
dormat.
To unlock the control lock out feature, press the DISPLAY SHOW/HIDE
button for 10 seconds to unlock and resume normal operation.
There is a 3-minute minimum compressor run time at any setting
to prevent short cycling.
The fans start before the compressor and stop after the
compressor cycles off.
When the outdoor temperature is lower than 25°F, heat is
provided by the electric heater instead of by the heat pump.
The electric heating elements use much more electricity than
heat pumps and cost more to operate.
