APPLICATION DATA (cont)
Wireless remote controllers (619E)
a. A wireless remote controllers is supplied for system op-
eration of all high wall units.
b. Each battery-operated wireless remote controller (infra-
red) may be used to control more than one unit.
c. The wireless remote controller has a range of 20 ft
minimum.
d. The unit is equipped with an emergency switch which al-
lows operation if the remote controller malfunctions or is
misplaced.
e. Because the controller uses infrared communication, all
of the following must be true for the controller to work
properly:
1) The power to the fan coil unit must be on.
2) The batteries in the controller must be changed.
3) The controller must be within range of and pointed
directly at the unit.
4) The unit’s 3-position switch must be set in the remote
position.
12. Group control
The 619C and 619F fan coil units may be group controlled
from a single timeclock or energy management system by
interrupting the 24-v power to the control board. See sys-
tem wiring books for details.
13. Thermistor
The 538S unit has one thermistor that monitors entering-air
temperature at the condensing unit. The 619E unit has 2
different thermistors mounted at the indoor unit. The indoor
unit thermistors are not monitored at the 538S outdoor unit.
14. Wiring
Use only copper wires from the disconnect to the unit ter-
minal block. Aluminum and copper-clad aluminum wires are
not acceptable.
All multi-split systems provide 24-v power for the outdoor
unit in the fan coil unit.
All systems should have a separate disconnect for each in-
door and outdoor unit.
15. Air throw
Refer to Air Throw Data table below for system air throw
capabilities.

NOTE: Air throw is with unit mounted with typical clearances in a 10-ft
high room.
16. Fresh air/ducting
a. The 619C ceiling-suspended fan coil units may bring in
up to 30% fresh air. The percentage of air allowable is
calculated based on the unit high speed airflow. Air
quantities above this level may exceed compressor
maximum saturated suction temperatures. A power ven-
tilation kit is available to overcome ventilation duct static.
See Power Ventilation Kit Available Static table below.
b. The 619F in-ceiling cassette fan coil units may bring in
up to 10% fresh air. This 10% maximum should not be
exceeded. A power ventilation kit is available to over-
come ventilation duct static. See Power Ventilation Kit
Available Static table below.
c. The 619F in-ceiling cassette fan coil units may have an
extension duct installed. See Static Capability and
Design Considerations figures on page 42.

SONE — A subjective unit of loudness, equal to the loudness of a pure tone having a frequency of
1,000 Hz at 40 decibels above the listener’s threshold of audibility. This is for comparative
purposes only.
