APPLICATION DATA (cont)
13. Controls
a. Wired 24-v controls (619C, 619F)
1) A 24-v thermostat is supplied for operation of all in-
ceiling and cassette systems.
2) Controller can only operate one unit, and a controller
is required for each unit.
3) The control must be located in the space being con-
ditioned.
b. Wireless remote controller (619E)
1) A wireless remote controller is supplied for system
operation of all high wall units.
2) Each battery-operated wireless (infrared) remote
controller may be used to control more than one unit.
3) The wireless remote controller has a range of 20 ft.
4) The unit is equipped with an emergency switch
which allows operation if the remote controller mal-
functions or is misplaced.
5) Because the controller uses infrared communication,
all of the following must be true for the controller to
work properly:
• The power must be on to the fan coil unit.
• The batteries in the controller must be good.
• The controller must be within range of and pointed di-
rectly at the unit.
• The unit’s 3-position switch must be set in the Remote
position.
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 duct-free split systems provide 24 v power for the out-
door unit from the indoor unit except the 619E009 and 012
systems, which provide line voltage control.
All other fan coil types should have a separate disconnect
for indoor and outdoor units.
15. Air throw

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 cfm. Air quan-
tities above this level may exceed compressor maxi-
mum saturated suction temperatures. A power
ventilation kit is available to overcome ventilation duct
static. See Power Ventilation Kit Available Static Pres-
sure 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 47.

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.
