WARNING:
Turn off electric power
at the fuse box or service panel before making
any electrical connections� Also, the ground
connection must be completed before making line
voltage connections� Failure to do so can result in
electrical shock, severe personal injury, or death�
Time Delay Control (TDC)
The time delay (TDC) is in the low voltage control
circuit� When the compressor shuts off due to a
power failure or thermostat operation, this control
keeps it off at least 5 minutes which allows the
system pressure to equalize, thus not damaging
the compressor or blowing fuses on start-up�
Remote Outdoor
Temperature Model
(Part No. 47-102709-03)
This is a kit that has a longer remote sensor that
can be installed away from the outdoor unit for
better thermostat temperature display�
Heat Pump Thermostat
Warning Light Kit RXPX-D01
This component senses a compressor lock out
and tells the thermostat service light to come on�
This will let the homeowner know that service is
needed on the system�
NOTE:
Warning light on thermostat will come on
during a 5 minute compressor time delay and for
5 seconds during defrost while the compressor is
off� Homeowner should only be concerned if light
stays on for more than 5 minutes�
Low Ambient Control (LAC)
(Part No. RXAD-A08)
This component senses compressor head
pressure and shuts the heat pump fan off when
the head pressure drops to approximately 250
PSIG� This allows the unit to build a sufficient head
pressure at lower outdoor ambient (down to 0°F
[-18°C]) in order to maintain system balance and
obtain improved capacity� Low ambient control
should be used on all equipment operated below
70°F [21°C} ambient�
