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.
