A. Capacitors
The capacitors are used to temporarily boost
the power output available to the fan motor
and the compressor at start-up. The specifi-
cations of each capacitor are listed on the
left.
B. Relay Board
The relay board receives signals and outputs
from the control board that contains a micro-
processor. The relay board contains the
compressor, fan on and fan mode (speed)
relays. It also contains a step-down trans-
former that converts the line voltage (115
VAC) to 12 volts. This is then converted from
AC to DC and used for relay coil activation.
The 12V (DC) power is sent to the Control
Panel Assembly where it is further regulated
to 5 volts for the system logic.
The relay board also contains the DIP-Switch.
The DIP-Switch is used to change the Fan
Mode operation from Stop to Operate and
change the temperature display from ˚F to ˚C.
NOTE: The relay board must be serviced as a
complete assembly. It has only one serviceable
component, the fuse.
(a) Relay Board Fuse
NOTE: The relay board fuse is the only serviceable
component on the relay board assembly.
This fuse provides protection against damage
to the step-down transformer. It must be
replaced with the exact type of fuse or an
equivalent.
Fuse Specifications: 160mA / 250V

CAUTION: Failure to use the exact type of fuse
could result in damage to the unit and/or to
components. It will also void the warranty of the
unit.
