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.
