Movincool CLASSICPLUS14 サービスマニュアル

Operation Section

22

• There are two basic components used to control the operation of the Classic Plus 14 electrical

system:

- Control panel assembly

- Control box

• The control panel assembly contains the control panel, control board (with inputs for the freeze

and room temperature thermistors), drain switch and a microprocessor.

• When the FAN MODE button on the control panel is pressed, the microprocessor turns on “FAN

HI” “COOL OFF” indication of LCD and activates both the fan on relay and fan mode relay. This

sends line voltage (115 VAC) from the fan on relay to the N.O. (normally open) contacts of the

fan mode relay. This output is connected to the J6 terminal (relay board) where the high speed

wire of the fan motor is connected.

• When this button is pressed again, fan turns to low mode (see below). Press again, fan stops.

• When the FAN MODE button on the control panel is pressed again, the microprocessor turns on

“FAN LO” “COOL OFF” indication of LCD and activates both the fan on relay and fan mode relay.

This sends line voltage (115 VAC) from the fan on relay to the N.C. (normally closed) contacts

of the fan mode relay. This output is connected to the J5 terminal (relay board) where the low

speed wire of the fan motor is connected.

• When this button is pressed again, fan stops.

• In addition to fan mode (as described above), when the COOL ON/OFF button on the control

panel is pressed, the microprocessor turns on “COOL ON” indication of LCD and if the

temperature set point is less than the current room temperature, activates the compressor relay

(relay board) after 120 sec delay. This sends line voltage (115 VAC) to the J4 terminal (relay

board) where compressor wire is connected. Then compressor turns on for Cooling Operation.
