“Room controller” wired control

Power up

All segments of the LCD should be energized for five seconds. The mode, fan, louver, desired temperature and configuration information should be read from the EEPROM.

If the EEPROM values are not valid, the following should be used as defaults.

Operating Mode

= AUTO

Fan Speed

= AUTO

Desired Temperature

= 72°F

°F o °C

= F

Louver

= AUTO

Room Thermistor Override

= OFF

Cooling only vs Heat/Cool Remote = Heat/Cool

Example of normal operation

When switched on, the control display appears.

Setting mode operation

“MODE” button

Pressing the “MODE” button will cause the mode to change. The “MODE” button must be released and then pressed again in order to change to the next mode.

The active mode will always be lit in normal operation. Available modes to select are:

Heat/Cool Remote:

OFF, COOL, DRY, FAN ONLY, AUTO, HEAT

Cooling Only Remote:

OFF, COOL, DRY and FAN ONLY

When the “MODE” button is not pressed for 15 seconds, the next press will always switch the mode to OFF.

OFF Mode:

ICONS Energized:

•OFF Mode

•Room Temperature if configured for Room Thermistor Override, otherwise nothing

Buttons available:

•“MODE” button

AUTO, HEAT, COOL and DRY Modes:

ICONS Energized:

•Operation Mode ICON.

•Room Temperature if configured for Room Thermistor Override (operated by Room Controller), otherwise user selected temperature with the “SET TEMP” Icon.

•FAN/LOUVER Icon with the user selected Fan and Louver settings.

Buttons available:

•All Buttons are available.

AUTO Automatic operation

NOTE:

The compressor and electric heater must be off for at least 30 Minutes, this time being necessary to pass from Heating to Cooling, or Cooling to Heating.

This will prevent the system from switching between Heating and Cooling continuously.

COOL Cooling operation

DRY Drying operation.

HEAT Heating operation.
