CONTROL OPERATION

NOTE: Screenshots shown in this manual reflect
default settings (when applicable).

On/Off Control

The wall-mount unit can be turned on and off with the
TEC-EYE. When the unit is set to ON, the system will
heat and cool the space either in orphan mode or when
connected to the LC. When the unit is set to OFF, the
unit will not heat or cool the space.
To turn the unit on or off:
1. Press MENU key to go to the Main Menu screen.
2. Press UP or DOWN keys and ENTER key to enter
USER password 2000.
3. Press UP or DOWN keys to scroll to ON/OFF; press
ENTER key.
4. Press UP or DOWN key to change the system from
OFF to ON or from ON to OFF.
5. Press ESCAPE key until Main Menu screen is
displayed.

Blower Control

The blower will be in continuous operation in orphan
mode. To operate the blower continuously while
communicating with the LC6000 or PGD stand-alone
display, refer to the latest version of the 2100-669
LC6000 Service Instructions manual or 2100-678
th-Tune manual.
The 11EER MULTI-TEC wall-mount unit is equipped with
an ECM 5-speed blower. Three different speeds are used:
Low for Balanced Climate, nominal for normal blower
operation and high for high sensible (see Figure 19).
FIGURE 19
Blower Speeds
Blower Speed 1: Balanced Climate (NO7)
This blower speed is available when the unit is in passive
dehumidification and there is a cooling or heating call.
Manual 2100-725C
Page 14 of 39
Blower Speed 2: Nominal (N08)
This blower speed is available when the unit is in
cooling, heating, orphan mode, freeze condition, free
cool or continuous blower.
Blower Speed 3: High Sensible (N09)
This blower speed is available when the unit is in high
sensible mode, which is selectable from the LC6000
controller, and cooling mode is active.
The Balanced Climate (blower speed 1) and high
sensible (blower speed 3) are only available when
connected to the LC6000 controller.
IMPORTANT: If the unit model number does not have
the letter C as the fifth character (Ex. W36ACP...), the
blower will not run in orphan mode.

Balanced Climate Mode

MULTI-TEC Series wall-mount units offer an enhanced
latent capacity that can be controlled by an LC6000
controller. When passive dehumidification (Balanced
Climate mode) is active on the LC6000 controller, the
unit will increase the amount of moisture removed
during compressor operation. When high sensible
mode is enabled on the LC6000 controller, this mode
increases the sensible cooling capacity to increase
the amount of heat removed from the structure during
compressor operation.

Balanced Climate Enable/Disable

When the MULTI-TEC is connected to an LC6000
controller, Balanced Climate mode can be enabled or
disabled. Balanced Climate mode is disabled by default.
To enable or disable Balanced Climate mode:
1. Press MENU key to access the Main Menu Screen.
2. Press UP or DOWN keys and ENTER key to enter
USER password 2000.
3. Press UP or DOWN keys to scroll to Adv Sys Config;
press ENTER key.
4. Press UP or DOWN keys to scroll to Blower Settings
(B5)
5. Press UP or DOWN keys to scroll to Balanced
Climate (see Figure 20).
6. Press UP or DOWN keys to adjust value.
7. Press ENTER key to save.
