6.3.1 Manual Adjustment
Use this adjustment mode to set the temperature manually. To place
the controller in this mode, press Auto/Man so that disappears
from the screen and set the temperature using the buttons.
NOTE: If the controller is in automatic heat/cool changeover, the setpoint is
automatically lowered or raised by 1°C (2°F) when the controller switches to
heating mode or to cooling mode respectively. For example, if you place the
setpoint at 24°C (75°F) while in heating mode, the setpoint will become 25°C
(77°F) in cooling mode and will return to 24°C (75°F) when the controller
switches back to heating mode.
6.3.2 Automatic Adjustment
Use this adjustment mode if you want the controller to automatically
adjust the temperature according to the programmed schedule. To
place the controller in this mode, press Auto/Man so that
appears on the screen.
Pre-programmed Schedule
The following schedule has been programmed at the factory. Two
temperature settings are programmed for each period of the sched-
ule: one is used in heating mode and the other in cooling mode.
NOTE: When programming the heating setpoint, it cannot be higher than
1°C (2°F) below the cooling setpoint. For example, if the cooling setpoint is
25°C (77°F), the highest you can place the heating setpoint is 24°C (75°F).
Conversely, when programming the cooling setpoint, it cannot be lower than
1°C (2°F) above than the heating setpoint.
Modifying the Schedule
You can program up to 4 periods per day. For each period, you can
set the start time, the heating mode setpoint and the cooling mode
setpoint. The program can be different for each day of the week.
•Press Pgm to enter the programming mode. The settings for
Monday, Period 1 (P1) appear.
• To select a day to program, press Day until the day is dis-
played. Press Day for 3 seconds to select all 7 days.
NOTE: If you select all 7 days, the settings of the displayed period will
be copied to all 7 days. For example, if period 1 is displayed and you
then select all 7 days , they will all now have the same settings for
period 1. If you display period 2 while all 7 days are selected, they will
all now have the same settings for period 2.
• To set the start time of a period, first press Pgm until the period
number (P1 to P4) is displayed and the time display flashes.
Then press the buttons. The time changes in increments of
15 minutes.
NOTE: During programming, to skip a period press Clr while the period
is selected. For example, in the pre-programmed schedule, periods 2
and 3 have been skipped for Saturday and Sunday.
• To set the temperature for a period, first press Pgm until the
period number (P1 to P4) is displayed and the temperature dis-
play flashes. Then press Mode to select the heating mode set-
point display or the cooling mode setpoint. Finally press the
buttons.
• Press to exit.
The following diagram shows how to navigate the programming
menu.
Temporary Bypass
When you modify the temperature setpoint while the controller is in
automatic mode, the new temperature is used for the next 2 hours.
The icon flashes during the bypass. After the bypass, the
temperature set for the current period is used.
The controller can be placed in unoccupied mode via a remote con-
trol device such as Aube’s CT241 telephone controller (see section
2.10). In this mode, the setpoint is set back by 4.5°C (8°F); it is low-
ered in heating mode or raised in cooling mode. The message UNOC
appears during the unoccupied mode.
NOTE: Automatic changeover is disabled during the unoccupied
mode.
Temporary Bypass
In unoccupied mode, only the buttons work. When you adjust
the temperature during this mode, the new temperature will be used
for the next 2 hours, after which the controller will return to the previ-
ous setpoint. The message UNOC flashes during the bypass.
