Aube Technologies Programmable H/C Controller TH146-P-U - Manual (Page 10)

TH146-P-U 10/12
The controller normally displays the measured indoor temperature.
To view the setpoint, press one of the
buttons. The setpoint and
the symbol will be displayed for the next 5 seconds.
Use this mode to set the temperature manually. To place the con-
troller in this mode, press Auto/Man so that disappears from the
screen. Set the temperature using the
buttons.
NOTE: If the controller is in automatic heat/cool changeover (see
section 6.2), the setpoint is automatically reduced or raised by 1°C
(1.8°F) when the controller switches to heating mode or to cooling
mode respectively. For example, if the setpoint is 24°C (75°F) in
heating mode, it 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.
Use this mode if you want the controller to 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: a heating setpoint and a cooling setpoint.
Modifying the Schedule
You can program up to 4 periods per day. To program a period, you
need to set the start time, the heating setpoint and the cooling set-
point. 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 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 you select all
7 days while period 1 is displayed, 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, 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: To skip a period, display the period and press Clr. For
example, in the pre-programmed schedule, periods 2 and 3
have been skipped for Saturday and Sunday.
• To set the temperatures for a period, press Pgm until the period
number (P1 to P4) is displayed and the temperature display
flashes. If necessary, press Mode to display the heating set-
point or the cooling setpoint. Press the
buttons to set the
temperature.
NOTE: The cooling setpoint is always higher than the heating set-
point by a minimum of 1°C (1.8°F). For example, if the cooling set-
point is 22°C (72°F) and you set the heating setpoint to 23°C (73°F),
the cooling setpoint will automatically become 24°C (75°F). How-
ever, if you raise the heating setpoint to 21°C (70°F), the cooling
setpoint will remain at 22°C (72°F). The same principle applies
when you set the cooling temperature.
• 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 temper-
ature set for the current period is used.
