Programming the clock and timers

The clock must be set before the timers will operate. The temperature setting during timer operation is the temperature last used when the appliance was on.

During the steps below, if no button is pressed for 90 seconds then the screen will return to the current time display.

1. Press the TIME SET button. The display will show the words “Clock Set” and “AM 12:00” or the time.

2. Use the UP or DOWN buttons to set the desired clock time.

NOTE: If you do not want to set the timers now then press the TIME SET button five more times to finish setting the clock.

3.Press the TIME SET button. “Timer 1 Set ON” and “AM 6:00” or the last programmed time

will be displayed. Use the UP or DOWN buttons to set the desired on time. When finished press the TIME SET button.

4. “Timer 1 Set OFF” and “AM 9:00” or the last programmed time will be displayed. Use the UP or DOWN buttons to set the desired off time. When finished press the TIME SET button.

5. To set Timer 2 repeat steps 3 and 4. If finished press the TIME SET button two more times to complete setting the clock

One or both timers can be used. To allow Timer 1 the appliance to operate during the pre-

programmed times press the TIMER 1 and/ or TIMER 2 button. The display will briefly show the “on” and “off” times for each timer.

Timer 2 If the current time is outside of the programmed times then the appliance will

go into standby mode and the Timer Indicator will glow green.

To turn the timers off press the appropriate timer button again. If the appliance was on, it will return to standby mode and the Operation Indicator will glow green.

The Timer Indicator will not display if both timers are turned off.

Using the Override

This function is used to manually override Override Timer programmed operation.

If the appliance is operating in Timer mode then pressing OVERRIDE will turn the

it OFF and cause the

Time word “Override” to be displayed for 10 seconds.

If the appliance is in Timer mode but outside of the programmed time

for operation then pressing OVERRIDE will turn the appliance ON.

OVERRIDE does not change the programmed times.

Pre-heat

The appliance may operate up to one hour before the programmed ON time in order to allow the room to reach the desired temperature by the programmed ON time. The pre-heat time (how long before the programmed ON time that the appliance will provide heat) is determined by the difference between the temperature setting and the room temperature one hour before the programmed ON time.
