Select the economy temperature
and press the time button, then enter the num-
ber of days you are absent
(max. 99 days). The display will show the num-
ber of days and the holiday symbol. Every midnight, the counter subtracts one day.
When the day counter reaches 00, the 24-hour operation with two heating phases will
automatically be resumed.
Press the day counter and set it to 00.
If the temperature displayed does not agree with the room temperature effectively
measured, the temperature sensor can be re-calibrated. For that purpose, set the DIP
switch for Sensor Alignment to ON and press the DIP switch button.
Press
to bring the flashing room temperature in line with the room temperature
currently measured. The increments for the readjustment are 0.2°C {max. ±2 °C).
When balancing of the sensor is completed, the DIP switch must be reset to OFF.
Before cleaning the display or to prevent tampering, the display buttons can be locked.
Press the button behind the little hole for a short moment (max. 1 second):
ap-
pears and all other displays disappear. The display buttons are now disabled while all
the other functions are fully maintained.
Press the button behind the little hole again (max. 1 second).
Keep the button behind the little hole depressed for at least 3 seconds. This resets the
individual settings and the time of day to their default values. During the reset time of 3
seconds, the display will be fully lit, allowing the proper functioning of the display to be
checked. After each reset, all personal settings such as time of day, weekday, switch-
ing points, temperature setpoints, sensor calibration, etc., must be re-entered.
About three months before the batteries are exhausted, the display shows the battery
symbol
. The other displays disappear, the display buttons are deactivated while
all the other functions are fully maintained. When changing the batteries, the current
data will remain stored for at least one minute.
Using a suitable remote operating unit, the REV100 can be switched to economy mode
. Changeover takes place by closing a
SRWHQWLDOIUHHFRQWDFW
connected to terminals
T1 and T2. In that case, symbol
appears on the display. When the contact opens,
the selected operating mode will be reactivated.
