The 7-day program offers different switching patterns for every day of the week. This
means that one of the three 24-hour switching patterns can be selected differently for
every day of the week, depending on the requirements. Like with the 24-hour program,
time and setpoint of every switching point can be different.
In the automatic modes, a manual change from normal to economy temperature can be
enforced via the override button. The selection will automatically be reset when the next
switching point is reached or when changing the operating mode.
If the temperature displayed does not agree with the room temperature effectively
measured, the temperature sensor can be recalibrated.
Calibration is activated with DIP switch no. 9 (sensor calibration ON) and a DIP switch
reset. The displayed room temperature can be brought in line with the room
temperature effectively measured, the increments being 0.2 °C (max. ±2 °C).
When sensor calibration is completed, the DIP switch must be reset to OFF and the
DIP switch reset button must be pressed.
Switch-on point P.1, which is the first switch-on point of the day, is brought forward
such that the selected sepoint will be reached at the desired time.
The setting depends on the type of control system in use, that is, on heat transmission
(piping system, radiators), building dynamics (building mass, type of insulation), and
heating output (boiler capacity, flow temperature).
Optimization can be set with DIP switches no. 6, 7 and 8.
