In automatic operating modes, the temperature setpoints can be individually adjusted
for every comfort period and for the continuous operating modes. The temperature
setpoint of economy mode is the same in automatic and continuous operation.
In frost or overtemperature protection mode, the room temperature is constantly moni-
tored. If it falls (rises) below (above) the adjusted setpoint, control to the adjusted frost
or overtemperature protection setpoint
The "special" day is a 24-hour exception mode with one heating or cooling phase. The
switch-on and switch-off time and the setpoint for the (heating or cooling) phase are set
manually.
The settings for the "special" day (exception) are not linked to any particular day, and
remain in memory until you modify these settings yourself. You can then select this
preset special day operating mode quickly and easily with the operating-mode selector
button . It will remain active until another operating mode is selected.
The switching program can be used as a 7-day or 24-hour program, depending on
programming. It is also possible to select one of the continuous operating modes
with which the switching program is not used.
With the 7-day program, all individual days, working days (1-5), weekend (6-7), or the
entire week (1-7) can be programmed.
For each heating / cooling period, 3 different switching patterns are available.
There is a choice of 1, 2 or 3 heating / cooling periods. For each heating / cooling pe-
riod, the start time, end time and comfort setpoint are to be entered.
In between heating / cooling periods, the same economy temperature setpoint is al-
ways used. This economy temperature setpoint can be adjusted on the temperature
menu.
