INSTALLATION AND OPERATION MANUAL
13
•
changing temperature only at the beginning of a particular range;
•
setting the same temperature but setting it earlier or later in order to change
duration of a given period;
•
changing the temperature and starting time of a range with the new temperature.
Repeating the settings at the same time the next day of the range updates the programs
with new times and / or temperatures.
The algorithm may allow not all of the changes. In such case the change should be
introduced manually in PROGRAMS menu.
When establishing a new range and when shifting its time limit, the RANGE TIME LIMIT
CHANGED information appears in the text box. When changing the temperature, the RANGE
TEMPERATURE CHANGED information appears. If both the time and the limit are changed,
then both pieces of information are displayed.
Learning may be turned off (item 306
–
NO) at any time without losing the stored ranges.
Please remember that reactivating learning deletes all stored ranges.
Irrespective of the learning mode, the ranges may be deleted, freely changed or added
manually in the PROGRAMS menu (item 2) at any time. Any manual temperature change
may be set at any time (see: II. User functions, point 3). Setting it once does not affect the
ranges established during learning.

HEATING IN ADVANCE

(see: Section II. User functions,
point 2d.)

heating a room in advance
The time of turning the heating in advance on is calculated with a sophisticated algorithm,
taking into account previous room heat-up times and currently measured temperature.
The thermostat needs several operating days to properly calculate times for various
temperatures, thus for the first days the calculated times may not be enough to achieve
precisely the preset temperatures at established times. Usually, the correct values are
reached within two, three days.
For a proper operation of the advance-heating algorithm, at least two temperatures varying
by minimum of 0.5ºC must be set in the thermostat.
The time of advance is calculated and updated in the thermostat memory even if heating in
advance is not switched on in the service menu (item 307). If the thermostat was already
operated in a place and then moved to another room (building), then the advance times
may vary from the required ones and will reach a stable value within several days. In
particular cases, it is recommended to delete the stored advance times. In order to do so,
switch off the advance function and then switch it on again.
After switching this function on, it is possible to select the mode of advance:
•
COMPLETE
–
switching the heating on with the exact calculated period of heating in
advance;
•
LIMITED
–
the calculated time of heating in advance may be shorter than the one set
with this item.
Time of advance may be limited within the range from 20 to 240 minutes. This ensures that
the heating will not start too early. However, in such case, heating the room up to the preset
level may be delayed. In special cases when the range in question is short, the preset
temperature may not be achieved at all. However, it will be higher than without advance.
8.
FROST PROTECTION
–
(item 308)
It maintains minimum temperature preventing freezing of the system. It is set within the
range from 1 to 10ºC. By default: 5ºC.
In case there are gaps between ranges when the protection is active, the frost protection
temperature will be implemented during these gaps.
