If economy mode has been set in the system, the work setting will
be varied dynamically based on the actual system demand; this
demand is calculated by checking the status of each thermostat
each given time interval and this parameter allows to specify this
interval (it can be between 5 and 60 minutes); to set this value
it is necessary to:
(1) Enter modifi cation mode by pressing the
C
key; after
this key has been pressed, the current band value will be
highlighted.
(2) Press the
A
or
B
key to modify the band value to be
applied to the heating work setting during Economy mode.
(3) Press the
C
key to confi rm the value entered; once this
key has been pressed, the current setting will be highlighted
normally, thus indicating that the modifi cation procedure has
concluded.
After the data has been entered, it will be possible to:
- Pass on to the following window by pressing the
B
key.
- Go back to the previous window by pressing the
A
key.
- Press the
D
key to return to the selection of the menus.
• Set frequency for dynamic variation of setting in ECONOMY mode
The proposed example hypothesises that
thermostats are controlled to vary the
setting in Economy mode once every 5
minutes.
If economy mode has been set in the system, the work setting
will be varied dynamically based on the actual system demand;
this variation is performed every given amount of time, modifying
the setting by increasing it or decreasing it by a certain value
(while remaining within the limits described by the bands set
for Economy mode in heating and cooling); this parameter
determines by how much the work setting is decreased if the
control on the system requires it (value between 0.1 and 2.0°C);
to set this value it is necessary to:
(1) Enter modifi cation mode by pressing the
C
key; after
this key has been pressed, the current band value will be
highlighted.
(2) Press the
A
or
B
key to modify the band value to be
applied to the heating work setting during Economy mode.
(3) Press the
C
key to confi rm the value entered; once this
key has been pressed, the current setting will be highlighted
normally, thus indicating that the modifi cation procedure has
concluded.
After the data has been entered, it will be possible to:
- Pass on to the following window by pressing the
B
key.
- Go back to the previous window by pressing the
A
key.
- Press the
D
key to return to the selection of the menus.
• Set the extent for decrease of setting in ECONOMY mode
The proposed example hypothesises that
the automatic decrease (if necessary) at
each control during Economy mode is
0.5°C.
