Programming button -D-
By pressing this button (in
Normal mode) it will enter Programming mode, which enables the selection
of one of the following options:
-2-
Programming of the set temperatures for heat and cold in
Occupied, Comfort or Day sta‐
tus.
-3-
Programming of the set temperatures for heat and cold in
Standby, Economy or Night
status.
-4-
Programming of the set temperatures for heat and cold in
Unoccupied status.
-7-
Setting of the clock (day of the week, hours and minutes).
-16-
Programming of the time profiles. A time profile only permits
Comfort and Economy (Day
and Night) status.
-19-
Fan programming.
Occupancy status button -E-
By pressing this button (in
Normal mode) the current occupancy or comfort (Day / Night) status changes
and the set temperature is displayed next to the flashing icon -8-. If you press the button again whilst still
in
Adjustment mode, it will switch from one status to another in a sequential and cyclical manner.
If button -E- remains pressed down for more than one second, it switches to
Unoccupied mode. If no
other action is taken in this mode, the unoccupied status will remain indefinitely.
If button -D- is pressed, the setting disappears and the no. 0 is displayed in its place to indicate the
number of days for which the unoccupied status must last. Buttons -F- and -G- increase or decrease the
days during which the status is to be unoccupied (with a maximum of 99 days). Icon -7- is displayed.
More -F- and less -G- buttons.
By pressing one of the two buttons (in
Normal mode) it will switch to Adjustment mode, displaying the
current temperature setting, which is indicated by the flashing icon -8-.
If it remains pressed down for more than one second or it is released and then pressed again whilst still
in
Adjustment mode, the temperature setting will be increased by 0.5 °C or 1 °F.
If the two button are pressed at the same time, it switches from °C to °F and vice versa.
2.2 Economiser, modulating, temperature control
This consists of one damper located on the unit return and another located on the outdoor air inlet.
The control compares the outdoor air and return air temperature values and sets the opening of both
dampers proportionally using the 0 ‑ 10 V modulating actuator with return spring.
To guarantee a good comfort level, the supply temperature is limited to 12 °C.
The dampers are factory-set for a minimum volume of outdoor air of approximately 10%.
The outdoor air damper has rain protection, which is supplied separately, ready for installation on the
outdoor air inlet opening on the side of the unit.
Where necessary, enthalpy probe control options can be added to the economiser (see section
Enthalpy
probes
, see on page 44) as well as an exhaust system for excess air when the design of the installation
requires as such (see sections
Barometric excess pressure damper
, see on page 44 and
Exhaust
fan
, see on page 45).
