9. Operating setpoint, ECONOMY/BOOST, HOLIDAY MODES
If one of the digital contacts is configured as a “non-occupied/holiday” remote contact
015
=3 (DI1) or
017
=3 (DI2) or an ana-
logue input is configured as a “non-occupied/holiday” contact
019
=10 (AI1) or
021
=10 (AI3) or
023
=10 (AI3) the “non-occupied/
holiday” mode can be activated if the corresponding contact is in the appropriate position (see “36. Digital and analogue input
logic” page 126 ).
2-pipe systems (
014
= 0, 1):
In the “non-occupied/holiday” mode, the heating setpoint is decreased by 121 (see the 2-pipe heating graph, WHS ), the
cooling setpoint is increased by
121
(see the 2-pipe cooling graph, WCS ).
4-pipe systems (
014
=2,
3, 4):
In the “non-occupied/holiday” mode, the heating activation point is decreased by 121 (see 4-pipe graph,
WHS
) and the cool -
ing activation point is increased by
121
(see 4-pipe graph, WCS ).
The icon is displayed to indicate that the “non-occupied/holiday” mode is active.
If one of the digital contacts is configured as an “economy or boost” remote contact
015
=4 (DI1) or
017
=4 (DI2) or an analogue
input is configured as an economy/boost contact
019
=11 (AI1) or
021
=11 (AI3) or
023
=11 (AI3), the economy or boost
mode can be activated if the corresponding contact is in the appropriate position (see “36. Digital and analogue input logic”
page 126 ).
In “economy / boost” mode, the choice between economy or boost depends on the signal from the parameter
120
.
2-pipe systems (
014
= 0, 1):
If
120
<0 the boost function is available:
The heating setpoint is increased by
120
(see 2-pipe heating graph, WHS ), the cooling setpoint is reduced by
120
(see
2-pipe cooling graph, WCS )
If
120
>0, the economy mode is taken into account:
The heating setpoint is reduced by
120
(see 2-pipe heating graph WHS ), the cooling setpoint is increased by
120
(see 2-pipe
cooling graph, WCS )
4-pipe systems (
014
=2, 3, 4):
If
120
<0, the boost mode is not available:
The “boost” mode is not available in 4-pipe operation. The parameter is not considered if negative.
If
120
>0, the economy mode is taken into account:
I n “economy” mode, the heating activation point is reduced by
120
(see 4-pipe graph,
WHS
) and the cooling activation point
is increased by
120
(see 4-pipe graph,
WCS
).
The “ ECO ” icon is displayed to signal the “economy or boost” mode.
The “non-occupied/holiday” mode has priority over the economy mode when both modes are activated.
