Second Stage Menu
- Second Stage differential. Temperature that the system must
surpass to activate the second stage of auxiliary heat. Values: 1 to
5˚C/2 to 10˚F in increments of 0.5˚C/1˚F. By default, 1˚C / 2˚F.
- Second Stage Hysteresis. Defines the hysteresis for the operation
of the second stage. Values: 1 to 5˚C / 2 to 10˚F in increments of 0.5˚C
/ 1˚F. By default, 1˚C / 2˚F.
- Min. Time Exhausted. Minimum time that the first stage must be
active before the second stage of auxiliary heat can be activated.
Possible values are 0, 45, 60 and 120 minutes. By default, 45 minutes.
− Away mode settings. This option configures the following parameters of the
unoccupied user mode and the vacation user mode.
o
Hysteresis. If the set point temperature is surpassed by the differential
defined, the zone will cease demand. Range: 1 to 3.5˚C / 2 to 7˚F in steps
of 0.5˚C / 1˚F. By default, 3˚C / 6˚F.
o
Override Time. Sets time that the zone will resume the selected away
mode when the user touches the controller screen during an away period.
Values: 10 to 120 minutes in steps of 10 minutes. By default, 60 minutes.
− Autochange. This option allows the user to configure the three values that
define the auto-changeover operation that sets the mode of the indoor unit.
o
Setpoint Differential. Defines the minimum differential between heating
and cooling set points. Values: 0 to 3.5˚C / 0 to 7˚F in increments of 0.5˚C /
1˚F, by default 1˚C / 2˚F.
o
Mode Switching Protection (min). Defines the minimum run time before
allowing a mode change. Possible values are 15, 30, 60 and 90 minutes. By
default, 30 minutes.
o
Heat OVR Temp. If a zone has a higher heating demand than this
temperature, the system reverts heating operation even if the cooling
global demand exceeds the global heat demand. Possible values are: Off,
1.5 to 4˚C / 3 to 8˚F in increments of 0.5˚C/1˚F. Default value: Off.
− Anti-freezing. This feature prevents the room temperature from lowering
below 12˚C / 53˚F, although your zone is off. It is deactivated by default.
− Room temperature. This option allows the room temperature and relative
humidity to be shown/hidden. By default, the room temperature is shown.
− Heating stage. This option configures the following parameters of the
Air+Radiant control stage (see parameter Control stages for more information):
o
Temperature gap. Defines the temperature gap after which the
second stage must be activated.
o
First stage. Defines the first stage to operate: Air or Radiant.
