First Stage Menu.
- First Stage Differential. Temperature that the system has to surpass to activate the first 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.

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.
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.
- 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.
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.
· Away mode settings. This option configures the following parameters of the unoccupied user mode and the vacation
user mode:
- 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.
Override Time. Sets time that the zone will resume the selected away mode when the user touches the
-
thermostat screen during an away period. Values: 10 to 120 minutes in steps of 10 minutes. By default, 60 minutes.
· Heating stage. This option configures the following parameters of the Air+Radiant control stage (see parameter
Control stages for more information):
- Temperature gap. Defines the temperature gap after which the second stage must be activated.
- First stage. Defines the first stage to operate: Air or Radiant.
· BACnet. This parameter displays the Device ID, the uplink port, the IP address, the subnet mask and the Gateway IP
and allows you to modify them. Press on the value you want to change, modify it and then press to confirm. The values
by default are:
- Device ID: 1000
- Port: 47808
- IP Address: DHCP
Supply temperature (only available in installations with Airzone VAF 10 KOhm NTC thermistor). This option allows the
·
system demand to be ignored if the supply temperature exceeds a certain limit. The selectable heating cut out
temperatures are 38-46-54-62-70˚C / 100-114-129-143-158˚F. By default, the system will stop heating if the supply
temperature reaches 54˚C / 129˚F.
Note: The system will not generate heat until past 4 minutes (minimum) from the shut of demand.

Fan Delay (s). Defines the delay time (in seconds) to turn off the fan when there is no demand from
§
the Auxiliary Heater. Possible values are 0, 45, 60 and 120 seconds.
