12.2 ETS parameters (continued)
base Set Point temperature:
This parameter (interval: 0.1°C) represents the default setpoint
temperature of the system.
Every time the system mode switches between Comfort and ECO this
setpoint will be sent on the bus.
In this way Comfort mode will return to the default setpoint (even if
the customer had previously changed it) and ECO mode will always
have the same setpoint (“Base Setpoint – actuator delta” in the Heating
function or “Base Se actuator delta” in the Cooling function).
Number of tubes:
With this parameter you have to define whether the system is working
with 2 or 4 tubes, the choice must be the same as for the actuator
working with the thermostat.
2 tubes – the icons for the Heating/Cooling functions and Heating ON/
Cooling ON will depend on objects 13 and 14 as explained in the object
section. Objects 15 and 17 will be inactive (there is only one valve).
4 tubes – the icons for the Heating/Cooling functions and objects
13 and 14 will be inactive (there is no need for the Heating/Cooling
functions as the system is able to heat and cool at the same time).
Insensitive zone between heating/cooling:
Only for 4-tube installations (or 2-tube installations with automatic
changeover between Heating and Cooling) you MUST configure this
parameter with the same value as the corresponding parameter on the
actuator. In 2-tube installations without change between heating and
cooling the parameter is zero.
This is useful when the actuator is in cooling mode and sends back a
different setpoint on the bus (setpoint status = se insensitive
zone); in this case the display will show the setpoint sent instead of the
status.
Type of object for valve:
With this parameter you can choose the type of object (1 bit or 1 byte)
to communicate the status of the heating/cooling valve(s).
The choice must be the same as for the actuator.
1 bit – objects 15 – 16 are not active, objects 17-18 are active.
1 byte – objects 17 – 18 are not active, objects 15-16 are active.
add Object ”hvaC mode”:
If yes, object 8 (HVAC mode) is active.
add Object ”hvaC Status”:
If yes, object 7 (HVAC status report bit) is active.
To be used only with actuators using the same object.
add temp. setpoint limit objects:
If yes, objects 5 and 6 (Temperature setpoint limit (high) and (low)) are
active.
If not, the setpoint limits are fixed (7°C and 35°C).
Use Fan functions:
If No, no other parameter, Fan object or Fan icon is available.
If Yes, you can use the Fan functions.

12.2 ETS parameters (continued)
Fan Speed setpoint type:
With this parameter you can choose the type of object (1 bit or 1 byte)
to communicate the speed of the fan.
The choice must be the same as for the actuator.
1 bit – objects 19, 24, 25 and the “setpoint fan speed 1, 2, 3” parameters
are not active, objects 20, 21, 22, 26, 27, 28 are active.
1 byte – objects 20, 21, 22, 26, 27, 28 are not active, objects 19, 24, 25
are active.
Fan Speed setpoint 1:
Only if Fan Speed setpoint type = 1 Byte.
This is the fan speed value (%) sent on the bus (Object 24) by the control
panel when speed 1 is selected via Pushbutton.
It is also the highest limit (if Object 24 <= Fan speed setpoint 1) to
display the Fan speed 1 icon.
Fan Speed setpoint 2:
Only if Fan Speed setpoint type = 1 Byte.
This is the fan speed value (%) sent on the bus (Object 24) by the control
panel when speed 2 is selected via Pushbutton.
It is also the highest limit (if Fan speed setpoint 1 < Object 24 <= Fan
speed setpoint 2) to display the Fan speed 1 and 2 icons and the lowest
limit (if Fan speed setpoint 2 < Object) to display the Fan speed 1, 2 and
3 icons.
Fan Speed setpoint 3:
Only if Fan Speed setpoint type = 1 Byte.
This is the fan speed value (%) sent on the bus (Object 24) by the control
panel when speed 3 is selected via Pushbutton.
