FAQ
1. Speed V1 - Fan Inputs, Speed V2 - Fan Inputs, Speed
V3 - Fan Inputs, Automatic - Fan Inputs (objects from
40 to 43 and from 87 to 90): useful for sending speed
force controls to the thermostat or for forcing automat-
ic control.
2. Off - Fan Outputs, Speed V1 - Fan Outputs, Speed V2
- Fan Outputs, Speed V3 - Fan Outputs (objects from
45 to 48 and from 92 to 95): useful for displaying the
current speed of the fan coil.
3. Speed V1 - Disable Fan, Speed V2 - Disable Fan,
Speed V3 - Disable Fan (objects 49, 50, 51 and
96,97,98): useful for sending speed disable controls.
i. Window Sensor (objects 52, 99 and 110): viewing the
status of the window combined with the thermostat on
the supervision software (for example on the computer of
a hotel reception desk) requires you to:
1. Set the input contact as "General use" and use it as an
open window sensor;
2. Assign the desired group address to the "Window
sensor" object (objects 52 and 99) and to an input of a
KNX device (if the thermostat input is used, assign to
this group object no. 110);
3. Assign to this address the "Contact" Address/Object
type inside the Well-Contact Suite software.
l. Temperature: Automatic/Manual (objects nos. 54 and
101): useful for displaying whether the setpoint has been
set from software or manually using the thermostat but-
tons.
m. Fan coil: Automatic/Manual (nos. 55 and 102): useful for
displaying whether the current fan coil speed is managed
automatically by the thermostat or has been forced.
n. Temperature: Disable Local Operation (objects nos. 56
and 103): useful for displaying and sending controls from
software regarding whether or not it is possible to set the
current setpoint on the thermostat manually.
o. Fan coil: Disable Local Operation (objects nos. 57 and
104): useful for displaying and sending controls from
software regarding whether or not it is possible to set the
speed manually from the thermostat.
16. To perform supervision of thermostats using Vimar Well-
contact Suite software, what communication objects
need to be set?
YOU have to set to "Read" the relevant flags of objects from
25 to 32 and from 72 to 79 for each 02952 thermostat.
17. What is the parameter "Time in Manual Fan Mode" used
for?
It is a time indicated in the parameters for which the ther-
mostat remains in "Manual forcing" if the guest has manually
forced the temperatures or speed of the fan coil: when this
time has elapsed the thermostat returns to automatic.
If the parameter is set to "0" it is interpreted as "Time =
infinite" and the manual forcing stays on.
18. An object is needed that goes to "1" if one of the 3
speeds is activated and returns to "0" if V 1/2/3 are
deactivated.
Use the object "Cooling/Heating valve" 34 and 81.
19. Is it possible to take an object to "0" when a speed V-0
is set from the thermostat?
No, it is not possible to set the speed V-0 manually.
20. Is the object "Thermostat Mode - Mode" (object 16 and
63) usable only by Well-Contact Suite or also by other
supervision software?
The object "Thermostat Mode - Mode" is a KNX standard
object, with coding defined by the standard (HVAC Operating
Mode 20.102), therefore it can also be used by other super-
vision software; there is also the related object for reading the
mode (objects 17 and 64).
0 = Automatic
1 = Comfort
2 = StandBy
3 = Economy
4 = Protection
5-255 = Reserved values
21. Is it possible to manage a general valve if there is more
than one thermostat?
This function is possible only with a logic module. It is also
possible to use a Well-contact Suite functional logic, which
will operate only if the supervision software is active and
communicating with the bus.
22. Is it possible to control a proportional-type fan coil with
one or two supply values?
The thermostat normally controls supply at three levels of
intensity: 33%, 67%, 100%. As can be seen in the following
image, setting the maximum speed to 1 or 2 results in one or
two thresholds (respectively 33% or 33-67%). Other supply
level settings are not possible.
For the touch thermostat 02952 you can still control the pro-
portional fan coil with minimum speed settable from 10% to
50% and with maximum speed up to 100%.
