instead, in addition to the operating mode, the possibility of
viewing Thermostat B is excluded.

39. How do you know the firmware version of a thermostat?
The firmware version of the thermostat can be identified via
the tracking label both on the VIMAR packing box and on the
body of the thermostat. The tracking label is similar to the
one in the following example:

40. In a hotel, the thermostats set to OFF/Economy mode
suddenly all go into STBY mode; why is that?
The mode change has been generated by the Well-contact
Suite software reopening which on starting up queries all the
room pockets to update its supervision on the presence or
absence of guests in the rooms; the pockets respond with
a bit=0 on the presence, but this is the same group that is
also linked to the 1 bit object of the CMF/STBY control of
the thermostats and bit=0 on that group entails an inter-
pretation of the thermostat of the type "guest not in room,
go onto STBY ". The problem can be solved by disabling
the Update flag "U" on the 1 bit object of "comfort/stby" of
the thermostat that is active by default; in this way, when
the Well-contact Suite software queries the pockets, they
respond with a bit=0 on the group but since that flag is OFF,
the thermostat will keep its mode without going onto STBY.

41. If the thermostat is operating in Neutral Zone mode and
the guest changes the current setpoint by adjusting the
thermostat, what happens? Are the setpoints previously
set by ETS or by Well-contact Suite also changed?
No, nothing in particular happens. Acting on the thermostat
changes only the Current Setpoint and not the single mode/
season setpoints, the thermostat functions according to the
set setpoint and the room temperature so it will activate the
heating, cooling or remain in the neutral zone depending
on the heating and air-conditioning setpoints of the current
mode.
42. You cannot change the thermostat mode from the Well-
Contact Suite software (neither from supervision nor
from the Master-thermostat); What can be done?
To send mode messages to the thermostats, the Well-
contact Suite software uses the communication objects No.
16 for thermostat-A and No. 59 for thermostat-B.
43. Is it possible to control a fan coil via a relay belonging to
different devices and not to a 4-output module?
Yes, it is possible. The thermostat automatically performs
an interlocking function between the relays of the various
speeds so it deactivates the relay in use before activating
that of the new speed to switch on; to prevent the guest
from accidentally activating the 2 relays at the same time
causing failure of the Fan coil, in the ETS project it is nec-
essary not to pair the speed forcing objects (objects nos.
38, 39, 40 for thermostat-A and nos. 81, 82, 83 for thermo-
stat-B) to avoid the guest forcing one speed when another
one is already in use (it is not possible to interlock relays of
different devices).
44. Can the various Setpoint communication objects be
added to the same ETS group?
No, each thermostat communication object must be added
to its own dedicated group.
45. Is it possible not to show the icon for swapping between
Thermostat A and Thermostat B on the display?
Yes. So as not to display the icon on the bottom left you
need to Disable the "Enable User Interface" item of the
"Thermostat B" parameter.
46. Using the Setpoint Shift object and resetting this setting
when you switch the thermostat to ECONOMY or OFF/
PROTECTED mode.
If with a supervisor device (touch screen, web server, etc.)
you change the current setpoint of a thermostat, in which
the Reset Setpoint Shift in Economy Mode parameter is set
= yes, via the SETPOINT SHIFT object and, at a later time,
you bring it into ECONOMY mode, when the thermostat is
put back in STBY or CMF mode the value previously set
by the supervisor will not be maintained (conversely, if you
write the value directly on the SUMM/WINT COMFORT
SETPOINT object or on SUMM/WINT STBY SETPOINT
there will not be a reset when the mode changes).
