GENERAL CHARACTERISTICS AND FUNCTIONS
Thermostat
Touch screen electronic thermostat for room temperature
control (heating and air conditioning) of 2 independent
zones, KNX standard home automation system, 1 NO relay
output 4 A 24 V~, 1 input for electronic temperature sensor
or wired temperature sensor, 1 programmable digital input,
RGB LED backlighting, to be completed with Eikon Evo,
Eikon, Arké or Plana cover plates, grey - 2 modules.
General characteristics
The thermostat is suitable for controlling room temperature
(heating/air-conditioning) in 2 or 4 pipe systems (heating/air-
conditioning) and neutral zone (only in 4-pipe systems), with
the "boost" function to activate a second source that makes
it possible to reach the desired thermal comfort faster; it can
interact with other thermostats and with a monitoring unit (PC
with Well-contact Suite software). It can manage 2 climate
zones completely independently (equivalent to two thermostats
A and B). For each zone the heating/air-conditioning modes are
managed according to the related reference temperature. It is
equipped with a relay programmable as NC or NO that can be
used for general use (e.g. lighting, zone solenoid valve closing,
activating electric towel warmer, etc.) or to control speed 1 of
the fan coil, which is managed by thermostat A or thermostat
B. It also has a digital input programmable as NC or NO,
which can be used for other applications such as detecting an
open window. The thermostat features an RGB display with 5
capacitive buttons for controlling the temperature setpoint and
the speed of the fan coil, the configuration of the operating
modes and the selection of thermostat A or B to view/control; it
has an RGB backlit display whose colours can be adjusted via
parameters with ETS.
Display icons Note. In 4- pipe systems, the display may show errors (E1, E2,
E3, E4) as illustrated on the next page.
Behaviour after bus power on/off
Bus power off: -.
Bus power on: the status will be set based on the setting of the
parameters and the corresponding telegrams sent over the Bus.
Behaviour after reset
As for Bus power-on.
N.B. The thermostat saves the comfort and standby setpoints
set manually by the user; if you wish to reset them, set the ETS
parameter "Reset Setpoint Shift in Economy Mode=YES".
When switched to "Economy" mode, the thermostat will reset
the STBY and CNF values.

General characteristics and functions
Thermostat
Neutral zone
The "Neutral Zone" is an operating mode of the thermostat (only
for 4-pipe systems) in which the device keeps the temperature
within a temperature range preset by the Winter Setpoint
and Summer Setpoint (basically, there is no longer the usual
Summer/Winter mode).
If the measured temperature is below the Winter Setpoint, the
thermostat switches on the heating valve and heats the room until
the temperature exceeds the set value (e.g. 20°C for Comfort
mode or 18°C for Standby mode). If the measured temperature
exceeds the Summer Setpoint then the thermostat switches
on the cooling valve and keeps it on until the temperature falls
below the set Summer Setpoint value.
Within the Neutral Zone the thermostat does not switch on any
valves and the temperature can vary freely; this zone is therefore
nothing more than the difference between the Summer and
Winter Setpoints when the room temperature is between the
winter setpoint and the summer one.
To avoid excessive temperature fluctuations, set a limited range
(≤ 2°C) as shown in the figure below.
Setpoint displayed in Neutral Zone operation
When the thermostat is working in the neutral zone, the setpoint
used for the adjustment is always the Current Setpoint, namely
the one relating to the last heating/cooling mode that came into
operation; the value displayed is instead a new setpoint named
"Neutral Zone Setpoint”, which is the average value between
the current summer and winter setpoints.
Changing the temperature of the "Neutral Zone Setpoint” (with
the "+” and "-” buttons on the thermostat) will also cause a
change to the value of the "Shift Setpoint” resulting in a shift
of the two current summer/winter setpoint values; the room
temperature will therefore not become the one set by the guest
but that of the summer/winter setpoint which at that moment
is closest to the value of the current temperature in the room.
Between the two summer/winter setpoints, there is the neutral
zone in which the system is not activated.
Configuration
The KNX 02952 thermostat is configured in Neutral Zone mode
if the following object is NOT connected: "Enable A: Summer -
Winter – control" or "Enable B: Summer - Winter – control".
The KNX 02952 thermostat can operate in Neutral Zone IF:
• The system has 4 pipes
• Winter Comfort Setpoint < Summer Comfort Setpoint
• Winter Standby Setpoint < Summer Standby Setpoint
• Winter Economy Setpoint < Summer Economy Setpoint
• Antifreeze < Too Hot
If these conditions are not satisfied, you can still commission
the thermostat; if there is an error while starting up, the device
will remain in "Protected” mode and an error message will be
displayed.
For example, the following picture shows error 2 which is
equivalent to Winter Comfort Setpoint ≥ Summer Comfort
Setpoint.
Types of errors at the time of configuration
Error No. Description
E1 Selected 2-pipe system instead of 4-pipe
system
E2 Winter Comfort Setpoint ≥ Summer Comfort
Setpoint
E3 Winter Standby Setpoint ≥ Summer Standby
Setpoint
E4 Winter Economy Setpoint ≥ Summer Economy
Setpoint
E5 Antifreeze ≥ Too Hot
N.B. Errors E2, E3, E4 and E5 may also be displayed if the
thermostat is programmed in "4-pipe system" mode without
the neutral zone according to the type of Setpoint shown in the
table.

Communication objects and ETS parameters
Important: The "Time between Heating and Cooling” param-
eter is the wait time it takes for the thermostat to switch from
summer-winter and vice versa. This parameter is especially
useful in some underfloor radiant systems where you set a high
time value to prevent the formation of condensation; this applies
especially when the thermostats work with a neutral zone and
so there could be multiple seasonal changes in a single day.
If instead, depending on the type of system, you want a faster
response of the thermostat, it is necessary to reduce the value
of this parameter.

Setpoint range
Note: In the case of a 4-pipe system, the winter setpoint cannot
take a higher value than the summer setpoint.
CAUTION: When the thermostat is in Neutral Zone mode,
the breadth of this must be progressively increasing for
the different operating modes of Comfort (minimum neutral
zone breadth), Standby, Energy Saving and Protected. This
setting made with ETS ensures that, when the thermostat
changes operating mode, the active setpoint is always at
a suitable value and the thermostat does not start cooling
if it was heating before or vice versa, causing considerable
energy consumption.
