Domotic touch screen-thermostat for controlling ON/OFF, PWM and PID temperature (heating and cooling), 2- and 4-pipe system management,
3-speed and proportional fan-coil control, 1 input for flush-mounting or wired NTC temperature sensor, RGB LED backlighting, to be completed
with Eikon Evo Eikon, Arké or Plana cover plates, grey - 2 modules
The thermostat integrates with the By-me home automation system for temperature control in
2 or 4 pipe systems (heating/cooling) and neutral zone (only in 4-pipe systems), with "boost"
function to activate a second source which enables reaching the desired level of thermal comfort
faster. The thermostat is equipped with an RGB backlit display and 5 capacitive buttons for
controlling the temperature set-point, the speed of the fan coil and the configuration of the ther-
mostat operating modes; the display colour is adjusted via the control unit (21509) or EasyTool
Professional software. The thermostat is a universal device with 2 modules for the Eikon, Arkè
and Plana series.

CHARACTERISTICS
• Rated supply voltage: BUS 29 V
• Typical current draw: 5 mA
• Terminals: 2 TP bus, 2 for external temperature sensor
• Hysteresis: adjustable between 0.1°C and 1°C; the adjustment is made by the control unit.
• Temperature measurement accuracy
- integrated sensor: ±0.5°C between 15°C and 30°C, ±0.8°C at the ends
- auxiliary external sensor: as integrated sensor. Over the device's operating temperature the
error of the auxiliary external sensor increases (max 2.5°C @ 80°C)
• Maximum length of cable connecting the external sensor: 60 m. Use a twisted cable with a
minimum cross-section of 0.5 mm (art. 01840)
2
• 2 and 4 pipe system management
• Heating, cooling, neutral zone (only with 4 pipes)
• Control via specific On/Off hot/cold valve By-me actuator with actuator 01851.2 and propor-
tional type (0-10 V, 4-20 mA) with actuator 01466
• Fan coil management (3 speed/proportional, on/off valves)
• Selectable PID or ON/OFF adjustment algorithm:
- the ON/OFF algorithm is the control in which, on exceeding the set temperature increased
by a threshold value (vice versa for air-conditioning), the heating is turned off and then back
on again when the room temperature falls below the set temperature.
- the PID is an advanced algorithm capable of keeping the room temperature more stable. It acts
by turning the system on and off appropriately so as to be like a gradual increase or decrease
in the heating (or cooling) power of the system. Ideal for use in floor heating systems, the
algorithm needs to be properly calibrated according to the type of room and system
• Boost function: control of an auxiliary actuator to speed up the heating or air-conditioning of
the room
• Input for external sensor (art. 02965-20432-19432-14432) whose functions are as follows:
- Substitution of the internal sensor
- Average with the internal one
- Screed temperature limitation
- Viewing only via touchscreen or web server
• Open window management function
• Device can be managed remotely (touchscreen, web server)
• Device can be interfaced with third-party systems
• Interface with capacitive buttons
• Backlit RGB display can be set as fixed colour or Ecometer
• Operating temperature: 0°C - +40°C
This device can be configured only on By-me control panels art. 21509.
CONFIGURATION.
FOR THE OPERATIONS OF INSTALLATION AND CONFIGURATION, SEE THE
INSTRUCTIONS MANUAL FOR THE By-me SYSTEM CONTROL UNIT art. 21509.
The thermostat must be configured with the control unit in a group containing the actuator
dedicated to HVAC control (solenoid valves, circulation pumps, burners, proportional valves).
• Selecting the functional unit (configuration): during group creation, when the control unit
requires pressing the configuration button, simultaneously press the two areas of the display
shown below.
USING THE THERMOSTAT.
• Automatic
The thermostat performs the function of a timer-thermostat, making the climate profile pro-
grammed via the control unit, touchscreens, etc.
• Timed manual
Available only if automatic mode is active, it enables modifying the temperature setpoint to a
settable value and for a settable time. When the set time elapses the system goes back into
automatic mode with the setpoint value for the day and the current time.
To activate this mode, when the thermostat is on Automatic, tap the
• Manual
The temperature is adjusted according to the set setpoint (

The temperature is adjusted according to the set Away setpoint (
• Protection Mode
The temperature is adjusted according to the "antifreeze" setpoint
(if on cooling). This mode, associated with the system protection, prevents damage to the
system or structure.
•
In this mode, the thermostat does not perform any type of temperature control and all the actuators
are shut down.
DISPLAY ICONS AND BUTTONS.
The thermostat display is very sensitive and, to ensure proper operation, you need to make
sure that the power supply of the BUS line has an earthing terminal
to the earth of the electrical system.
INSTALLATION RULES.
• The appliance must be installed in flush- or wall-mounting boxes with the relevant mounting
frames and cover plates, at a height of 1.5 m off the floor, in a suitable position for correctly
detecting the ambient temperature. It must not be installed in niches, behind doors and curtains
or in areas affected by sources of heat or atmospheric factors. In particular, it must not be installed
on outer walls or in association with appliances that generate heat (e.g. regulators or lamps).
• Installation should be carried out in compliance with the current regulations regarding the installa-
tion of electrical systems in the country where the products are installed.
