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.
