The Fan Coil Display Operate Control/1.2 application program for the Fan
Coil ambient temperature controller with display controls the device for
heating, cooling or heating and cooling. The ETS shows different parameters
and communication objects depending in the functions selected in the
"Control Function in Use" parameter.
A "2-point control", a "PWM control", a "Continuous control" or a "Fan Coil
Actuation" can be implemented for heating and/or cooling in all controller
functions. A supplementary stage for heating and also for cooling can also
be actuated.
A temperature value can also be received by an additional temperature
sensor via the KNX for improved temperature control in larger rooms.
The measured value is then applied to the ambient temperature control
with a defined weighting.
The ambient temperature controller can be operated with dependent or
individual setpoints. Dependent setpoints mean that the setpoints in standby
and night mode are always based on the basic setpoint, and with individual
setpoints a separate setpoint can be set for every operating mode.
(See also page 93 in Section 4.4 Setpoints at Planning and Application.)
The ambient temperature controller with display has summer compensation
to save energy and to maintain a reasonable temperature difference when
entering an air-conditioned building. A winter compensation function can
also be activated to maintain a pleasant temperature in rooms with large
areas of window during cold weather. (See also page 98 in Section
4.6 Compensation at Planning and Application.)
