- The control algorithms of the temperature control are configurable, either the switching
2-point feedback control, the switching PI control (PWM) or the continuous PI control.
- The command value output 1-bit (switching) or 1-byte (continuous).
- The adjustable control parameters for the PI control are "Proportional range" and "Reset
time", for the 2-point feedback control "Hysteresis".
Setpoint values
- Each operating mode can be assigned its own temperature-setpoints (for heating and/or
cooling).
- The setpoints for the additional level are derived by a configurable level offset from the
values of the basic setpoint.
- The basic setpoint shift is possible by means of communication objects.
Functions
- Switching between "Heating" and "Cooling" can be automatic or object-oriented.
- Deactivating the feedback control possible using separate 1-bit objects.
- The comfort extension is possible by pressing a configurable presence button or presence
detector in the night or frost/heat protection mode.
- The length of the comfort extension can be parameterized.
- The status information is configurable and can be transmitted to the bus via an object
(1-byte / 1-bit).
- Deactivating the feedback control or the additional level is possible using separate 1-bit
objects.
Room temperature measurement
- The room temperature can be measured by means of an internal or external room
temperature sensor. The external temperature sensor must be a KNX temperature sensor
coupled via the bus. Alternatively, both temperature sensors can be combined together.
The determination of the measured value from the internal to external sensor is
configurable.
- The polling time of the external temperature sensor is settable.
- The change interval for the automatic transmission of the actual temperature can be
defined in the ETS. Cyclical transmission of the room temperature is possible, too.
- The room temperature measurement (actual value) can be adjusted separately for the
internal and external sensor using parameters.
- The frost protection mode switch-over is possible by the window status or by the automatic
frost protection.
Actuating variable output
- The separate or shared command value output in heating and cooling mode is possible.
This produces one or two command value objects for each level.
- Normal or inverted command value output is configurable
- Automatic transmission and cycle time for command value output are configurable.
Humidity sensor functionality
Humidity measurement
- The humidity is measured by the integrated measuring element.
- Two limiting values can be assigned to the humidity measured value, and if exceeded or
fallen short of, ventilation controllers can be activated, for example.
Dew point determination
- The dew point temperature is calculated by the device on the basis of the determined room
temperature.
- The determined humidity value of the sensor is adjusted by means of the Magnus formula
which is an approximation formula for calculating the saturated vapour pressure depending
on the temperature. It is very accurate (< 0.22 %) in the range between 0°C and 100°C and
is primarily used in meteorology and building physics for determining the dew point.
