KNX room temperature controller EK-EQ2-TP

Foreword

The present document describes the ekinex

KNX room temperature controller with LC-display (EK-EQ2-TP

version).

1 General information

The device described in the present document works as an electronic digital temperature controller for a room or a zone (consisting e.g. in a group of rooms or a whole floor) of a building and is part of the secundary regulation for heating and cooling. The room temperature controller has been developed

according to the KNX standard for use in systems of control of homes and buildings.

Through the integrated sensors, the device can measure directly in the room the temperature and relative humidity values that can be used for control and regulation tasks of heating, cooling and ventilation. Via the bus the device can furthermore receive temperature, relative humidity and CO other bus devices. The integrated display visualizes a series of information concerning the room controller function. The device is provided with two rockers that can be used for controlling the thermostat function. The two physical inputs may be configured independently as analogic or digital and allow to extend the basic functions, optimizing comfort, safety and energy savings depending on the user or building needs. The device can furthermore report whether the room or zone is in a thermal comfort field configurable according

to the building use, the activities done and other specific factors.

eff

commissioning, the regulation algorithm of the device calculates the control variable value that is converted

to a telegram and transmitted on the bus toward KNX actuators (such as binary outputs, fan-coli controllers, valve drives, etc.) able to control the operation of heating and cooling terminal units.

1.2 Main funcional features

The main functions carried out by the device are:

• temperature and relative humidity measuring through the integrated sensors with possibility of sending the values on the bus;

• 2-points (on/off) or proportional (PWM or continuous) room temperature regulation;

• ventilation control with continuous or 3-speed regulation;

• relative humidity control both in humidification and dehumidification;

• seasonal modes: heating and cooling with local or via bus switch-over;

• operating modes: comfort, standby, economy and building protection with separate setpoint values for heating and cooling;

• manual or automatic control of a fan-coil unit with 2-pipes or 4-pipes connection

• automatic switching of the operating mode when presence/absence of people or window opening is detected;

• weighted average of two temperature values;

5 Sensors

The room temperature controller is equipped with three sensors:

• temperature (1);

• relative humidity (2).

Position of the sensors: temperature (1), relative humidity (2).

The temperature sensor (not to be seen in the drawing) is located under the plastic half-shell for the rockers’ mounting.

5.1 Temperature sensor

The integrated temperature sensor allows the measureming of the room temperature in the range from 0 °C to +40 °C with a resolution of 0.1 °C. To keep into account significant environmental interferences such as the proximity to heatsources, the installation on an outer wall, the chimney effect due to rising warm air

through the corrugated tube connected to the wall-mounting box, the measured value can be corrected by

means of a offset of ± 5 °C or, preferably, can be used a weighted average between two values of temperature chosen from the following ones: value measured by the integrated sensor, value measured by a temperature sensor connected to one of the inputs of the device, value received via bus from another KNX

device (such as ekinex pushbuttons).

5.2 Relative humidity sensor

The integrated relative humidity sensor allows the measuring of the relative humidity value in the room. The measured value allows you to make an advanced room thermoregulation and enlarge the opportunities for a safe operation of certain types of terminal equipments used for cooling. The measured value can also be sent on the bus via the 114 (1 byte) and the 115 (2 bytes) Communication Objects.By means of a calculation performed by the thermostat, on the bus can also be sent psychrometric values obtained from the combined

measurement of temperature and humidity, such as the dew-point temperature, as well as the index of perceived temperature (only in summer mode).

KNX room temperature controller EK-EQ2-TP

6 Input variables

The data that the device usesin its control algorithms and /or to be displayed may come from:

• the internal sensors;

• sensors or digital signals connected to the two physical inputs of the device;

• the KNX bus through standard Communication Objects.

The processed data can also be transmitted on the KNX bus as Communication Objects.The classification of

the input variables is shown in the following table.

The device does not have outputs for direct switching or control of heating/cooling terminals or for status or values signalling. The output variables include exclusively communication objects that are sent on the bus,

received and processed by KNX actuators (general-purpose or dedicated to HVAC applications).

Input variables from internal sensors, physical inputs and standard communication objects.

button of ETS) is the following:

Other folders may appear depending on the choices done for the parameters of the folders represented in

the main tree structure.

7.1 About EK-EQ2-TP

The folder About EK-EQ2-TP is for information purposes only and does not contain parameters to be set.

The information given is:

Device operation as

stand-alone

stand-alone/chrono

slave

If configured as stand-alone/chrono the operating mode can be selected manually on the device; in that way, the commands received via bus are ignored. If changing the operating mode the watch symbol is selected, the commands received via bus are accepted again. If configured as slave, the room temperature controller receives from a KNX device (acting as supervisor) HVAC modes, setpont values, etc.

Temperature displayed unit

Celsius

Fahrenheit

Default displayed information

actual temperature

temperature setpoint

The actual temperature is the value by which the device performs the temperature regulation. It may be the value measured from a single sensor (internal, from the bus or from an input) or the weighted average of the temperatures measured by a main sensor and an additional sensor. The displayed setpoint temperature is that of the operating mode currently set on the room temperature controller (deduced from the symbol on).

Time to return to default display information

5 s

[other values in the range 10

s … 1 min]

Time interval after which the display automatically switches between the manually recalled information to the default information.

Button function level

end user

system integrator

This parameter allows you to partially inhibit the functions that can be recalled using the rockers.

Time to exit change without saving

8 s

[other values in the range 2

s … 12 s]

Time interval without further pressing of the rockers at the end of which the device exits the procedure without saving the current changes.

Values

Delay after bus voltage recovery

00:00:04.000 hh:mm:ss:fff

[range 00:00:04.000 …

00:10:55.350]

Time interval after which the transmission of the telegrams on the bus starts after the power supply is restored. The delay affects both the event-driven transmission and the cyclic transmission of a telegram. Regarding the latter, the counting of the pause interval for retransmission starts at the end of the time of initial delay. The field has format hh:mm:ss:fff (hours : minutes : seconds .milliseconds): the default value 00:00:04.000 corresponds to 4 seconds.

KNX room temperature controller EK-EQ2-TP

Information displayed as default

One information between the actual temperature and the temperature setpoint is displayed preferably by the digits of the display. The device allows you to retrieve and display a series of other information pressing the

●●●● symbol on the upper rocker; after the time set in the parameter "Time to return to default information"

without further pressure of ●●●●, the display automatically returns to the default information.

Functional level of the rockers

The use of the rockers for controlling the room temperature controller can be partially inhibited in the configuration phase through a filter for the access to the several functions. When using the rockers a

distinction is made between:

 first level functions (= short or long pressing of the rockers) for the end user;  second level functions (= combination of rockers); to the first level are added a few functions for a

system integrator or an installer.

The enabled functional level is set through a special parameter.

The temperature sensor is enabled as default. When the sensor is disabled, the corresponding folder disappears from the

main tree structure of the application program; in this case to have available again the functions for Temperature control you have to enable Room temperature in the External sensors (from bus) folder or set Input X = [AI] temperature sensor (X = 1, 2) in the Inputs folder.

Relative humidity sensor

disabled

enabled

The relative humidity sensor is disabled as default. When the sensor is disabled, the functions that require the value of relative humidity are available only if you enable Relative humidity in the External sensors (from bus) folder. When the sensor is enabled, the corresponding folder appears in the main tree structure of the application program.

Acquisition filter

The acquisition filter calculates an average with a series of measured values before sending on the bus. The

parameter can have the following values:

 low = average value every 4 measurements;  medium = average value every 16 measurements;  high = average value every 64 measurements.

Correction of the measured temperature

The sampling of the temperature value occurs every 10 seconds, while the display is updated every minute. During the configuration with ETS the opportunity is given to correct the measured temperature value within

the offset range of - 5 °C ... + 5 °C (step: 0.1 °C).

7.3 Inputs

The folder Inputs allows you to configurate one or two variables (either digital or analogic) depending on the digital signals or the temperature sensors connected to the terminal blocks of the inputs. The physical values or the detected states can be used locally by the device for temperature control functions and/or transmitted on the bus for other purposes. The folder includes the parameters for configuring independently the inputs 1 and 2. The two inputs are identical; for simplicity in the following only parameters and communication objects

of a single input are described.

7.3.1 Input X

The folder Input X (X = 1, 2) includes the following parameters:

 Input X  Contact type  Filter type  Temperature offset  Cyclic sending interval  Minimum change of value to send (K)  Threshold 1  Value [°C]  Threshold 2  Value [°C]  Hysteresis  Cyclic sending interval
