Foreword



The present document describes the ekinex

®

KNX room temperature controller with LC-display (EK-EP2-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 was developed according to the KNX standard for use in systems of control of homes and buildings.

Through the integrated sensor, the device can measure directly the room temperature value that can be used for control and regulation tasks of heating, cooling and ventilation. Via the bus the device can furthermore receive temperature values from 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.

1.1

Function

The main function of the device is to control the temperature of the air mass of the room by means of the actual temperature (T eff

), measured by the device itself or received by the bus, and of the setpoint temperature (T set

) set by the user; comparing the two values and a series of parameters set before the 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 brightness 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;

• 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;

• temperature displaying (measured, setpoint and outdoor values in °C or °F), alarms and errors (with alphanumeric codification);

• signaling opening windows;

• limitation of the surface temperature for floor heating radiant panels;

• anticondensation protection for floor and ceiling cooling radiant panels;

• antistratification function;

• delayed fan start (“hot-start” function) time-scheduled or depending on the conveying fluid temperature measured at the coil battery.

Sensors



The room temperature controller is equipped with three sensors:

• temperature (1);

• brightness (2).

Positioning of the sensors: temperature (1), relative humidity (2) and brightness (3).

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 ± 2.5 K 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 ekinexpushbuttons).

5.2

Brightness sensor

The integrated brightness sensor allows the measuring of the light intensity of the room. The sensor can be used to automatically adjust the backlight of the LC-display, but its value can also be sent on the bus via the

Object Communication 1 Brightness value.

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 - 2.5 °C ... + 2.5 °C (step: 0.1 K).

About the sensor timeout

The system of internal control of the thermostat monitors cyclically the updating status of the values of the external sensors (from bus) and the inputs when the timeout setting expires. In case no updated value has been received, the regulation function is suspended, an alarm is displayed on the display through the symbol and the corresponding alarm code (see also the list of alarms in the paragraph Diagnostics).

About the weighted temperature

The device allows the acquisition of the room temperature in three ways:

1) from the temperature sensor integrated in the device;

2) from an external temperature sensor connected to a device input configured as analogic (Inputs



Input 1 or 2 = [AI] room temperature sensor);

3) via bus from another KNX device, e.g. from an ekinex pushbutton (External sensors (from bus)



Room temperature = enabled);



Application Manual

Page 28



To optimize or correct the room temperature regulation in special cases (in large rooms, in presence of strong asymmetry of the temperature distribution, when the installation of the device is in a position not suitable, etc.), the device can then use a weighted average between two temperature values. The weights are assigned by the parameter

Relative weight

that assigns a ratio of the two values.

 the information content to be displayed may be reduced da visualizzare può essere ridotto (two options: partial and temperature only).

Backlight

The default backlight of the display can be configured according to the installation location and light conditions of the room. The backlight intensity can be set to a fixed value (in %) or automatically adjusted by means of the brightness sensor integrated in; for this function it is necessary to enable the brightness sensor.

About the heating/cooling terminals

The application functions of the room temperature controller configurable with ETS are particularly suitable for the control through general-purpose or dedicated KNX actuators of the following heating/cooling terminals:

• radiators;

• elettrical heaters;

• fancoils;

• radiant panels;

• dehumidification units;

• radiant panels + radiators (as auxiliary system);

• radiant panels + fancoils (as auxiliary system);

• radiant panels + dehumidification units.

About the heating/cooling switchover

The switchover between the two seasonal modes (heating / cooling) may happens as follows:

1) manually on the device by the end user;

2) automatically by the device;

3) from the KNX bus through a dedicated communication object.

Manual switch-over (mode 1)

The manual switch-over is suitable for bus systems with one or a limited number of room temperature controllers. If the devices have been configured for this purpose, the user does the switch-over manually on the device (that acts as a "master" for the switch-over function); the device sends on the bus the output communication object [DPT 1.100 heat/cool] that switches possibly other room temperature controllers

("slave" devices) connected through a dedicated group address.

Automatic switch-over (mode 2)

The automatic switch-over is suitable for a 4-pipe hydraulic configuration of the heating/cooling installation

(used e.g. for fan-coil units or ceiling radianti panels). Also in this case the information can be sent on the bus with the output communication object [DPT 1.100 heat/cool]; the difference from the first mode is that switching is performed automatically on the basis of a comparison between the values of the actual temperature and the setpoint temperature. In this mode, the manual switching by the user is disabled.

The automatic switch-over is realised with the introduction of a neutral zone according to the scheme in the picture below.

Until the actual (measured) temperature is located below the setpoint value for the heating, the operation is heating; in the same way, if the actual value (measured) is greater than the setpoint value for the cooling, the mode is cooling. If the actual value (measured) temperature is within the dead zone, the previous mode of operation remains active; the switching point of the operation mode for heating / cooling must take place in correspondence with the current setpoint for the active HVAC, in the same way the switching cooling / heating must take place at the setpoint for heating.

Switch-over via KNX bus (mode 3)

The switch-over from the bus requires that the command is received from another KNX device, e.g. another room temperature controller or a Touch&See unit configured to this purpose. The other device works in this way as a “supervisor” device: the switch-over is triggered by the input communication object [DPT 1.100 heat/cool]. In this mode the manual switch-over by an enduser is disabled. Thanks to this mode, the supervising device is able to control the “slave” devices with time-scheduled programs, extending their functionality to that of a chronothermostat (centrally controlled by the supervising device).

About the valve protection function

The function is suitable for heating and cooling systems that use water as thermal conveying fluid and are provided with motorized valves for the interception of a zone or of a single room. Long periods of inactivity of the system can lead to the blockage of valves: to prevent this, the room temperature controller may periodically send a command to open / close the valve in the period of inactivity of the system. This possibility is made available in the application program by means of the parameter "Valve protection function", further defined by the frequency and duration of the valve control.

About the floor temperature limitation function

The floor heating system (warm water version) provides plastic pipes embedded in the concrete layer or placed directly under the final coating of the floor (light or "dry" system) filled by heated water. The water releases heat to the final coating that heats the room by radiation. The standard EN 1264 Floor heating (Part

3: Systems and components - Dimensioning) prescribes a maximum allowed temperature (T

Smax

) for the surface of the floor that is physiologically correct defined as:



T

Smax

≤ 29°C for zones of normal occupancy;



T

Smax

≤ 35°C for peripheral zones of the rooms.

National standards may also limit these temperatures at lower values. Peripheral zones are strips generally located along the external walls with a maximum width of 1 m.

The floor heating system (electrically powered version) involves the laying under the floor coating of an electric cable powered by the mains voltage (230 V) or low voltage (for example 12 or 45 V), possibly already prepared in the form of rolls with constant distance between sections of cable. The powered cable releases heat to the overlying coating that heats the room by radiation. The regulation is based on measurement of the temperature of the air mass, but generally requires the monitoring and limiting of the surface temperature by using a NTC-type sensor which is in contact with the floor surface.

The surface temperature limitation may be realized for several purposes:

 physiological compatibility (correct temperature at the height of the legs);

 when the system is used as auxiliary stage for heating. In this case, the heat losses to the exterior of the building are handled by the main heating stage, while the auxiliary stage only works to keep the floor temperature at a comfortable level (for example in bathrooms of residential buildings, sports centers , spas and thermal baths, etc.);



Application Manual

Page 39



 protection against damages of the final coating due to an accidental overheating. Note that the warm water radiant panels are usually already equipped with a safety thermostat (with intervention on the hydraulic mixing group), while in the case of electrical power this device is not usable and it is common practice to realize a temperature limitation with a surface temperature sensor connected to the device.

About the anticondensation protection function

The objective of this function is to prevent the condensation on the thermal exchange surfaces of the installation or building when cooling is working. This function is mainly used in systems with thermal exchange consisting in surface terminals such as for the floor and ceiling cooling radiant systems. In this case the hydraulic circuits contain refrigerated water; usually the latent loads (due to the increase of air



Application Manual

Page 42



humidity in the room) are handled by air-conditioning units and the temperature and humidity conditions are far from those that could cause condensation. If this is not done in a satisfactory manner, or in case of stop of the air-conditioning units, it is necessary to provide additional safety measures to prevent or restrict the accidental formation of condensation on cold surfaces.

If an anticondensation sensor is used, it is necessary use a device provided with a potential-free signalling contact. The following options are available:

 the connection of the signalling contact to an input of the room temperature controller configured as digital (Inputs



Input 1 or Input 2 = [DI] anticondensation sensor). The signal coming from the sensor is received and processed directly by the room temperature controller (case 1a of the table);

 the connection of the signalling contact to an input channel of another KNX device, e.g. a pushbutton interface or a binary input (External sensors (from bus)



Anticondensation sensor = enabled). In this case the signal of the sensor is transmitted to the room temperature controller through the status of a communication object (case 1b of the table).

About the delayed fan start (“hot-start”)

This function is used in case the fan forces in the room air passing through a heat exchange coil (as in the case of the terminals to the fan-coil). In the heating mode of operation, to avoid possible discomfort caused by the dispatch of cold air in the room, the room temperature controller does not start the fan until the fluid has not reached a sufficiently high temperature. This situation normally occurs at the first start or after long periods of inactivity. The function can be carried out by:

1. a temperature control (through a temperature sensor on the coil exchange battery);

2. a delayed start (function approximated);

In the first case the temperature of the heat conveying fluid is acquired at the exchange battery. The function then has an effective temperature control, but for the execution is necessary that:

 the heat exchange coil is equipped with a sensor of minimum water temperature that acquires the temperature of the heat conveying fluid;

 the sensor is connected to an input of the room temperature controller (configured as analog) or to another KNX device with an analog input .

In the second case just sets a time delay starting from the flow request; there is no temperature control. The effectiveness of the function depends on a field measurement of the time actually required to have sufficiently warm air from the terminal.

About the antistratification function

This function is used in the case of heating systems with thermal exchange of convective type for rooms with height and volume much higher than usual (atriums, fitness facility, commercial buildings, etc.). Because of the natural convection - with warm air rising to the highest altitudes of the room - the phenomenon of air stratification occurs, with energy waste and discomfort for the occupants at the same time. The function opposes to the air stratification, forcing the warm air downwards.

The antistratification function requires:

 rooms of great height;

 availability of ventilation devices able to force the air movement downwards (opposed to the natural convective movement of warm air);

 measuring of the temperature at two heights through the installation of a second temperature sensor at an adequate height in order to measure the actual air stratification (the main room temperature controller is supposed to be installed at 1.5 m).

For rooms with ordinary height (2,70÷3,00 m) the DIN 1946 standard recommends not to exceed 2 K/m in order to have an adequate comfort; this gradient may be bigger in higher rooms.

About the 2-stage configuration with fan-coils as auxiliary stage

The fan-coil units may be used both as a main stage and secondary stage. As main stage they can be combined only to radiators as auxiliary stage. If, however, the main stage is done with (floor or ceiling) radiant panels, the fan-coils can be used as auxiliary stage. In the latter case they work in automatic mode with a configurable offset with respect to the temperature setpoint for the main stage, and then carry out their compensation function while the main stage is brought in temperature with bigger inertia.

The

Ventilation

folder, that is unique, configures a main or a auxiliary stage depending on the settings choosed in the

Heating

and

Cooling

folders. Similarly, the display interface will act on manual / automatic and manual forcing of the only fan-coil.

A particular case occurs when a fan-coil unit works in a season as auxiliary stage and in the other one as main stage. It is for example the case of:

 a radiant panels system that works only for heating and has a fan-coil as auxiliary stage; the same fan-coil works as main stage for cooling;

 a radiator system that has a fan-coil as auxiliary stage for heating; the same fan coil unit functions as main stage for cooling.

In these cases with the configuration adopted, the following steps are necessary:

1.

Important!

If the fan-coil system has a 2-pipe hydraulic configuration, the objects 163 Auxiliary heating output command (1 bit) and 162 Cooling out command (1 byte) have to be set in logical OR in the actuator for controlling the fan-coil which in this case is unique.

An alternative solution that avoids the setting of a logic OR can be realized by configuring a main stage for heating and cooling with radiant panels through separate valves and an auxiliary stage for heating and cooling fan coil through combined valves. The offset of the auxialiary stage for cooling is set to the value 0

(zero); this corresponds to a configuration for main stage. The object 162 Cooling out command (1 byte) is not connected so that the radiant panel system works only for heating.

Scenes



The folder allows the scenes configuration (up to 8), assigning to each one an identification number and the operating mode to be activated when recalled (e.g. with an ekinex pushbutton or another KNX device with this function). If

Learning mode = enabled

, receiving a telegram of scene storage determines the association of the scene to the operating mode currently set on the device.

About the card holder function

The information of card insertion (removal) in (from) a card holder allows you to directly control the temperature by means of the room thermostat, while sending the object value on the bus allows you to control other room functions with KNX (lighting, electrical loads, feedback status for the hotel reception, etc.) depending on the configuration done with ETS. The value of the setpoint temperature and the switching have to be defined with the hotel responsible in accordance with the target of energy saving and level of service to be offered to the guests.



Application Manual

Page 52



Conventional (not KNX) card holder

With a conventional card holder the status (card present or absent) of a signal contact is detected through an input of the device configured as

[DI] card holder contact sensor

. This way you can detect only the insertion and extraction of the card, but it cannot be detected e.g. the access of users with different profiles (guests, service staff, maintenance workforce).

KNX card holder

With a KNX card holder you can differentiate the switching to be carried out; this is not resolved by the parameters of the room temperature controller, but through the definition of scenes that are received by the device. Depending on the available device, advanced functions are possible (e.g. different user profiles).
