Ekinex EK-ET2-TP, EK-ET2-TP-P - Room Temperature Controller Manual

Description

Room temperature controller with humidity and CO 2 equivalent regulator.

Codes:
EK-ET2-TP (for round and square wall box)
EK-ET2-TP-R (for rectangular wall box)

The ekinex® EK-ET2-TP... room temperature controller is a KNX S-mode device for the independent temperature regulation of a room or a zone in a building. It can be installed in houses and buildings (e.g., offices, hotels, private house, etc.).

The room temperature controller is equipped with 3 sensors: temperature, relative humidity and air quality (as CO₂ equivalent). It can also work as a controller for these 3 parameters, that are available for a single zone to be managed. Up to 8 LEDs can be configured, in order to display the operating thresholds for the CO₂ equivalent, the activation of the humidification/dehumidification functionality and the cooling/heating working modes. The device is equipped with an integrated KNX bus communication module and is designed for wall installation on a flush mounting box. Both the programming button and LED are located in the front of the device below the rocker, as well as the 3 sensors.

The device is powered by the KNX bus line and does not require any auxiliary power supply.

Main functional characteristics

The common features to all versions are documented as follows:

• Temperature, relative humidity and air quality (CO equivalent) measuring through the integrated sensors, with possibility of sending the read valued on the bus;
• Two-point (ON/OFF) or proportional (PWM or continuous) room temperature regulation;
• Seasonal modes: heating and cooling with possibility of either local or via bus seasonal changeover;
• Operating modes: comfort, standby, economy and building protection with different setpoint for heating and cooling functions;
• Automatic switching of the operating modes through presence sensor or window contact;
• Weighted average of two temperature values;
• Dew-point temperature computation;
• Temperature regulation (measured and setpoint, as °C), relative humidity (measured and setpoint in percentage), air quality (as CO₂ equivalent concentration, in ppm), alarms and errors (with alphanumeric coding);

Mounting

The device has degree of protection IP20, and is therefore suitable for use in dry interior rooms. The installation of the device requires the following steps.

Mounting with frame

• snap a square frame (f) of the form or flank series, inserting it from the rear of the preassembled thermostat-adapter (d+e);
• insert the bus terminal, previously connected to the bus cable, in its slot on the rear side (see also: "Connection of the KNX bus line"). At this point it is recommended to carry out the commissioning of the pushbutton (see also "Configuration and commissioning") or at least the physical address download;
• insert thermostat and adapter (d+e), completed with the frame (f), in the metallic support (h). Mounting the pushbutton follow the indication TOP (arrow tip pointing up) on the rear side of the device;
• tighten thermostat, adapter and frame (d+e+f) on the metallic support (h) with the two screws (c);
• snap the plate (a);
• snap the rocker (b) to complete the installation.

Mounting position

For optimum regulation the device has to be preferably installed on an internal wall at the height of 1.5 m and at least 0.3 m far from doors. The device cannot be installed close to heat sources such as radiators or domestic appliances or in positions subject to direct sunlight. If necessary, for the regulation may be used a weighted average between two values selected among the following ones: value measured by the internal sensor, value measured by a temperature sensor connected to a device input, value received via bus by another KNX device (e.g. from ekinex pushbuttons).

Switching, display and measuring elements

The device is equipped with a programming LED, 8 displaying LEDs with lightguides for feedback status and 3 sensors.

Switching elements

• Pushbutton (12) for switching between the normal and programming operating mode.

Display elements

• Red LED (4) for indication of the heating mode functionality ON;
• Blue LED (5) for indication of the cooling mode functionality ON;
• White LED (6) for indication of the dehumidification functionality ON;
• Green LED (7) for indication of the humidification functionality ON;
• Red LED (8) for indication that the measured CO equivalent exceeds threshold 3;
• White LED (9) for indication that the measured CO equivalent lies between threshold 2 and 3;
• Blue LED (10) for indication that the measured CO equivalent lies between threshold 1 and 2;
• Green LED (11) for indication that the measured CO equivalent lies below threshold 1;
• Red LED (12) for indication of the active operating mode (on = programming, off = normal operation).

For measuring purposes the device is provided with:

• a temperature sensor (located behind passage 15);
• a relative humidity sensor (14);
• a CO₂ equivalent air quality sensor (16).

Note. Programming pushbutton and LED are accessible from the front side of the device. The device addressing may be easily carried out after the assembly of the frame, removing the rockers. Once the addressing has been done, the device configuration can be later downloaded without pressing the programming pushbutton.

Connection of the KNX bus line

The connection of the KNX bus line is made with the terminal block (red / black) included in delivery and inserted into the slot of the casing.

Characteristics of the KNX terminal block

• spring clamping of conductors
• 4 seats for conductors for each polarity
• terminal suitable for KNX bus cable with single-wire conductors and diameter between 0.6 and 0.8 mm
• recommended wire stripping approx. 5 mm
• color codification: red = + (positive) bus conductor, black = − (negative) bus conductor

In order to supply the KNX bus lines use only KNX bus power supplies (e.g. ekinex EK-AB1TP or EK-AG1-TP). The use of other power supplies can compromise the communication and damage the devices connected to the bus.

The electrical connection of the device can be carried out only by qualified personnel. The incorrect installation may result in electric shock or fire. Before making the electrical connections, make sure the power supply has been turned off.

Configuration and commissioning

Configuration and commissioning of the device require the use of the ETS^® (Engineering Tool Software) program V4 or later releases. These activities must be carried out according to the design of the building automation system done by a qualified planner.

Note. The configuration and commissioning of KNX devices require specialized skills. To acquire these skills, you should attend the workshops at KNX certified training centers.

Configuration

For the configuration of the device parameters the corresponding application program or the whole ekinex^® product database must be loaded in the ETS program. For detailed information on configuration options, refer to the application manual of the device available on the website www.ekinex.com.

Commissioning

For commissioning the device the following activities are required:

• make the electrical connections as described above;
• turn on the bus power supply;
• switch the device operation to the programming mode by pressing the programming pushbutton located on the front side of the housing. In this mode of operation, the programming LED is turned on;
• download into the device the physical address and the configuration with the ETS ® program.

At the end of the download the operation of the device automatically returns to normal mode; in this mode the programming LED is turned off. Now the bus device is programmed and ready for use.
