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 CO2-concentration 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. 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.
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 (Teff), measured by the device itself or received by the bus, and of the setpoint
temperature (Tset) 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 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;

•temperature displaying (measured, setpoint, perceived and outdoor values in °C or °F), relative
humidity (measured and setpoint values in %) and CO2-concentration (in ‰, received from bus),
alarms and errors (with alphanumeric codification);
•signaling opening windows;
•calculation of psychrometric values (dew-point temperature and perceived temperature) with
possibility of sending the values on the bus;
•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;
•sending on the bus of the condition internal or external from the area of comfort (configurable).

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).
