INTRODUCTION

- The new DINUY Touch Temperature Controllers are built on a functional evolution of the Laüka Capacitive Switches.

- Two different references are available:

· TM KNT 001: with button for setting the Fan-Coil Speed.

· TM KNT 002: with button for setting the HVAC Special Mode.

- Incorporates a Display which shows the Set-point Temperature or the measured one, as well as the Relative Humidity.

- It has 4 keys with preset functionality:

- Among their keys, there are 2 freely configurable buttons, which can be configured as Switch, Dimmer, Control of Blind /

Shutter, Scenes, etc.

- Incorporate Temperature, Luminosity and Humidity sensors.

- Its main functionality is complemented by 4 Binary / Analog Inputs, which can be connected to a Door / Window Sensor or

a DINUY Temperature Probe.

- Allows enabling and configuring one Heating and / or Cooling Thermostat.

- The 2 free-configuration buttons incorporate 2 configurable RGB LEDs.

- They do not need external supply, only the KNX Bus.

- Device designed for flush mounting into universal switch boxes.

- Programming and commissioning via ETS5 or later version.

this way, it is possible to trigger 2 different actions depending on the length of the action.

- If there is no distinction between Short and Long press:

· Cyclic transmission: Sets the cyclical sending of the object “[PB] Press”.

· No: It will not be updated cyclically, but state transmission can be enabled after recovering bus voltage.

· If OFF state: The object “[PB] Press” will be cyclically sent if its value is “0”.

· If ON state: The object “[PB] Press” will be cyclically sent if its value is “1”.

· Yes: The object “[PB] Press” will be cyclically sent if its value is “0” or “1”.

· Action on Closing the contact: Action to be carried out when the key is pressed.

· Scene Control:

· Show “Disable Button” object: Allows activating/deactivating the key through the object "[PB] Disable

Button". Writing a "0" in this object, the key will be enabled, while if a "1" is written the key will be disabled
and will not send telegrams to the bus.

· Debounce time: Parameter to adjust the bounce suppression time when there is a switch. Prevents

multiple unwanted actions, caused by the rebound when a contact is closed.

· Contact type: Sets if it is a Normally Open or Normally Closed contact.

· Type of Scene Control:
o 8 Bits Scene:

▪ Scene number: assigns a Scene number to the input. It can be an 8-bit scene (1 – 64).
▪ Short Press: allows assigning a specific function to a short pressing: recover a scene or

ignore it.

▪ Save Scene:

▪ No: the Scene cannot be saved through the key.
▪ On Long Press: the Scene is saved after a long press.
▪ With Object value = 1: the scene is saved setting when the object “[PB] Long Press: Save

Scene” is “1”.

▪ On Long Press if Object value = 1: the scene is saved with a long pressing if the object “[PB]

Long Press: Save Scene” is “1”.

Button". Writing a "0" in this object, the key will be enabled, while if a "1" is written the key will be disabled
and will not send telegrams to the bus.

· Debounce time: Parameter to adjust the bounce suppression time when there is a switch. Prevents

multiple unwanted actions, caused by the rebound when a contact is closed.

· Contact type: Sets if it is a Normally Open or Normally Closed contact.

· Distinction between Short and Long Press: allows to distinguish between a short and a long pressing.

This way, if the differentiation is made, two different actions can be carried out depending on the length of
the press. Two different objects will be available.

Configurable Buttons – LED Configuration

· LED control: Allows parameterizing the activation of the button’s LED.

o Via communication object: the object “[PB] LED “Button X” is enabled whereby the LED can be switched on

or off. It will also be possible to set the polarity of the object through the parameter "LED ON when...".

o When the button is pressed: the illumination of the key depends on whether it is physically pressed, or not.

· ON / OFF State: Determines the status of the LED: brightness level, RGB color and behavior, when the key is active or

not (object at 0/1 or the key is pressed / not pressed).

Internal Temperature Sensor

· Enable Temperature Sensor: The built-in temperature sensor can be enabled, or not, depending if it will used as the

temperature source for the Thermostat control.

· Temperature Sensor calibration value: A correction can be added or subtracted (between -5ºC and + 4.9ºC) to the

measurement received from the built-in sensor, in the event that there is a deviation between this value and the real
temperature of the room.

· “Temperature Sensor” enabled after recovering bus voltage: Determines if temperature sensor functionality will be

enabled after recovering bus voltage.

· Base time to send Temperature: How often the temperature value is sent. The time between each transmission results

from the multiplication "Base" x "Factor".

· Temperature variation for sending value: Measured temperature sending when it changes a certain value. If the

difference from the last measurement is higher than the set value, the temperature will be sent before the sending period
elapses.

· Protection Alarms:

· Over-Heating Temperature: When this value is reached the “[Temp] Temperature Sensor Over-Heating”

object is set to “1”.

· Over-Cooling Temperature: When this value is reached the “[Temp] Temperature Sensor Over-Cooling”

object is set to “1”.

· Hysteresis: A value, in tenths of a degree, to prevent successive resending of the object in case the

temperature fluctuates continuously around the threshold.
