Multi-function application with RTR and FanCoil 1816/1.0

Function overview

This application provides you with the following func-

tions:

• Temperature control with various display options

• Scene function

• Disable function for push-buttons

• Time control

• Valve control

• Push-button functions

All buttons can be assigned different functions inde-

pendently. You can do the following:

• Switch and toggle

• Dim

• Control blinds

• Save and retrieve scenes

• Select a linear regulator function

• Save edge functions

• Adjust setpoints

• Access operation modes and toggle between them

The status LEDs can also be utilised independently of

one another and in a wide variety of ways.

Group addresses

Group addresses are managed dynamically. Maximum

number of group addresses and assignments: 254 ad-

dresses, 255 connections

Notes on this documentation

This application enables you to implement a multitude

of functions with the push-button. However, which func-

tions are possible in each individual case depends on

the KNX devices being controlled (e.g. dimming actua-

tors, switch actuators etc.). The functions described

here therefore show only the settings for this push-but-

ton.

|Many parameters and their settings are depend-

ent on the settings you have already made for oth-

er parameters. This means that some parameters

will appear or disappear and the values available

for selection will change according to settings you

have already made. These dependencies have

not been shown in the table for reasons of clarity.

All settings are always shown.

|Configurable times (staircase timer, ON delay,

OFF delay, cyclic intervals etc.) are set via the

base and factor parameters. The actual time is giv-

en by the multiplication of the two values. Exam-

ple: Base = 1 second * factor = 3 gives 3 seconds.

|The bold values in a table are the values set dur-

ing factory configuration.

Before you begin, make a few basic settings in the

"General" tab. You can specify the following:

• Whether the operational LED switches off or displays

that the device is operating.

• How the date and time are received.

• Whether and how the time is sent cyclically to the bus.

• How large the start-up delay for the device should be

after bus voltage recovery.

General settings for date and time

Here you set whether the date and time are received by

two communication objects (3 byte each) or by only one

communication object. In the latter case, there is an 8

byte object available.

If you send the time cyclically to the bus, you either have

an output object with 3 byte or one with 8 byte, depend-

ing on which format you selected.

You can find more details on time control, synchronisa-

tion and master-slave functions in the "Time control"

chapter.

Start-up delay

The start-up delay is the time delay between the bus

voltage recovery and the device's functional start. Set a

time after which the current values can be read by other

KNX devices.

Communication objects

You can select the following communication objects:

Here, you set the display options and display functions:

• You can disable the control menu so that the menu

buttons cannot be used to make further changes to

the settings.

• You use the display mode to specify which values you

want to display on the basic display (actual tempera-

ture, setpoint temperature, time, date, external tem-

perature and fan speed). You can display these

values either individually or in alternation. You can

also set the display rhythm for alternating displays.

The display mode can also be set using the control

menu on the push-button.

• For the weekday display, you can set day "1". This

means that the first weekday can be defined as: Fri-

day, Saturday, Sunday or Monday. Each weekday is

then shown in the display with a different number ac-

cordingly.

• Time format and unit of temperature display (Celsius/

Fahrenheit).

• The background lighting on the display can either be

switched off or on at all times, or can be switched on

during operation. You can also set the persistence pe-

riod and the brightness of the background lighting.

|The parameters for the background illumination

and display mode can be changed using the menu

buttons on the push-button (see operating instruc-

tions).

If you use room temperature control ("Control general"

tab), additional possible settings appear:

• You can specify whether or not the operation mode

can be changed when the frost or heat protection op-

eration mode is activated.

• "Access menu setpoint temperature/operation mode

directly" Here, you specify which operation mode you

want to select with a short push of a button on the

menu buttons. You can choose between the control

menu "Set setpoint temperature" or "Set operation

mode".

• On the display, a symbol can show either the current

controller status or whether heating or cooling is acti-

vated.
