UVR1611

Heating - DL-Bus (Technische Alternative) COLLECTION C

Introduction

The UVR1611 unit is a freely programmable universal control system.

The UVR1611 universal controller can be freely programmed using function modules to match any system configuration for heating room management.

• The DL bus runs at 12 volts.

• The data frame consist of 63 bytes (excluding sync and CRC).

• The data are transmitted @ 488Hz, therefore the transmission of one data set takes about 1.4 seconds.

Wiring

Protocol

Setup

Note

A new device task must be created for each value to be read from the DL bus!

Task settings

• Device: Heating - DL-Bus (Technische Alternative)

• Name: Name of the task (example name ValueN, where N is a number).

• Enable: Should the task be enabled or not

Sensor

• 1st GPIO: DL bus input e.g. GPIO 14 (D5)

• DL-Bus Type: UVR1611

Note

The settings for 1st GPIO and DL-Bus Type must be the same for all used DL bus tasks!

Inputs

Note

The description of the Frame data and the related Frame bytes can be found in the section Protocol!

Data acquisition

• Send to controller 1..3: Check which controller (if any) you want to publish to. All or no controller can be used.

• Interval: How often should the task publish its value (10..60 seconds is normal).

Note

Interval not less than 10 seconds! The reading of the DL bus happens twice per interval.
