UVR61-3

Heating - DL-Bus (Technische Alternative) TESTING

Introduction

The UVR61-3 unit is a three-circuit universal control system.

The UVR61-3 unit is designed for an energy-saving and cost-effective drying of cellars and other parts of buildings by means of fan control.

The UVR61-3 three-circuit controllers has various thermostat, differential temperature and speed control functions for use in solar and heating systems, too.

  • The DL bus runs at 12 volts.

  • The data frame consist of 34 bytes (excluding sync and CRC).

  • The data are transmitted @ 488Hz, therefore the transmission of one data set takes about 0.8 seconds.

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: UVR61-3 v8.2

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 intervall.
