WKRCD4 allows to control / communicate with older heat pumps from Waterkotte that have a control unit called Resümat CD4 with an RS232 serial interface. Newer heat pumps from Waterkotte typically have a modbus interface that can be controlled with module ModbusAttr.
CD4 control units with software version 7000, 8000 or 8011 can be controlled with another version of the WKRCD4 module.
Availability
The module has been checked in to the contrib area.
Prerequisites
This module requires Device::SerialPort or Win32::SerialPort module. Make sure to set "Modem-Klingelzeichen" and "Fremdzugriff" to the lowest possible value.
Define
define <name> WKRCD4 <devicename@speed> <Interval>
The module connects to the heat pump through a serial interface and actively requests data from the heat pump every <Interval> seconds
Example:
define WP WKRCD4 /dev/dualser0@9600 60 attr WP stateFormat Status attr WP event-min-interval .*:3600 attr WP event-on-change-reading .*
Configuration of the module
Apart from the serial interface and the interval there is nothing that needs to be defined.
Get-Commands
There are only two parameters for which an explicit GET has been implemented. Most values are just readings that are automatically requested:
Hzg-TempBasisSoll WW-Temp-Soll
Set-Commands
There is only one parameter that can be changed:
Hzg-TempBasisSoll
Supported readings
The module extracts the following readings from the heat pump:
