This document concerns the oumanSerial module version 0.9e distributed
with taloLogger v1.0c.
This document contains information about the taloLogger applications oumanSerial
data source module, supported controller types and data provided by the module.
Supported Ouman controller types
The supported Ouman controller device types, that can be used as device types
for the oumanSerial module, are:
EH202S
EH202G
EH203G
EH203T
EH201T
EH201L
EH201V
EH201G
If you have suggestions or comments on the models and their datapoints or actual
ground heat pump models using the controllers, please contact
the module author by email (olammi at iki dot fi).
Data points for controller types
Each of the device types describe a configuration profile for the
oumanSerial module. The profile provides information about the
available data points and their types on the controller. The
devices have many common data points, but also device spesific
ones or the same data points (point ID) are available from multiple devices,
but the measured temperature for example might have different meanings.
The tables below show the profiles for each device type. Data point has an ID,
which describes from which data location on the Ouman controller the corresponding
data is retrieved. The type field describes the type of the data. Possible
values are listed in the following table:
temp100 |
A temperature value with two numbers after the decimal point.
(result is calculated inside a module from a signed 16-bit integer retrieved from
the controller, by dividing it by 100). |
uint16 |
An integer value (16 bit unsigned integer) |
Most or all of the device models have the system state variable ("Tilamuuttuja")
listed as a data point. The state variable is an 16 bit unsigned integer. All
of the 16 bits represent an on-off/1-0 state. Known state bitmasks and their meanings
are listed below each devices data point table.
EH202S
Known to exist on Geopro SH ground heat pumps.
