2 Description of the configuration wizard
Configuration with the wizard
Configuration with the wizard takes place in several
steps. These are described below:
1) Add the function blocks required for the installed
heating system components. Choose your settings
and options individually in each function block.
2) When you have added all the necessary function
blocks, set the individual connections between
"producers" and "consumers".
"Producers" are components that provide heat or
fuel. "Consumers" consume this heat or fuel.
3) Next, the terminal assignments of each function
block is displayed on the corresponding circuit
board. In this step, the heating system
components are electrically connected. You may
also adjust the terminal assignments during this
step.
4) Finally, the configuration is installed, and the
software rebooted.
After this, you can make customer-specific
adjustments to the heating system, such as: buffer
charging times, room temperatures for the heating
circuit, hot water temperatures, etc.
When you have completed these customer adap-
tations, save this configuration. It is saved in the
ETAtouch control system. You can additionally save it
on a USB stick.
The description below explains the general way
in which the configuration wizard works. Your
heating system's individual configuration depends on
the installed components, and can vary.

You can restore the heating system configuration at
any time. The configuration is restored either from a
configuration saved in the ETAtouch control system or
via a USB stick. The counter readings are not
overwritten by this.
Control systems in a wall mounted box are
supplied with a USB stick for backing up the con-
figuration. Leave this in the wall mounted box after you
have restored the configuration.
Restoring the configuration
1. In the system settings, increase the authoriza-
tion to [Service], and open the system configura-
tion menu with the [Systems configuration] button.
To restore a configuration, press the [Configuration
restore] button. Another menu appears:

[TWIN] function block Configuration parameter
6 Configuration parameter
6.1 [TWIN] function block
Parameters to be set
Set or check the following parameters.
Detailed descriptions of the parameters are provided
below.
Explanation of [Start lag]
This parameter is used to set the length of the delay in
operation of the pellet burner after the buffer has
demanded heat.
If there is still a demand from the buffer after this
period, then the pellet burner will begin operation.
Explanation of [MixValve runtime]
This parameter sets the running time for the mixing
valve actuator, the time needed to turn it from the
closed to the fully open position.
Set the running time according to the information
on the mixing valve actuator's type plate.
Explanation of [Start idle time]
This parameter is used to select the time after which
the TWIN pellet burner no longer performs de-ashing.
The log boiler's turbulators are also operated during
this de-ashing.
The duration of this idle time is set by the [Duration idle
time] parameters.
The time and duration are best set to match those
of the log boiler.
Explanation of [Duration idle time]
The [Duration idle time] parameter is used to select the
duration of the de-ashing idle time for TWIN pellet
burner.
The start time for the idle time is set with the [Start idle
time] parameter.
The idle time should be kept as short as possible.
If noise is not expected to be a nuisance, you
should reduce the value to 0 hours.
Explanation of [Empty ash box after]
This parameter adjusts the quantity of pellets used,
after which a reminder to empty the ash box is
displayed on the screen.
If the ash box is then only partially full, this quantity can
be increased. If you set the value to zero, the reminder
will no longer appear.
