Scope of delivery
General
Systems with unmixed heating circuit are controlled via the heating circuit
controller. Required heating circuit temperature is determined in the flow,
depending on outside temperature.
The burner control adjusts the heat generator temperature via a switching contact
at the boiler immersion sensor.
The DHW control is accessing a DHW charging pump and controls the DHW
requirement in a DHW tank at the tank immersion sensor.
Intended use
The unit is manufactured in accordance with state of the art technology and
approved safety regulations. Nevertheless, using the unit can cause danger to the
user or third persons, or damage to the unit and other assets. The unit must be
used exclusively as heating circuit controller with burner control and DHW
charging control.
Safety
All electrical connections, safety measures and protections have to be carried out
by an authorised professional electrician according to the valid standards and VDE-
guidelines, as well as the local regulations. The electrical connection must be a
fixed connection according to VDE 0100.

4. Functions with direct access
Manual operation
— Activate by pressing and holding button
— Change heat generator setpoint via buttons
and
— end function by pressing button
Adjustment room setpoint
Press buttons and in the basic display to directly set room day
temperature. Such a variation changes the parameter 06:02 (see parameter
description).
Controller is in manual mode
Function: Manual operation allows manual start-up of the system, e.g. to
perform emission measurement.
The heat generator adjusts the temperature to the set value
— The heating circuit pump runs continuously
— The DHW charging pump runs continuously
Caution!
This function shall only be used by an authorised
professional. Heating circuit temperatures are not monitored
during measurement of emission. Faulty operation or
unsupervised operation of this function may result in
damages to the heating system.

07:07 Legionella
protection (time)
Setting range: 00:00 … 23:00 o'clock X3
Factory setting: 02:00 o'clock
Function:
This value is used to set the time at which the legionella
protection function is to be started on the set weekday (see
07:06).
07:08 Legionella
Protection
(temperature)
Setting range: 10…65 °C X3
Factory setting: 60 °C
Function:
This value is used to specify setpoint temperature for legionella
protection function (see 07:06).
07:09 Switching
differential
Setting range: 2 … 20K X3
Factory setting: 5K
Function:
To prevent frequent loading of the DHW tank, the DHW setpoint
temperature is adjusted under consideration of a switching
differential.
• Activation of DHW loading at setpoint temperature – ½
switching differential
• Termination of DHW loading at setpoint temperature + ½
switching differential
07:10 Maximum
temperature limit
Setting range: 20 … 80 °C X3
Factory setting: 65 °C
Function:
This function serves as protection of the DHW tank.
Irrespective of parameter settings 07:02, 07:03 and 07:08, at
most the set value will be adjusted.
If exceeded, the charging pump is switched off immediately.
ATTENTION: Observe operating instructions of DHW tank
before making any changes. Excessive maximum temperatures
can result in damages on DHW tank.
07:11 Exceeded load
temperature
Setting range: 0 … 20K X3
Factory setting: 10K
Function:
This function determines the lead value for the tank load
temperature through the heat generator, compared to the set
DHW setpoint.
Heat generator setpoint = DHW setpoint +
Exceeded load temperature
