COMFORT with AUTO
ADAPT
COMFORT BA PM and BXA PM models have the
following operation modes:
•
AUTO
ADAPT
mode
• temperature control mode
• continuous 100 % mode.
AUTO
ADAPT
mode
The AUTO
ADAPT
function adapts the operating hours by
switching on and off according to the tapping pattern of
the users. This means that the pump provides maximum
comfort and saves energy at the same time.
Energy-saving
The AUTO
ADAPT
function saves energy in two ways:
• Electrical energy consumption of the pump
• Heat energy consumption of the domestic hot-water
system.
The AUTO
ADAPT
function automatically adjusts the
number of operating hours, based on the hot-water
consumption in the given system.
The AUTO
ADAPT
function requires a temperature sensor
to be installed on the flow pipe 20 to 50 cm from the boiler
outlet. This sensor and the temperature sensor
incorporated in the pump detect when hot water is tapped.
The detected tapping events are logged and used to
predict the consumption pattern. The AUTO
ADAPT
function
automatically controls the on/off behaviour of the pump
according to this pattern. This ensures that the pump only
runs when necessary, which saves both heat energy and
electrical energy.
The pump needs two weeks to adapt when hot water is
tapped. This means that the pump starts up in
temperature mode the first two weeks even if you have
selected AUTO
ADAPT
.

AUTO
ADAPT
in heating systems regulated
with a thermostatic regulating valve
In systems including a thermostatic regulating valve,
choose a COMFORT pump without the AUTO
ADAPT
function.
Choosing a pump with AUTO
ADAPT
function will result in
two active regulating systems working separately, which is
not recommendable.
NOTE: If a pump with AUTO
ADAPT
function is installed in
a circulation system where the temperature of the
recirculated water is regulated by a thermostatic
regulating valve, we recommend that you open the
thermostatic regulating valve completely. This is done by
setting the valve to max., which deactivates its regulating
function.

Example of an application with thermostatic regulating
valve
Pos. Description
1 Thermostatic valve
Control function
The control function is a combination of three parameters:
• detection of hot-water consumption
• event log function (when the demand occurs)
• pump control.
Detection of hot-water consumption
The detection of hot-water consumption is done via the
temperature sensor installed in the flow pipe. The system
logs the tapping events. Temperature rise caused by the
pump operation is not registered in the event log.
