Room sensor BT50
Connected to AA3-X6:3-4.
When the room sensor is connected the temperatures
are displayed in the main menu. To affect the room
temperature, it must be activated in menu 1.9.4. The
size of the room temperature sensor influence is de-
termined by the set factor.
The actual value of the flow line is changed by moving
the offset:
(selected - current room temp.) x set factor = changing
curve offset

Cooling
Active cooling 4-pipe (ACS310)
Active cooling is produced by the air/water heat pump.
The accessory can control one cooling-charge pump
(-EQ1-GP12) and one cooling reversing valve (EQ1-
QN12), and one cooling circulation pump (-GP13) using
–BT64. An operating mode room sensor –BT74 can be
connected to the intended location on the main
product.
The cooling function is activated by filtered outdoor
temperature (filtration time can be set) and any room
sensors.
BT64 used for actual value during cooling operation.
The set point value is determined by a straight line
between set supply temperature at +20 °C and 40 °C
in outdoor temperature. Cooling DM is calculated for
start and stop of active cooling operation.
Cooling circulation pump (-GP13) is active when cooling
is permitted.
Cooling charge pump (-EQ1-GP12) is active when
cooling is produced and controls according to the
graph below.
Scheduling
If scheduled times overlap each other with different
adjustments a red exclamation mark is displayed to the

Heating
Heating can be scheduled with three periods for each
climate system. Changing the set point value for the
room temperature sensor or changing the curve offset
is optional.
Holiday
Holidays can be scheduled with a start date and a stop
date. Changing the set point value for the room tem-
perature sensor or changing the curve offset is select-
able and for hot water Economy, Normal, Lux and Off
can be selected.
