Connecting sensors
Connect the sensor(s) to
terminal X6 on input
board(AA3) according
to the instructions be-
low.
Outside sensor
Install the outdoor tem-
perature sensor (BT1) in
the shade on a wall fa-
cing north or north-
west, so it is unaffected
by the morning sun for
example.
Connect the sensor to terminal block X6:1 and X6:2 on
the input board (AA3). Use a twin core cable of at least
0.5 mm² cable area.
If a conduit is used it must be sealed to prevent condens-
ation in the sensor capsule.
F1145
External
Temperature sensor, hot water charging
The temperature sensor, hot water charging (BT6) is
placed in the submerged tube on the water heater.
Connect the sensor to terminal block X6:7 and X6:8 on
the input card (AA3). Use a 2 core cable of at least 0.5
mm² cable area.
Hot water charging is activated in menu 5.2 or in the
start guide.

Temperature sensor, hot water top
A temperature sensor for hot water top (BT7) can be
connected to F1145 via soft inputs for showing the water
temperature at the top of the tank.
See page 27 for connecting the sensor.

Temperature sensor, external flow line
If temperature sensor, external flow line (BT25) needs
to be used, connect it to terminal block X6:5 and X6:6
on the input card (AA3). Use a 2 core cable of at least
0.5 mm² cable area.

Temperature sensor, external return line
If temperature sensor, external return line (BT71) needs
to be used, connect it to one of the AUX inputs on the
input board (AA3). Use a 2 core cable of at least 0.5 mm²
cable area.

Room sensor
F1145 is supplied with a room sensor enclosed (BT50).
The room sensor has up to three functions:
1. Show current room temperature in F1145's display.
2. Option of changing the room temperature in °C.
3. Makes it possible to change/stabilise the room
temperature.
Install the sensor in a neutral position where the set
temperature is required. A suitable location is on a free
inner wall in a hall approx. 1.5 m above the floor. It is
important that the sensor is not obstructed from meas-
uring the correct room temperature by being located,
for example, in a recess, between shelves, behind a cur-
tain, above or close to a heat source, in a draft from an
external door or in direct sunlight. Closed radiator ther-
mostats can also cause problems.
