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.

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.

The heat pump operates without the sensor, but if one
wishes to read off the accommodation's indoor temper-
ature in F1145's display, the sensor must be installed.
Connect the room sensor to X6:3 and X6:4 on the input
board (AA3).
If the sensor is to be used to change the room temperat-
ure in °C and/or to change/stabilise the room temperat-
ure, the sensor must be activated in menu 1.9.4.
If the room sensor is used in a room with underfloor
heating, it should only have an indicatory function, not
control of the room temperature.

Caution
Changes of temperature in accommodation
take time. For example, short time periods in
combination with underfloor heating will not
give a noticeable difference in room temperat-
ure.
Connecting external energy meter
NOTE
Connection of external energy meter requires
version 35 or later on input board (AA3) as well
as "display version" 7113 or later.
Connect the energy meter(s) to terminal X22:1-3 and/or
