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.
Room sensor
F1155 is supplied with a room sensor enclosed (BT50).
The room sensor has a number of functions:
1.
Shows current room temperature in the display on
F1155.
2.
Option of changing the room temperature in °C.
3.
Provides the option of fine-tuning the room temper-
ature.
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 F1155'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 fine-tune the room temperature, 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" 7312 or later.
One or two energy meters (BE6, BE7) are connected to
terminal block X22 and/or X23 on input board (AA3).
