ROOM SENSOR FOR COOLING (EB15-BT74)
An extra room sensor for cooling connects to the indoor
module to determine better when it is time to switch
between cooling and heating operation.
Place the extra room sensor in a neutral position in the
room where the set temperature is required. It is import-
ant that the room sensor is not obstructed from meas-
uring the correct room temperature, for example by
being located in a recess, between shelves, behind a
curtain, above or close to a heat source, in a draught
from an external door or in direct sunlight. Closed radi-
ator thermostats can also cause problems.
Select one of the inputs AUX 1-9 on terminal block AA2-
X28:3-11.
Connect earth to one of the inputs on the earth terminal
block AA2-X29:1-12.
The relevant AUX input is selected in menu 7.4
