ROOM SENSOR
F1345 can be supplemented with a room sensor (BT50).
The room temperature sensor has up to three functions:
1.
Show current room temperature in the heat pump'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
curtain, above or close to a heat source, in a draft from
an external door or in direct sunlight. Closed radiator
thermostats can also cause problems.
F1345 operates without the sensor, but if you want to
read the home’s indoor temperature from the display,
the sensor must be installed. Connect the room sensor
to AA3-X6:3 and AA3-X6:4.
If the sensor is to be used to change the room temper-
ature in °C and/or to change/stabilise the room temper-
ature, 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 the accommodation
take time. For example, short periods of
change combined with underfloor heating will
not result in a noticeable difference in the room
temperature.
