Local sensor (se.L) refers to the ROOM or FLOOR sensor.
The device will get the room’s temperature from the room
or oor temp sensor based on your conguration of P-06.
If you choose the remote sensor (se.r), the device will get
room temperature from the gateway (e.g a second device
in your smart home system which reports temperature).
Use the remote sensor in the case where you have the
thermostat installed outside the room you want to heat.
(e.g. when the oor heating does not provide a oor
sensor probe).
Fallback solution
If the remote sensor doesn’t receive the room
temperature from the gateway within 20 minutes, the
thermostat will use a fallback solution
= 1 MIN ON - 4 MIN OFF (Thermostat will be set to 20%
ON - 80% OFF)
The fallback solution will be executed until a remote
sensor reports room temperature.
P-18 Home interface temperature display
Select which temperature to show on display. You can
choose set temperature, room temperature or oor
temperature.

display will show the set temperature for 10 seconds.

P-19 Set local schedule temperatures
Select *Auto mode when using local schedules.
A local schedule is only active when the thermostat
is in Auto mode.
When using the thermostat without connecting it to a

noon, afternoon and night temperature to optimize your
heating schedule and energy use.
