)

REMOTE

This option allows you to choose which sensor is used to 
control the heating system  

• 

r

:   The internal room sensor inside the thermostat, con-

trols the heating system 

• 

r

E

:  An external room sensor (connected to the floor 

sensor terminals) controls the heating system 

• 

r

F

:   The internal room sensor controls the heating 

system subject to maximum and minimum limits 
for floor temperature  The maximum temperature 
limit protects wooden floors from excessive heat  
The minimum temperature limit prevents the floor 
from becoming uncomfortably cold when heating is 
not needed, such as in a bathroom  Note that this 
function will increase energy consumption  Floor limit 
temperatures are set in the “FLLo, FLHi” settings  
(see page 26)

• 

C

:   The thermostat operates as a regulator and no sen-

sors are used  Note that floor protection is not active 
when using this application 

• 

F

:   The external floor sensor controls the heating system
