General
This accessory is used when
F1145/F1245/F1345/F370/F470/F750/VVM500 is installed
in houses with up to four different climate systems that
require different flow line temperatures, for example, in
cases where the house has both a radiator system and
an under floor heating system.
The water flow in the climate systems together should
not exceed 1700 l/h.
Caution
Underfloor heating systems are normally
max
flow line temperature
set between 35 and 45
°C.
Check the max temperature for your floor with
your floor supplier.
Caution
If the room sensor is used in a room with under
floor heating it should only have an indicatory
function, not control of the room temperature.
