General Information
Drying period mode Off (Off/1/2/3)
Floor drying function for newly-built properties.
The function limits the calculation of primary flow
temperature (setpoint) for “Your home’s heating
installation” to the schedule below.
Mode 1
Floor drying function for 8 days.
1. The (setpoint) of the radiator system is set to 25ºC for
4 days.
2. On Days 5–8, the value set in “Floor function temp.
ºC” is used.
(From Day 9 onwards the value is calculated
automatically according to “Your home’s heating
installation”)
Mode 2
Floor drying function for 10 days + stepped increase
and decrease.
1. Stepped increase start: The (setpoint) of the
radiator system is set to 25ºC. The (setpoint) is
then raised by 5ºC each day until its (setpoint) is
equal to the “Floor function temp. ºC”.
The final step may be less than 5ºC.
3. Stepped decrease: After the stepped increase
and 10 days at an even temperature, the
temperature (setpoint) is reduced to 25ºC in daily
5ºC stages.
The final step may be less than 5ºC.
(Following the stepped decrease and one
day at the (setpoint) of 25ºC the value is calculated
automatically according to “Your home’s heating
installation”.)
Mode 3
In this mode, the function starts in Mode 1 and this is
then followed by Mode 2 and finally by “Your home’s
heating installation”.
