∆T (ºC) = Difference between the maximum flow temperature and the
minimum temperature for a radiator's heat emission (30ºC) or underfloor
heating (20ºC)
T = Room temperature
Room
T = Outside temperature
Outside
Selection example:
Evaluate the Slope for an installation based on:
Maximum water flow temperature = 80ºC
Room temperature = 20ºC
Outside temperature = -5ºC
Slope = (80 - 30) / (20 - (-5)) = 50 / 25 = 2
Note: In underfloor heating systems, the slope ranges between 0.5 and 1.
The relationship between the outside temperature and the water flow
temperature can be established at any point in the slope.

The factory-set slope in each heating circuit is 2.5
ADAPTATION
Automatic slope adaptation.
It enables the heating controller to automatically adjust the system slope in
accordance with its operating development.
This feature is active only if an outdoor sensor AF has been connected.
00=OFF
01=ON
ROOMS INFL
Room temperature influence.
The boiler temperature increases up to the selected value when the room
temperature drops below the value set in 1 K.
00: Operation according to the outside temperature
20: Operation according to the room temperature
CALIB T-AMB
Correction of room sensor.
The room sensor reading can be changed under this parameter if the
sensor is not measuring correctly.
OPTIM HEAT
Optimization.
00=OFF
01= The heating controller brings forward system operation ahead of the
pre-set programme according to the outside temperature.
02= The heating controller brings forward system operation ahead of the
pre-set programme according to the room temperature.
MAX OPT-TIME
Maximum optimization time.
This feature will not operate if the OPTIMIZATION parameter has been
configured under 01 or 02.
System operation is brought forward the time set under this parameter at
the most.
ECONO OPTI
Reduced optimization time.
Boiler switch-off is brought forward the time set under this parameter at
the most in relation to the time set by the programme.
