(walls have no storage effect) the delay should be set
(0 hrs.).
SLOPE OFFSET
(heating slope distance)
The HS temperature that is required for a mixer circuit is
calculated by adding the calculated temperature setting for
the heating circuit flow to the heating curve distance. The
heating curve distance compensates for sensor tolerances
and heat loss up to the mixer.
B-HEAT SINK
(circuit enable)
00 => OFF
01 => The heating circuit can be used by higher-order
functions (e.g. cooling function of a heat generator to
protect from overheating; heat removal during service
mode) as a heat sink/consumer. The heating circuit is
heated at the maximum flow temperature setting for the
duration of the function.

Heat circuit control
Weather-dependent control
The HS or flow temperature is determined via the set heat
slope to suit the measured outside temperature in such a
way that the set value for the room is approximately set if
the heating system is configured correctly.
=> Exact setting of the heat slope is extremely important
for weather-dependent control.
The circulation pump is controlled weather-dependently.
The circulation pump is switched on if there is a heating
demand and in Frost-protection mode.
Room sensor influence
The current room temperature can be included in
computation of the required flow temperature via a present
room temperature sensor.
The influence factor (parameter list) can be set between 0
(fully weather-dependent regulation) and 20 (room
temperature regulation with minimal outdoor temperature
influence). Position "----" deactivates room temperature
control. Positions "----" and "0" indicate differences for
demand-dependent circulation pump control.
