0.0
Optimised switch-on of the heating system (heating circuit 1)
This setting value enables the optimised switch-on of the heating system and simultaneously limits the
max. permissible warm-up time.
0,0 h
:
Optimised switch-on is disabled. The switching times of the time programs are
relevant for
operation.
> 0 h
:
Optimised switch-on enabled. The max. warm-up time corresponds to the set value.
(0.0...19.9) (h)

0.0
Optimised switch-on cycle of the heating system (heating circuit 1)
This setting value enables the optimised switch-off mode of the heating system and simultaneously limits
the max. permissible switch-off time.
0,0 h
:
Optimised switch-off is disabled. The switching times of the time programs for
or
are relevant.
> 0 h
:
Optimised switch-off enabled. The controller calculates the earliest possible time for
switching off (without significant loss of comfort).
(0.0...9.9) (h)

6.0
Control of circulation pump UP1 (heating circuit 1) for the change-over
→
according to time
program, without room-temperature sensor.
If no room-temperature sensor T
R1
is connected for heating circuit 1, the controller will use a model
temperature. After changing the operating mode from the
→
, circulation pump UP1 of heating
circuit 1 is switched off. UP1 is switched on again and heating is continued with the reduced setpoint as
soon as the calculated model room temperature has reached the reduced room-temperature setpoint
(PAR 2) or after the period set for this parameter has elapsed.
(0...19.9) (h)
(N.B.: When a room temperature sensor is connected, the heating remains switched off after a transi-
tion from
→
until the measured room-temperature value has reached the reduced room-
temperature setpoint (PAR 2).

Adaptation of building-cooling time constant (with room-temperature sensor T

)
–1
=
Disabled
> = 0
=
Adaptation of building-cooling time constant enabled, and display of number of
adaptation steps. The adaptation steps have more effect at the beginning
(= low numerical value); this is successively reduced as the number of steps increases.
