Description
Select control algorithm.
For efficient temperature control one can select between three control algorithms
and an optimized actuator control. For optimized actuator control see next parame-
ter description P-66.
The following control algorithms can be selected: On/Off-control, PWM control for
heat pump in combination with surface heating with high inertia (slow systems) and
PWM control for surface heating with medium inertia (medium-lag systems) e.g.
convection with wall heating. To save energy the pump is released 2 minutes after
demand detection.

Options:

0: On/Off-Control
The heating will be switched on when the deviation between actual value and
setpoint is larger than 0,5 K. The heating will be switched off when the devia-
tion between actual value and setpoint is smaller than 0,5 K. On/Off-control is
ideal for floor heating systems with higher supply water temperatures. The af-
ter run time of the pump control is 5 minutes.
–
1: PWM-control with a period of 20 minutes.
This control mode is ideal for floor heating in combination with a heat pump
or with low supply water temperature. The after run time of the pump control
is 20 minutes.
–
2: PWM-control with a period of 12 minutes.
This control mode is ideal for wall heating and low supply water tempera-
tures. The after run time of the pump control is 12 minutes.
