Demand
The allocated FS08 fl ow switch is monitored for circuit continuity. If circuit conti-
nuity is detected at the fl ow switch, the relay switches on for the adjusted runtime.
After the runtime has ended, the relay is switched off. During the adjusted break
time, the relay remains switched off even if continuity is detected at the fl ow switch.
Note:
If the fl ow switch is connected to the input S1 … S8, continuity must be
detected for at least 5 s for the controller to react, 1s if the fl ow switch
is connected to an impulse input.
Demand + Timer
The relay operates when the switch-on conditions of both above mentioned var-
iants are fulfi lled.
When the Timer, Therm. + Timer or Timer variant is activated, a
timer is indicated in which time frames for the function can be adjusted.
Note:
For information on timer adjustment see page 11.

* When a heating circuit has been activated, this adjustment is determined by the corre-
sponding parameter in the heating circuit menu.
The Return preheating function can be used for transferring heat from a heat
source to the heating circuit return.
The allocated relay is energised when both switch-on conditions are fulfi lled:
• the temperature difference between the allocated sensors has exceeded the
switch-on temperature difference
• the temperature at the outdoor temperature sensor has fallen below the
adjusted outdoor temperature
With the summer switch-off option, the return preheating can be suppressed out-
side the heating period.
