Connecting the operation modes
You can connect the 3 circulation operation modes with each other in order to adapt the
circulation to your needs. The following combinations are possible:
• Time control + temperature control: The temperature control is only active during the
determined time windows. The circulation pump is switched on and off by the conditions
of the temperature control.
• Temperature control + demand: The circulation is switched on on demand
(tap impulse). The circulation is switched off when the switch-off threshold temperature
is exceeded or after the end of the runtime. After that, the demand for a determinable
break is locked.
• Time control + demand: During the time windows, the circulation runs continuously.
Outside the time windows, the circulation starts on demand and stops after the end of
the runtime. After that, the demand for a determinable break is locked.
• Time control + temperature control + demand: The temperature control is only active
during the determined time windows. Outside the time windows on demand. When the
desired temperature is reached, the demand ends ahead of time. If it is reached, the
function is still locked by the demand for the determined break and can only be
activated if the break has ended.
