3.2.5 The Economy Circuit
Only for the sensoric heating devices equipped with
the control device 1563
The control device can be operated in the economy mode
as an alternative to normal functioning. The setting
temperatures of the water circuit will be kept at a lower
temperature in the economy mode. The fuel consumption
can be reduced at low heat requirement (for instance
while keeping warm) due to less radiation loss resulting
from this.
