2)
If there is a “disposable”
CO installation in the
house, i.e. water from the
radiator is cooled down
and drained into the pipe
feeding hot water into the
next radiator, and then, upon going through all radiators in an loop, it is drained to
the boiler, the most economical setpoint is the lower setpoint from characteristics
of proportional pressure PP
2
. The higher setpoint can also be selected from the
characteristics of proportional pressure PP
2.
3) In case of floor heating, an optimal choice is an AUTO or a potentially higher
setpoint CP
1
, or lower CP
2
from the characteristics of constant pressure.
NIGHT MODE:
Night pump operation mode can be used only when:
-
CO installation with a furnace must be equipped with automatic
temperature regulation of a heating medium - that is, it must have capacity
to work in the night mode.
-
The pump must be installed on the pipe exiting the furnace. The night mode
does not operate on the entering pipe.
-
CO installation with small volume of heating medium cannot cooperate
with a pump operating in a night mode.
The principle of NIGHT MODE operation:
The use of the night mode switch will cause the automatic system of the pump will
monitor the temperature changes in flowing water. If the temperature signalling
unit detects temperature lowering of at least 0.1
O
C/min in the period of about 2
hours, it will result in automatic switch the pump into night operation mode. In
case of increase in temperature of the heating medium of about 10
O
C, the pump
will automatically switch back into standard operation mode.
Night operation mode can only be launched in the automatic mode of
parameter selection of pump operation for installation parameters - AUTO
mode.
Power cut results in deactivation of the night mode. Upon restoration of power it is
necessary to switch the night mode on by pressing the proper button.
START-UP, OPERATION:
The pump can be started after the installation is filled with water.
CAUTION Attention must be paid to installation tightness, i.e. if the pump is
not flooded with dropping or leaking water from the installation.
Pump flooding with water coming from the exterior can result in device
destruction. In such a case, only paid repair is available.
