Settings description
dTonDHW -
temperature difference between T1
( T3 in scheme H ) and T2 ( T3 in scheme E )
that will the collector pump P1 or P2 at
100% capacity.
dToffDHW - temperature difference between T1
( T3 in scheme H ) and T2 ( T3 in scheme E ),
at which the pump will work with minimal
capacity
Pmin . Below this value, the
collector pump is stopped. It will be restated
when
dTonDHW value is reached .
dTonPOOL
–
in schemes with pool system,
temperature difference between T1 and T3
(for scheme F ) and T1 and T2 (for scheme
I ), which starts P1 pump at 100% capacity.
dToffPOOL - temperature difference between T1
and T3 (for scheme F ) and T1 and T2 (for
scheme I ), at which the pump will work with
minimal capacity Pmin. Below this value, the
collector pump is stopped. It will be restated
when
dTonPOOL value is reached.
TCOLmin - minimal collector temperature, which
must be reached to allow reservoir loading. If
the collector temperature has not reached
this setting value, despite that loading
conditions are met (resulting e.g. from
reaching
dTon ) the controller would not start
the collector pump.
The collector pump will be started only below
dToffDHW or dToffPOOL (depending on
scheme).
TCOLcr
–
collector critical temperature.
Temperature which regardless of reaching
reservoir preset (
TsDHW ) or pool preset
( TsPOOL ) will start the collector pump at
100% capacity in order to discharge heat
from the collector. It will be stopped when
the collector temperature drops below
TCOLcr-HPx (where x means the number of
collector pump: 1 or 2 ). If AlarmTCOLcr
setting has YES value , the unit displays
alarm on exceeding critical collector
temperature. This alarm allows starting
collector pump, only when the system with
DHW reservoir is not in condition of
exceeded reservoir maximal temperature
TDHWmax alarm .
TCOLmax
–
reaching this collector temperature
will stop the collector pump. The controller
reports alarm. The collector pump may be
started only when the collector temperature
drops below the temperature difference
TCOLmax-HPx .
The controller dynamically limits minimal
value of
TCOLmax setting and maximal
value of TCOLcr setting, so that set values
give interval between TCOLcr and
TCOLmax
not lesser than 30°C. This
protects from impulse increase of the
collector temperature when the collector
pump is started, after
TCOLcr is reached.
To set higher TCOLcr than allowed by the
controller, increase TCOLmax value, so
that the interval condition of 30°C is
maintained.
TDHWmax
- DHW reservoir maximal
temperature that stops collector pump and
disables further loading of the reservoir.
Alarm on exceeding DHW reservoir maximum
temperature is displayed. This alarm has
higher priority than alarm on
TCOLcr and
despite the alarm on collector critical
temperature; the controller will disable
starting the collector pump for the reservoir.
Alarm will be stopped and the pump start
released, when the reservoir temperature
drops below
TDHWmax-HPx .
Pmin
–
minimal capacity of the collector pump
reached if the difference between collector
and
reservoir temperatures drops to
dToffDHW or dToffPOOL value (depending
on scheme).
