after time set on parameter Pr27.
Pay attention as the three-way valve exchange temperature also varies when varying "SET SANI"
temperature.
Example:
WORK POWER: SANI
SET SANI = 70°C
Pr26 = 10°C
Pr27 = 60”
The valve opens in pellet thermo stove DHW circuit after 60" from reaching 61°C.
It closes after 60" if temperature drops below 60°C (at 59°C).
Pr26 PARAMETER NOT USED
The parameter is not used in some products.
Pr27 Three-way motorised valve change-over delay
Allows setting time after which three-way motorised valve change-over happens if the conditions on
parameters Pr25 and Pr26 exist. The parameter is not normally modified. To avoid its continuous three-way
valve exchanges, jeopardising its duration, it is advised not to excessively decrease this value.
Pr27 PARAMETER NOT USED
The parameter is not used in some products.
Pr28 Flue gas intake device switch-off threshold (in stand-by switch-off phase)
Only valid with automatic switch-off “STOP FIRE”, this parameter allows setting the flue gas temperature
minimum threshold below which the flue gas intake devices switches off. The parameter is not normally
modified.
Pr45 Screw feed motor reducer ON time in pre-load phase
Allows setting motor reducer ignition time during initial pre-load phase in ignition. This phase is part of the
entire ignition phase “LOAD PELL”. The motor reducer remains continuously on during this phase to allow
loading sufficient pellet to cover the ignition resistance. If necessary, this parameter can be increased or
decreased. The pellet must not excessively cover resistance during pre-load to avoid "popping" effect due to
excessive pellet during ignition phase; load depends on size of burnt pellet. Parameters Pr46 and Pr47 linked
to this parameter can be increased or decreased.
Pr46 Stand-by time after pre-load phase
Allows setting a time during which motor reducer remains off after initial pre-load phase. This parameter can
be increased or decreased to anticipate/delay change to subsequent intermittent pellet load phase during
“LOAD PELL” ignition phase.
Pr47 Flue gas intake device speed in pre-load phase
Allows setting flue gas intake device speed when equipment is working in pellet pre-load in brazier phase. If
using a difficult to burn "hard" (or dark) pellet, this parameter value can be increased. The same must also be
increased/decreased depending on flue draught.
Pr48 Wood flue gas minimum temperature to consider the wood side on
Allows setting the flue gas minimum temperature value (wood side) to consider wood combustion chamber on.
To avoid risk of not reaching sufficient flue gas temperature to consider wood side on, it is advised not to
excessively increase this parameter value; vice-versa, to avoid wood side being detected as on even if it is not
(or with coal on only), do not excessively decrease it. The parameter is not normally varied.
Pr49 Recirculation pump activation threshold
Allows setting the recirculation pump start temperature. The parameter is not normally modified.
