PUFFER MANAGEMENT WITH TWO PROBES, HIGH PUFFER PROBE AND LOW PUFFER PROBE
It is recommended to tap the supply water of the heating system from the Puffer at a height higher than or
equal to the Puffer S2 probe.
The Puffer High (S2) probe was previously connected and configured in IN 3 (clamps 35-36). At this point it
will be necessary to connect the Low Puffer Probe (S3) in Input 8(IN8, clamps 48 –49) and through the
System –Settings menu, set parameter P71 to 23.
Now through the User’s Menu, Heating managing it will be possible to set the desired temperature of both
probes.
Probe operation logic: The boiler passes into the Stan-by state when both probes (S2 and S3) are satisfied
and therefore both Puffer Probe thermostats (Low and high) have reached the temperature set in the User’s
Menu – Heating Management.
The boiler will exit the Stand-by state and then restart heating if Puffer Probe High (S2) temperature is < of
the Puffer High Probe Thermostat –Ih58 -1.
Example:
Puffer High Probe Thermostat (S2) = 50° (setting adjustable via user menu –Heating Management)
Ih58 = Puffer Thermostat Hysteresis S2 = 8° (Default setting –adjustable via System Menu –Thermostats
Puffer Low Probe Thermostat (S3) = 70° (adjustable setting via User Menu –Heating Management)
Puffer High Probe
Thermostat (S2 = 50°)
Puffer Low Probe
Thermostat (S3 = 70°)
