Red Hydro stoves and boilers - pump operation parameters

This article relates to those boilers and stoves in the Red 365 range that have the Systen Configuration option (1-5), namely:

• Compact
• Primula
• Orchedia
• Gardenia
• Margherita
• Logika

CONF.1
DEFAULT : Eco OFF

Active Phase :         Pump ON    if T H2O> Ton pump
                       Pump OFF   if T H2O< Ton pump - hysteresis pump

No Active Phases :          Pump ON  for t Off Pump ( 10 min)    if T H2O> Ton pump .  Then check temp and...if T H2O > Set H2O  - T hysteresis pump .....Pump ON
                       If during  t Off Pump ( 10 min) T H2O < Ton pump- T hysteresis ...Pump OFF   and reset the  t Off Pump ( 10 min)


Thermostat management :
T Amb: OK when the T Set Amb is OK
T Amb: NO  when the T Set Amb is 0.5°Clower than SET

Default Auto Eco Off
Summer / Winter function not active in this conf.

CONF.2



Summer / Winter function active in this conf.

Summer:
Auto Eco always active  ( not possible to deactivate it from control panel )
Thermostat is not considered .



WINTER :
Active Phase :         Pump ON    if T H2O> Ton pump
                       Pump OFF   if T H2O< Ton pump - hysteresis pump

No Active Phases :          Pump ON  for t Off Pump ( 10 min)    if T H2O> Ton pump .  Then check temp and...if T H2O > Set H2O  - T hysteresis pump .....Pump ON
                       If during  t Off Pump ( 10 min) T H2O < Ton pump- T hysteresis ...Pump OFF   and reset the  t Off Pump ( 10 min)


SUMMER:
T set H2o - automatically set to T set H20  for DHW
Auto Eco always ON
Active Phase :         Pump ON    if T H2O> Ton pump
                       Pump OFF   if T H2O< Ton pump - hysteresis pump

No Active Phases :          Pump ON  for t Off Pump ( 10 min)    if T H2O> Ton pump .  Then check temp and...if T H2O > Set H2O ( DHW) - T hysteresis pump .....Pump ON
                       If during  t Off Pump ( 10 min) T H2O < Ton pump- T hysteresis ...Pump OFF   and reset the  t Off Pump ( 10 min)

Thermostat management :
SUMMER :         The 3 way valve always towards the DHW circuit .
               Auto Eco ON ( not possible to deactivate it )
               The ambiance thermostat is not considered.

WINTER:         Auto Eco : OFF  ( but it is possible to activate it)
               IF Set H2o ( heating) power goes to 1 but the Auto Eco CountDown  starts only IF Tamb is OK.
               With boiler in Auto Eco it restarts quickly ( delay 10 sec) when the thermostat demands power


BOTH : Water Flow sensor ( Or Thermostat with the water cylinder) to connect in the motherboard in AUX IN position

CONF.3
Summer / Winter function active in this conf

Summer:
Auto Eco always active  ( not possible to deactivate it from control panel )
Thermostat is not considered .

WINTER :
Active Phase :

T Set Cylinder : NOT OK   >>>> 3 way valve on DHW position  >>>         pump is ON only when T H2o > T cylinder +3 degrees  
                                                                                       pump is OFF when T H2o <  T cylinder +1,5 degrees  


T Cylinder  is OK when it is T Set Cylinder + 2,5°C
T Cylinder  is NOT OK when it is T Set Cylinder +0,5°C  >>>>>>                Tset H20 become the T set DHW

IF T Cylinder  is OK>>>>  3 way valve on Heating position >>>>                pump is ON only when T H2o > Ton pump
                                                                                       pump is OFF only when T H2o < Ton pump



No Active Phases :
Pump ON  for t Off Pump ( 10 min)    if T H2O> Ton pump .  Then check temp and...if T H2O > Set H2O ( DHW) - T hysteresis pump .....Pump ON
If during  t Off Pump ( 10 min) T H2O < Ton pump- T hysteresis ...Pump OFF   and reset the  t Off Pump ( 10 min)


Thermostat / Probes management :
NTC probe on 3-4  of the back connector
Water Flow sensor is not heard in this conf.

SUMMER:
pump is ON only when T H2o > T cylinder +3 degrees  
pump is OFF when T H2o <  T cylinder +1,5 degrees  

Eco Mode is always ON and  IF Tset Cylinder  is OK  >>>>> Boiler Shutdown  for Eco  Mode
If Tset H20 is OK  >>>>   power goes to 1

CONF.4

Installer should set the Ton Pump and the T set H20  at an higher value compared to the setting in the Buffer Thermostat.

Thermostat : Always ON
NTC probe: Not Heard
Auto Eco : Always ON
T set H2o : Automatically set at 80°C
Water Flow sensor : Not heard
3 way valve always directed towards the heating position
When the Buffer Thermostat is OK  >>>>  the Boiler Starts the Auto Eco procedure  to shutdown (even if Tset H20 is not OK)



Pump Management :

Active Phase :         Pump ON    if T H2O> Ton pump
                       Pump OFF   if T H2O< Ton pump - hysteresis pump
