Parameter
Meaning
SYSTEM CIRCUIT
Indicates if the system shunt group must be controlled by a heat curve or by a con-
stant temperature. Conditions are that CONFIGURATION = TANK CONTROL and the
external auxiliary heater is not configured.
Factory setting: HEAT CURVE, range: HEAT CURVE – CONSTANT TEMP - OPEN CIR-
CUIT. At the selection OPEN CIRCUIT, the shunt outputs are not active, but the tem-
perature for system supply is displayed in the OP.DATA menu. The menu only
appears if external auxiliary heater is not selected.
SHUNT TIME SYS.
Indicates shortest permitted time between control signals to the system shunt.
Factory setting: 60S, range: 10S – 99S
SYS.PUMP COOL
Indicates whether the system's circulation pump must be used for cooling. Not dis-
played if external auxiliary heater is selected.
Factory setting: ON, range:
– ON
DISTRIBUTION CIRCUIT 1 - 2
Indicates if the shunt group must be controlled by a heat curve or by a constant
temperature.
Factory setting: HEAT CURVE, range: HEAT CURVE – CONSTANT TEMP - OPEN CIR-
CUIT. At the selection OPEN CIRCUIT, the shunt outputs are not active, but the tem-
perature for shunt group is displayed in the OP.DATA menu.
Open circuit cannot be used in connection with CONFIGURATION = TANK CON-
TROL or if external auxiliary heater is configured. The option (OFF) deactivates
the shunt group function fully. The menu only appears if SHUNT GROUP sensor is
connected
SHUNT TIME DC1 - 2
Indicates shortest permitted time between control signals to the shunt.
Factory setting: 60S, range: 10S – 99S
DISTR. 2 PUMP COOL
Indicates whether the circulation pump for shunt group must be used for cooling.
Factory setting: ON, range:
– ON
HEAT STOP DEPENDENT.
indicates if heating the buffer tank is to be influenced by HEAT STOP. A condition is
that CONFIGURATION = TANK CONTROL.
Factory setting: YES, range: NO – YES
