Parameter Meaning
SYSTEM CIRCUIT Indicates if the system shunt group must be controlled by a heat curve or by a constant temperature. Condi-
tions are that CONFIGURATION = TANK CONTROL and the external auxiliary heater is not configured.
Factory setting:
HEAT CURVE, range:
HEAT CURVE – CONSTANT TEMP - OPEN CIRCUIT.
At the selection OPEN CIRCUIT, the shunt outputs are not active, but the temperature for system supply is dis-
played 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: 30s, range: 10s – 99s
SYS.PUMP COOL Indicates whether the system's circulation pump must be used for cooling. Not displayed if
external auxiliary heater is selected.
Factory setting: ON, range:
– ON
DISTRIBUTION
CIRCUIT 1 - 2
Indicates if the distribution circuit must be controlled by a heat curve or by a constant temperature.
Factory setting:
HEAT CURVE, range:
HEAT CURVE – CONSTANT TEMP - OPEN CIRCUIT. At the selection OPEN CIRCUIT, the shunt outputs are not ac-
tive, but the temperature for the distribution circuit is displayed in the OP.DATA menu.
Open circuit cannot be used in connection with CONFIGURATION = TANK CONTROL or if external auxiliary heat-
er is configured.
The option (OFF) deactivates the distribution circuit function fully. The menu only appears if distribution cir-
cuit sensor is connected
SHUNT TIME DC1 - 2 Indicates shortest permitted time between control signals to the shunt.
Factory setting: 30s, range: 10s – 99s
DISTR. 1-2 P. COOL Indicates whether the circulation pump for distribution circuit must be used for cooling.
Factory setting: ON, range: – ON
HEAT STOP DEPEN.
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
POOL CIRCUIT Used to indicate where the reversing valve for pool is located. The system supply circuit cannot be used if exter-
nal auxiliary heater is configured.
Factory setting: SYSTEM SUPPLY, range: SYSTEM SUPPLY - DISTRIBUTION CIRCUIT 1 - DISTRIBUTION CIRCUIT 2
MAX TIME POOL determines the longest permitted pool heating time at non-integral controlled circuit.
Factory setting: 40M, range 1M – 210M
MAX TANK TEMP Maximum permitted temperature in the buffer tank. Fixed value 55°C is used if no external auxiliary heater is
configured. With an external auxiliary heater the temperature can be set between 55°C – 80°C.
Factory setting: 55°C, range: 55°C – 80°C
