WE Anl Function block parameters / Range of values (default)
0 2, CO2 -> F08 - 1 only with CO2 -> F01 - 1 and CO-SYS -> F01 - 1
4*, 6
* In system Anl 4 only applicable when implemented as a
secondary system.
To do so, mount return flow sensor RüS in the primary circuit in
the heat exchanger of the storage tank charging system; the
sensor is not used for return flow temperature limitation!
0 4, 5* CO2 -> F09 - 1: Options:
Function block parameters:
Activate priority in case of deviation / 60 to 600 sec (300 sec)
Monitoring value / 20 to 90 °C (40 °C)
* Cannot be selected in Anl 5 if CO2 -> F13 - 1
1 2, 3 CO2 -> F10 - 1: 10 min of intermediate heating after 20 min;
only with CO2 -> F06 - 0
CO2 -> F10 - 0: Priority for DHW heating
1 5 CO2 -> F11 - 1: Three-step control
Function block parameters:
K (proportional gain) / 0.1 to 50.0 (2.0)
P
T (reset time) / 0 to 999 sec (120 sec)
N
T (valve transit time) / 10 to 240 sec (45 sec)
Y
CO2 -> F11 - 0: On/off control
Function block parameters:
Hysteresis / 2 to 10 °C (5 °C)
Min. ON time / 0 to 600 sec (120 sec)
Min. OFF time / 0 to 600 sec (120 sec)
Function block cannot be selected if:
CO2 -> F13 - 1 or CO2 -> F14 - 1
1 5 CO2 -> F12 - 1: Return flow temperature limitation in DHW circuit
active, only with CO2 -> F11 - 1 and CO2 -> F14 - 0
Function block parameter:
Limiting factor / 0.1 to 10 (1.0)
0 5 CO2 -> F13 - 1: On/off valve (controlled over outputs DHW +
and DHW –) and thermostat at input VS2; only with CO2 -> F11
- 0 and CO2 -> F14 - 0
Function block parameter:
Valve transit time / 10 to 240 sec (45 sec)
CO2 -> F13 - 0: Temperature valve (output DHW+) and
temperature sensor at input VS2
1 Reverse control
2 Set-back operation
