WE Anl Function block parameters / Range of values (default)
1 All CO-SYS -> F01 - 1: Return flow temperature limitation active;
Function block parameter:
Limiting factor / 0.1 to 10.0 (1.0)
Function block cannot be selected if CO2 -> F08 - 1
1 All CO-SYS -> F02 - 1: Pt1000 sensors
CO-SYS -> F02 - 0: PTC sensors
1 All CO-SYS -> F03 - 1: Automatic changeover
0 All CO-SYS -> F04 - 1: Manual level locked;
automatic mode applies in switch positions –, 0, +
1 All CO-SYS -> F05 - 1: Three-step control
Function block parameters:
K (proportional gain) / 0.1 to 50 (2.0)
P
T (reset time) / 0 to 999 sec (120 sec)
N
T (valve transit time) / 10 to 240 sec (45 sec)
Y
CO-SYS -> F05 - 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)
0 All CO-SYS -> F06 - 1 only with CO-SYS -> F05 - 1
Function block parameter:
Max. deviation / 2 to 10 °C (2 °C)
0 All CO-SYS -> F07 - 1 only with CO-SYS -> F05 - 1;
continuous signal only for actuator with limit switch control
0 All CO-SYS -> F08 - 1: Measured values of all connected sensors can
be calibrated
0 All CO-SYS -> F09 - 1: All parameters are reset to their default
values (WE)
