All*
CO1 > F12 - 1: Three-step control
Function block parameters:
KP (gain): 0.1 to 50.0 (2.0)
Tn (reset time): 1 to 999 s (120 s)
TV (derivative-action time): 0 to 999 s (0 s)
TY (valve transit time): 15, …, 240 s (120 s)
CO1 > F12 - 0: On/off control

for OPEN signal
0
All*
CO1 > F13 - 1: only with CO1 > F12 - 1
Function block parameters:
Max. system deviation: 3.0 to 10.0 °C (3.0 °C)

CO1 > F14 - 1: FG1 has no function
Select:
BI = 1, BI = 0 (BI = 1)

Demand
processing in
HC1
0
All*
How the demand is processed in HC1 depends on the configuration of
CO1 -> F16, CO1 > F17 and CO7 > F15.

10 V
Input terminals

0
All*
CO1 > F16 - 1: only with CO1 > F15 - 1 and CO1 > F17 - 0
Function block parameters:
Lower transmission range: 0 to 150 °C (0 °C)
Upper transmission range: 0 to 150 °C (120 °C)
The standardized signal output (terminals 11/12) is not available anymore
as a control output.

0
All*
CO1 > F18 - 1: the standardized signal output (terminals 11/12) is not avail-
able anymore as a control output. The maximum flow set point (with boost, if
applicable) is demanded as a 0 to 10 V signal at the standardized signal out-
put.
Function block parameters:
Lower transmission range: 0.0 to 150.0 °C (0.0 °C)
Upper transmission range: 0.0 to 150.0 °C (120.0 °C)
Boost flow temperature demand: 0 to 30.0 °C (0 °C)

insufficient heat
supply
0
All
CO1 > F20 - 1: Demand of an external heat source
