8.13 Connecting potentiometers for valve position input

The FG1 and FG2 inputs can be used to connect potentiometers, for example to input valve
positions when a resistance room sensor is not configured in the control circuit concerned.
The measured values (in the measuring ranges from 0 to 2000 Ω) do not appear on the con-
troller display. They are only available as Modbus data points.
Functions
Room sensor RF1, 2

8.14 Creep feed rate limitation with a binary input

It is possible to report to the controller when the creep feed rate has fallen below a certain
level by using a limit switch of the primary valve connected to the terminals 04/12 or to in-
put RüF1. Either the open (BI = 0) or closed binary input (BI = 1) can be configured at termi-
nals 04/12 to indicate that the creep feed rate has fallen below a certain level. Only the
closed binary input at RüF1 can be processed. Shortly after the alert, the controller closes the
valve HC1. As soon as the flow temperature falls below the set point by more than 5 °C after
the valve has been closed, control operation is started again.
Functions
Creep feed rate limitation

8.15 Locking manual level

To protect the heating system, this function can be used to lock the manual level. When this
function has been activated, automatic mode is started when the rotary switch is set to in au-
tomatic mode.
