Setpoint shifting
The operator often wishes to adapt the condensing pressure or the outlet temperature to specific
operating conditions. The TCS.2 offers three options to choose from. These are described in detail
below. The selection is done in the Device settings -> Control (see chapter 4.2.4 “
.
Setpoint shifting via external standard signal
The setpoint shifting can take place via an analogue signal on input AI-3 for circuit 1 or on AI-4 for
circuit 2 (see also chapter 4.3.3 “
”).
The following standard signals are possible: 0-10 V, 2-10 V, 0-20 mA, 4-20 mA
This function is activated in the Device settings
-> Control (see chapter 4.2.4 “
.
As soon as a type of control has been selected,
the “Setpoint shifting” button in the “Setpoints”
menu has a blue background and can be
pressed. The user gets to the following settings
window: Picture 63.
The value edited here is added to the setpoint
if the analogue signal is 100%. Depending on
whether a condenser (as shown here Picture
64) or a dry cooler has been selected as the
heating system, both setpoints (NC - normal
c FC - free cooling or HR - heat
recovery) can have their own value for the
maximum setpoint shifting. However, both
setpoints react to only one analogue input (AI-
3 for circuit 1 and AI-4 for circuit 2).
“Setpoint“:
Set target temperature (25 °C)
“Shift value”:
Corresponds to the value of the analogue input (0-100%) of the maximum set
shift value (in the example Picture 64 dt 20 °C).
“Setpoint act.”: Addition of setpoint and shift value
Circuit 1: (25 + 10.7 °C = 35.7 °C)
Analogue input 3 (0-10 V) 5.3 V
