5.4.4 Setpoint Shift
An optimally calculated setpoint for the operation can result in reduction of the energy costs. The determination
of the t
0
setpoint (setpoint shift) for the low-pressure control can be performed using the following operations in
menu 3-2-1-2:
room temperature sensor
demand-dependent using case controller (consumer)
external signal via CAN bus
external signal via analogue input
a humidity sensor
5.4.4.1 Setpoint Shift via Room Temperature
The determination of the t
0
setpoint is performed depending on the room temperature (t
0
setpoint shift via room
temperature, see menu 3-2-1-2). The room temperature is provided here either by a Pt1000 temperature
sensor that is connected directly to the analogue input (terminals 5/6/7/8) of the pack controller or provided via
the CAN bus from another pack controller in the E*LDS system, see chapter
Ambient Data for Setpoint
Switching .
t

= t
0
setpoint
t
0_max
= maximum t

setpoint
t
0_min
= minimum t
0
setpoint
t
r
= current room temperature
t
r_max
= maximum room temperature for setpoint shift
t
r_min
= minimum room temperature for setpoint shift
For a room temperature t
r
> t
r_max
or t
r
< t
r_min
the setpoint t
0
is specified as constant as follows:
for t < t
r_min
t
0
= t
0_max
for t > t
r_max
t
0 = t0_min
If the room temperature sensor or the humidity sensor for the setpoint shift is not connected to the
controller, these can be made available as required from another controller, see chapter
Ambient Data
for Setpoint Switching .
