6.4.0 To control two different Set points and how to define = DUO SET
The firmware in the EEPROM allows the usage of two different Set points. This with one sensor, with two of a kind or differ-
ent sensors (i.e. Temperature sensor and pressure transducer).
.
6.4.1 Window to set „DUO SET“
After your decision to use 2 sensors (Probes) follow option are open to be set.
Example: Pressure
Example input control parameter for DUO - SET
As before you can configure the control parameter for each Sensor in the subdirectory “REGULATION”
6.4.2 Sensors/Pressure transducer 1 or 2 Set points (DUO-SET)
Each sensor input can be defined separate according to the different Probes (Example)
Sensor 1 (P1)or (S1): Pressure via pressure transmitter, Sensor 2 (P2) or(S2): Temperature via temperature sensors NTC
Attention: Do not forget to place the correct jumper according to the sensor
6.
4.3 Wiring and placing jumpers for 2 set point but one sensor only
Attention: Bypass connection has to be made potential free (no voltage)
Depending to the sensor input Jumper have to be placed. Please consider for 1 sensor with 2 set points with open Bypass (SET1) control is fixed by set point S1.
With closed Bypass (SET2) control is taken over by set point 2

PROBES FUNCtion
INDEPENDANT
Ú
NORMAL
A „normal“control between both sensors
will take place. In function “Chiller” the
highest value of both sensor will control the
output of the ADR. In function “Heatpump”
the lowest value of both sensors controls
the output.
INDEPENDANT
The firmware offers for each sensor a
window for an individual programming of
each probe. No o matter if it is for tempera-
ture , pressure, external voltage or chiller
and heatpump
Same windows also available for Sensor (Probes)2
P1 = Sensor 1, P2 = Snesor 2
