9.2.2 Settings for operation modes 2.01 ... 2.05
2.01 Temperature control airconditioning and refrigeration
(preset set-point 20.0
°
C, P-band 5.0 K)
2.02 Temperature control depending on outdoor temperature
(preset set-point 5.0
° C, - P-band 20.0 K)
2.03 Temperature control with pre-programmed additional functions (heating, shutter, temperature monitor-
ing).
2.04 Temperature control with 2 sensors
Comparison with control to higher value
“ E2 Function ” set to comparison

. Display during
operation: “ Control value ”
Alternative: Average calculation of 2 measuring places “ E2 Function ” set to
|
3E
|
. Display during
operation: “ Average E1 / E2 ”
2.05 Temperature control with 2 sensors, regulation on difference temperature.
Display during operation:
“ Value of E1 - E2 ” in K, “ E1 ” = reference temperatur, “ E2 ” causes positiv (E2
< E1) or negative (E2 >E 1) difference.
