Introduction
Application
The controller and valve can be used where there are stringent
requirements to accurate temperature control in connection with
refrigeration.
E.g.:
• Cold room for fruits and food products
• Refrigerating systems
• Work premises in the food industry
• Process cooling of liquids
Advantages
• The temperature is kept within an accuracy of ±0.25°C or better
after a transient phenomenon
• The evaporator's temperature is kept as high as possible, so that
the air humidity is kept high and waste is limited
• A transient phenomenon can be controlled with the adaptive
function. Select either:
- Fast build-up where underswings are allowed
- Not quite so fast build-up where underswings are less pro-
nounced
- Build-up without underswings
• PID regulation
• p
0
limitation
Functions
• Modulating temperature control
• Digital ON/OFF input for start/stop of regulation ICS/PM or
forced closing of ICM
• Alarm if the set alarm limits are exceeded
• Relay output for fan
• Relay output for solenoid valves
• Analog input signal that can displace the temperature reference
• Analog Output signal corresponding to selecting temperature
as running display value. Please observe : Not possible if ICM is
selected as valve
Start/
stop
ICS or PM
