Selecting the Set Flow Temperature Change via P Value
With the "P-BAND" setting, the change characteristics of the flow temperature are influenced
subject to the actual room temperature and the set maximum flow temperature.
Example:
Maximum flow temperature 80˚C (factory setting)
Set room temperature 20˚C
Stop hysteresis 0.4K (fixed)
"P-BAND" adjustable from 1.0 - 2.0 K
Factory setting 1.6K
A - P 1.0 K
B - P 2.0 K
C - P 1.6 K (factory setting)
Setting the I Component Time
With the "I-TERM" setting, the change characteristics of the flow temperature are recorded during a
set period.
"I TERM" adjustable from 2 - 15 minutes.
Factory setting 10 minutes
• If the actual room temperature is < the set room temperature and the actual room temperature
has not increased during the I-time, the set flow temperature is increased by 1 K.
• If the actual room temperature is > the set room temperature and the actual room temperature
has not decreased during the I-time, the set flow temperature is reduced by 1K.
