Description
Room Probe Temperature Modulation
If enabled (On):
It allows the Smartech to modulate the system
flow temperature according to the difference between the desired
room temperature and the detected one
If disabled (Off):
The system flow temperature will be kept
constant until the desired room temperature is reached
Note:
If the climatic offset function is enabled the maximum
system flow temperature will be calculated based on the external
ambient temperature according to the offset curve set. See
Section 7.5
Proportional Band
The temperature band for set point approach modulation
Time Interval
