Module 4 Temperature Recovery
This module calculates a continuous positioning signal (YT) from the basic
temperature controller (X1). If there are no limitations (that is, P4 is zero), the
module outputs a positioning signal (YT) from 0 to 100 percent.
If there is a limitation, the module converts it into a maximum limitation with mixed
air damper operation and into a minimum limitation with regenerative transfer
operation. Depending on the position of the characteristic curve from Module 3, the
positioning signal is direct-acting or reverse-acting. ECO uses the maximum limit for
the direct control of mixing, return, and fresh air dampers that operate with one
motor.
