ENG
The function can be configured using the screens accessible in branches Eea-- and Eeb--.
The options for calculating the demand percentage for the supplementary actions, are shown in the
following table:
Value Description
NONE No additional contribution to heat recovery
HR1+HR2 Contribution from both modules: HR1req+HR2req, limited to 100%
HR1 ONLY Contribution from HR1 only
HR2 ONLY Contribution from HR2 only
In order for heat recovery to be activated, certain conditions need be verified. The thresholds can be set on
screen Eeab02:
cod. +030220595 - 1.2 - 13.08.2020

CONFIGURATION

Screen Eeab01 is used to choose how many heat recovery
modules are to be activated, up to two, and how the demand
percentage should be calculated for the supplementary
actions.
The following are required for heat recovery activation:
•
the pressure in the gas cooler is above a threshold;
•
a minimum OFF time has elapsed since the previous
activation.
The user can choose whether to disable the floating
condensing function when heat recovery is active: if setting
YES on screen Eeab04, floating condensing will be disabled
when at least one heat recovery module is active.
The function can be enabled based on time bands, which
preliminarily enable the function; effective activation
depends on the calculated heat demand.
Similarly, the activation trigger can be independent from the
closing time bands. These settings are accessible on screen
Eeab05.
The scheduler inside the controller can be used to specify the
activation time bands.
If required, the heat recovery function can also be active in
the closing time bands.
