ECL Comfort 210 / 310, application A214 / A314
5.9 Fan / acc. control (fan / accessory control)
This section describes the function possibilities for relay 1 (F1),
relay 2 (P2), relay 3 (X3), relay 4 (X4), relay 5 (X5), relay 7 (P7) and
relay 8 (P8).
Schedule 1 is set in circuit 1, whereas Schedule 2 (and 3) are set in
circuit 2 or "Common controller".
When the ECL Comfort controller is in Saving mode, the system can
be totally stopped or work in Saving conditions.
The output X3 ('Optional function', ID 1x090) is flexible and has
different options, depending on application. See the table at the
parameter description.
A214.6 and A314.3:
The parameter "Fan function" (ID 11137) has no functionality. The
parameter is prepared for future use.
A314.4 … A314.7 and A314.9:
The output X4 is controlled from Schedule 3.
Comfort = relay closed; Saving = relay open.
The output X5 is used in A314.6 and A314.7. X5 is ON at cooling
demand.
The output P7 (in ECA 32) is used in A314.4 . . . A314.7 for control of
the circulation pump in the Fluid battery.
The output P8 (in ECA 32) is used in A314.4, A314.5 and A314.9 for
control of the "Night damper".
The parameter 'Stop difference' (ID 1x194) is used differently,
depending on application:
•
A214.6: When X3 is set to act as room thermostat.
•
A314.4 … A314.7:
When utilizing the "Night cooling" function. The room
temperature must be "Stop difference" higher than the outdoor
temperature for enabling "Night cooling".
Parameters indicated with an ID no. like "1x607" mean a universal
parameter.
x stands for circuit / parameter group.
