CH BURNER / CIRCULATOR FUNCTION
SETUP
The type of CH burner and CH circulator operation can
be revised to meet specific application requirements.
The Prestige offers 4 different CH operation setup
modes. Those operational setups are defined as:
-
OFF
In this mode the Prestige will NOT recog-
nize any request for a “call for heat” for space
heating. This mode shuts down the CH opera-
tion, both burner and CH circulator function, of
the Prestige control. The Prestige will maintain
all DHW operation, both burner and DHW circu-
lator function, as well as the freeze protection of
the boiler.
-
ON
In this mode, factory setting, the Prestige
operates the CH burner and circulator when a
request for a “call for heat” occurs. This request
can be from the end switch of either a room ther-
mostat or a zone panel relay.
-
OFF + Pump Continuous
In this mode of
operation the Prestige will block the burner oper-
ation during a request for “call for heat” from the
CH system. The CH circulator will become
blocked during a DHW request for heat. The
Prestige will maintain all DHW operation, both
burner and DHW circulator function, with
domestic priority feature. When in the
Heat
Request - Outdoor Sensor
application mode
the summer / winter switch or block temperature
(Parameter 10) won’t shut down the CH circula-
tor function.
-
ON + Pump Continuous
The Prestige will
maintain continuous circulation by energizing
the CH circulator and only the burner function
will be determined on a request for heat from the
system. The DHW function will remain, as well
as domestic priority.
Parameter Adjustments - OFF Mode
The parameter adjustment to set the CH operational
option to
OFF
can be done either through the STBY
mode during normal operation or by entering into the
CODE mode.
When the unit is in normal operation and in the STBY
mode, press MODE once to enter PARA. Press STEP
three times to Parameter 3. Press - or + button to adjust
to the following revised setting and press STORE to save
the setting.
The unit can also be place into the
OFF
mode when the
unit is in normal operation without entering the PARA
mode. In the STBY mode press and hold for approxi-
mately 2 seconds the + button. The panel display
should flash a c followed by a display of
ccccOOOOFFFFFFFF
.
This operational function only controls the burn-
er operation. If the current parameter setting is
set for continuous pump operation, that circula-
tor function will remain when the + button is
press. To alter both CH burner and circulator
function the parameter setting must be revised
in the PARA mode.
The parameter adjustment of Parameter 2 in the CODE
mode is done by following the steps given in Program
Access Section on page 2 until the display shows
3_
XX.
Use the + or - to adjust to the revised setting list-
ed below and press STORE to save the setting.
Parameter Adjustments - ON Mode
The Prestige is factory set to this mode. However, the
parameter adjustment to set the CH operational option
to
ON
can be done either through the STBY mode dur-
ing normal operation or by entering into the CODE
mode.
When the unit is in normal operation and in the STBY
mode, press MODE button once to enter PARA. Press
STEP button three times to Parameter 3. Press - or + but-
ton to adjust to the revised setting listed below and press
STORE to save the setting.
