DHW CALL BLOCKING TIME
(PARAMETER 41)
After the completion of a domestic call, a time delay peri-
od before responding to the next DHW call can be set
with Parameter 41.
DHW Call Blocking Time
(Parameter 41)
During the DHW call blocking time, the burner will not
respond to a domestic call. The DHW circulator will con-
tinue to operate for a domestic call. This blocking time
has no affect on heating calls. This DHW call blocking
feature prevents short cycling of the burner and extends
the life of the burner components.
A long DHW call blocking time could adversely
affect the production of domestic hot water.
Parameter 41 Adjustment
To change Parameter 41, requires entering the Access
Code as outlined on page 2. After entering the Access
Code, press the MODE button until the display shows
PARA
. Press the STEP button to reach Parameter 41.
Press the “+” or “–“ button to change the setting of
Parameter 41 to the desired setting. Press the STORE
button and confirm that the display blinks to indicate the
setting has been stored.
The parameter setting is multiplied by 10.2 seconds
to reach the actual DHW call blocking time. For
example, a setting of 3 results in a DHW call block-
ing time of 30.6 seconds.

DHW TO CH CALL BLOCKING TIME
(PARAMETER 42)
After the completion of a domestic call, a time delay
period before responding to a heating call can be set
with Parameter 42.
DHW to CH Call Blocking Time
(Parameter 42)
During the DHW to CH call blocking time, the burner will
not respond to a heating call. The CH circulator will con-
tinue to operate for a heating call. This blocking time has
no affect on domestic calls. This blocking time in con-
junction with the DHW post circulator feature may prevent
overheating of a low temperature heating system.
If the DHW to CH call blocking time is set to
00
(Factory Setting) and the boiler is receiving both domes-
tic and heating calls. At the completion of the domestic
call, the burner will continue to fire to maintain the CH
setpoint and the CH circulator will operate.
A long DHW to CH call blocking time could adverse-
ly affect the production of heat and the comfort
level of the occupants.
Parameter 42 Adjustment
To change Parameter 42, requires entering the Access
Code as outlined on page 2. After entering the Access
Code, press the MODE button until the display shows
PARA
. Press the STEP button to reach Parameter 42.
Press the “+” or “–“ button to change the setting of
Parameter 42 to the desired setting. Press the STORE
button and confirm that the display blinks to indicate the
setting has been stored.
The parameter setting is multiplied by 10.2 seconds
to reach the actual DHW to CH call blocking time.
For example, a setting of 3 results in a DHW to CH
call blocking time of 30.6 seconds.
