DHW PRIORITY TIMEOUT

(PARAMETER 43)

The length of time that a domestic call has priority over
a heating call can be set with Parameter 43.  

DHW Priority Timeout
(Parameter 43)

The boiler provides a domestic hot water priority feature,
which will block a heating call when a domestic hot water

call is present.  A DHW priority timeout setting of 

00

(Factory Setting) will not limit the length of a domestic
call.  A domestic call will always have priority over a
heating call.

A DHW priority timeout setting above 

00

will limit the

length of a domestic call when both domestic and heat-
ing calls are present.  Once the DHW priority timeout
setting has been reached, priority will shift to the heating
call.  If both calls continue, the priority will switch back to
the domestic call after reaching the DHW priority timeout
setting.  

A short DHW priority setting could lead to excessive
switching between domestic and heating calls.  This
excessive switching could adversely affect the pro-
duction of heat and domestic hot water.  

Parameter 43 Adjustment

To change Parameter 43, 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 43.

Press the “+” or “–“ button to change the setting of
Parameter 43 to the desired setting.  Press the STORE
button and confirm that the display blinks to indicate the
setting has been stored.
