BOILER SETPOINT FOR DHW CALL
(PARAMETER 1 & 21)
The boiler setpoint for a domestic call is calculated by
adding Parameters 1 & 21. The maximum boiler set-
point is 194°F. The factory settings result in a boiler set-
point of 186°F (140°F + 46°F) for a domestic call.
DHW Setting
(Parameter 1)
Setpoint Value Addition for DHW
(Parameter 21)
If Parameter 1 is set below 134°F, it is recommended
that Parameter 21 be increased to maintain a high boil-
er setpoint during a domestic call. A low boiler setpoint
will adversely affect the Indirect Water Heater perform-
ance and can lead to longer domestic calls.
Parameter 1 Adjustment
To change Parameter 1, press the MODE button until the
display shows
PARA
. Press the STEP button once to
reach Parameter 1. Press the “+” or “–“ button to change
the setting of Parameter 1 to the desired setting. Press
the STORE button and confirm that the display blinks to
indicate the setting has been stored.
Parameter 21 Adjustment
To change Parameter 21, 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 21.
Press the “+” or “–“ button to change the setting of
Parameter 21 to the desired setting. Press the STORE
button and confirm that the display blinks to indicate the
setting has been stored.
When selecting continuous DHW circulator opera-
tion, the installer should install a thermostatic mixing
valve on the outlet of the Indirect Water Heater to pre-
vent a potential scalding hazard. Failure to comply
could result in a scalding hazard causing severe per-
sonal injury, death, or substantial property damage.
When selecting continuous DHW circulator opera-
tion, the DHW circulator will have priority over the
CH circulator which will prevent the CH circulator
from operating during a heating call.
Parameter 2 Adjustment
To change Parameter 2, press the MODE button until the
display shows
PARA
. Press the STEP button twice to
reach Parameter 2. Press the “+” or “–“ button to change
the setting of Parameter 2 to the desired setting. Press
the STORE button and confirm that the display blinks to
indicate the setting has been stored.
A shortcut can also change Parameter 2 and disable a
domestic call. Press and hold the “–“ key for approxi-
mately 2 seconds while in STBY mode. Releasing the
“–“ key when
dOFF
is shown on the display will disable
the DHW function of the boiler. To enable the DHW func-
tion, press and hold the “–“ key while in STBY mode and
release when the display shows
2_
XXX
where
XXX
represents the DHW setpoint.
This method of using the “–“ button to disable a
domestic call will not disable the DHW circulator if it
has already been placed in continuous operation.
To change both burner and circulator operation,
Parameter 2 must be changed in the PARA mode.
