Description
When outside temperature drops to this
8
number, the boiler circulator will run con-
stantly.
Use this parameter to modify the outside
9
temperature reading if needed to correct
for outside sensor location. Use only if sen-
sor is providing a false reading.
When the target outlet water temperature
0
is less than this setting, the boiler shuts
off.
• If a call for heat causes the boiler to re-
main at high fire for a time equal to Param-
1
eter 11, the control module increases out-
let water temperature setpoint by 18°F. For
each additional Parameter 11 time the heat
call continues, the set point is increased
another 18°F (never exceeding Parameter
4 + Parameter 23 (hysteresis off))
• To deactivate booster operation, set this
parameter to 0.
• The value of Parameter 12 reduces the
calculated setpoint temperature by the
amount set when the call for heat is from
2
outdoor temperature.
• We recommend not changing this param-
eter from the factory default of 0 (no paral-
lel shift).
• Use this parameter to change the maxi-
mum boiler input for central heating (CH).
Never above default value .
• When in central heating mode, the boiler
fan speed will not exceed this setting. In-
3
creasing fan speed increases boiler input;
decreasing fan speed decreases boiler in-
put.
• Never set below low fire setting or above
maximum value shown at left.
• Use this parameter to change the maxi-
mum boiler input for domestic water heat-
ing (DHW)-NEVER above default value.
5
• Boiler fan speed will not exceed this set-
ting in DHW mode. Increasing fan speed in-
creases boiler input; decreasing fan speed
increases fan speed decreases input.
•NEVER set below low fire setting or above
the maximum value shown at left.
