Description
• Use this parameter to increase the mini-
mum input of the boiler. increasing fan
7
speed increases boiler input; decreasing
fan speed decreases input.
• NEVER set outside values shown at left.
• Use this parameter to increase the mini-
9
mum input of the boiler during ignition.
• Increasing fan speed increases boiler in-
put; decreasing fan speed decreases input.
• SET ONLY at recommended (default) values.
Parameter 20 is the length of time the
0
boiler circulator continues to operate after
completing a central heating cycle.
Parameter 21 is the length of time the
1
boiler circulator continues to operate after
completing a dHW cycle.
• Differential may also be referred to as
"hysteresis"
2
•This is the temperature the boiler water
must drop below setpoint temperature to
turn the boiler on.
• Differential may also be referred to as
"hysteresis"
• This is the temperature the boiler water
3 must not must rise above setpoint temper-
ature to turn the boiler off.
• As outlet temperature increases, the con-
trol module reduces boiler input. if tem-
perature continues to rise with boiler with
minimum input, the boiler will shut down
when the temperature reaches setpoint
temperature plus Parameter 23.
• Differential may also be referred to as
"hysteresis"
• This is the temperature boiler water must
4
drop below setpoint temperature to turn
the boiler on. Boiler outlet water setpoint
temperature is 180°F during dHW mode.)
• Differential may also be referred to as
"hysteresis"
• This is the temperature boiler water must
5
rise above setpoint temperature to turn
the boiler off. (as outlet temp. increases,
the control module reduces boiler input. if
temperature continues to rise with boiler
at minimum input, the boiler will shut down
when the temperature reaches setpoint
temperature plus Parameter 23.)
