select the desired setting and then press the enter pushbutton twice to
accept the change. This setting will alter the displayed value of the Steam
Pressure LOLIM programmable parameter, and how the steam pressure is
displayed when the controller is in normal operation.
P RANGE = 0-25 PSI (0–172 KPa) OR 0-145 PSI (0–1000 KPa)
–
The controller will indicate whatever value is currently selected (default
value = 0- 25 PSI). Using the pushbuttons, select the desired setting and
then press the enter pushbutton twice to accept the change. Changing
this setting will erase any changes that may have been made to the Steam
Pressure LOLIM, and will reset the Steam Pressure LOLIM to the default
values for that range.
S/W SWITCH = NORMAL or REVERSE
– This parameter allows
the direction of operation of S/W SW (summer/winter switch) to
be reversed. In NORMAL mode, a contact closure of the S/W SW
terminals would put the unit in to Summer Mode. In Summer
Mode the Steam Pressure is ignored and the controller only
responds to Domestic Water Temperature changes. In the
REVERSE mode a contact opening would have the same effect.
ET DISPLAY = ON/OFF?
-- This parameter controls whether or not the
Economizer Time accumulator is displayed. Using the pushbuttons, select
the desired setting and then press the enter pushbutton twice to accept
the change. Note – the accumulator is active even if not displayed.
R T D I S P L AY = O N / O F F ?
- - This parameter controls whether or not
the Burner Run-Time accumulator is displayed. Using the pushbuttons,
select the desired setting and then press the enter pushbutton twice to
accept the change. Note – the accumulator is active even if not displayed.
S T E AM L O L I M = x x x P S I o r K P a
- - This parameter is used by
the controller to set the low limit below which the controller will no longer
attempt to achieve any savings and will return control to the operating-
control. The indicated value will be what is currently set in the controller.
The default values are 2 PSI (14 KPa) for the low pressure unit, and 22
PSI (155 KPa) for the high pressure unit. The +/Menu and -/Menu
pushbuttons will allow the setting to be changed between the minimum 1
PSI (7 KPa) to a maximum of 10 PSI (70 KPa) for a low pressure unit and
a minimum of 12 PSI (84 KPa) to a maximum of 32 PSI (224 KPa) for a
high pressure unit. If the steam pressure goes below this value while the
operating-control is calling for the burner to run, the controller will indicate
“HEATING/LOLIM” on the display.
D O M E S T I C
LOLIM = xxx ˚F(C)
- - This parameter is used by the
controller to set the low-limit temperature for the domestic hot water. When
the domestic water temperature goes below this setting, the controller will
no longer attempt to achieve any savings and will return control to the
operating-control. The indicated value will be what is currently set in the
contro
ller (default = 115˚F / 46˚C). The +/Menu and -/Menu pushbuttons
will allow the setting to be changed between the maximum (180
˚F/82˚C)
and minimum
(90˚F/32˚C) settings. If the ‘Domestic’ water temperature
goes below this value while the operating-control is calling for the burner to
run, , the controller will release the burner to run, and will indicate
“HEATING/LOLIM” on the display.
R E T U R N L O L I M = x x x
˚F(C)
- - This parameter is used by the
controller to set the low-limit temperature for the condensate return. When
the condensate temperature goes below this setting, the controller will no
longer attempt to achieve any savings and will return control to the
operating-control. The indicated value will be what is currently set in the
contro
ller (default = 90˚F / 32˚C). The +/Menu and -/Menu pushbuttons will
allow the setting to be changed between the maximum (180
˚F/82˚C) and
minimum (70
˚F/21˚C) settings. If the ‘Condensate’ temperature goes
below this value while in Winter Mode, and the operating-control is calling
for the burner to run, the controller will release the burner to run, and
indicate “HEATING/LOLIM” on the display.
R E T U R N D I F F =
xx ˚F(C)
- - This parameter is used by the
controller to set the point at which the burner will be allowed to run when in
Winter Mode. In Winter Mode, the burner will be inhibited from firing as
long as there is energy in the condensate. When the condensate
temperature goes below this setting, the controller will no longer attempt to
achieve any savings and will return control to the operating-control. The
indicated value will be what is currently set in the controller (default = 10
˚F
~ 6˚C). The +/Menu and -/Menu pushbuttons will allow the setting to be
changed between the maximum (25
˚F/18˚C) and minimum (5˚F/3˚C)
settings. If the ‘Condensate’ temperature goes below this value while in
Winter Mode, and the operating-control is calling for the burner to run, the
controller will release the burner to run, and indicate “HEATING” on the
display.
PREPURGE = xxx SEC
-- This parameter indicates the pre-purge time
currently programmed into the controller (default value = 000 seconds).
The +/Menu and -/Menu pushbuttons will allow the setting to be changed
between the maximum (240 Secs.) and minimum (000 Secs.) settings.
This setting is important for proper run-time hours accumulation.
MAX ECON = xxx MIN
-- This feature of the controller is to limit the
maximum amount of time that the controller is allowed to remain in the
Economizer Mode. The indicated value will be what is currently set in the
controller (default = 30 minutes). The +/Menu and -/Menu pushbuttons will
allow the setting to be changed between “Disabled” or the maximum (120
Mins.) and minimum (5 Mins.) settings. If the controller goes in to the
“HEATING MODE” as a result of this feature, there will be a period (“.”)
appended to the word “MODE” on the display.
MAX STBY = xxx MIN
-- This feature of the controller is to limit the
maximum amount of time that the controller is allowed to remain in the
Standby Mode as a means of monitoring the internal electronics against
failure. If a heating call is not sensed within the prescribed time period, the
timer will expire and the control will take itself out of the circuit (fail-safe).
A period (“.”) will be appended to the “
STANDBY MODE.
” message to
indicate that this timer has expired for service personnel. It will only reset
upon sensing a call from the aquastat. Cycling power to the control will
NOT reset the timer.
The indicated value will be what is currently set in the controller (default =
180 mins). The +/Menu and -/Menu pushbuttons will allow the setting to be
changed between “Disabled” or the maximum (180 Mins.) and minimum
(45 Mins.) settings.
DISABLING THIS FUNCTION IS NOT RECOMMENDED!
This condition is not necessarily a fault and will occur naturally if the
heating system has been “off” or there are long periods of time between
aquastat heating calls. The only time that this should be considered a
problem is if the controller is in “STANDBY MODE.” and the burner is
running. This would indicate a failure of the on-board electronics and that
the IntelliCon has taken itself out of the circuit.
FOLLOW THE SCREEN INSTRUCTIONS TO EXIT THE
CONFIGURATION MODE AND REBOOT THE CONTROL.
