This is a Yes/No type of parameter
WARNING:
This parameter will clear ALL of the time and counter accumulators.
Plug into the top jack to perform the desired function, or plug into the lower jack to
answer NO (and proceed to the next parameter, or allow the 7 second delay to
expire and proceed to the next parameter).
For all of the parameters that follow, after making a change and the “**DATA
SAVED**” message is displayed, you will be given an additional chance to
change that parameter again, before advancing to the next programmable
parameter.
This is an Increase/Decrease type of parameter
This parameter indicates the pre-purge time currently programmed into the
controller (default value = 000 seconds). To change this setting, plug in the sensor
to the appropriate jack to increase or decrease the value.
OR
This is a Yes/No type of parameter
The controller will prompt you to change to whatever value is NOT currently
selected (default value = F). For example, if the parameter is currently set for
degrees F, the only choice will be to change to degrees C. This setting will alter the
indicated values of the next two (2) programmable parameters, and how the
indicated temperatures are displayed when the controller is in operation. Plug into
the top jack to change the parameter, or plug into the lower jack to answer NO (and
proceed to the next parameter, or do nothing and allow the 7 second delay to
expire and proceed to the next parameter).
OR
This is an Increase/Decrease type of parameter
This parameter is used by the controller to set the low-limit temperature for the
heating water. When the heating water temperature goes below this setting,
“HEATING/LOLIM” will be displayed, and the controller will no longer attempt to
achieve any savings and will return control to the operating-control. To change this
setting, plug the sensor into the appropriate jack to increase or decrease the value.
The indicated value will be what is currently set in the controller (default = Auto).
When in “AUTO” and only the heating water sensor is used, the default value of
120
˚F / 49˚C will be used. When in “Auto” and both sensors are used the default
value of 145
˚F / 62˚C will be used. To change this setting, plug the sensor into the
appropriate jack to increase or decrease the value. The range of adjustment is
between
90˚F/32˚C and 180˚F/82˚C. Remove the sensor when the desired value is
reached.
OR
This is an Increase/Decrease type of parameter
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,
“HEATING/LOLIM” will be displayed, and the controller will no longer attempt to
achieve any savings and return control to the operating-control. To change this
setting, plug the sensor into the appropriate jack to increase or decrease the value.
The indicated value will be what is currently set in the controller (default = 120
˚F /
49
˚C). The range of adjustment is between 90˚F/32˚C and 180˚F/82˚C. Remove
the sensor when the desired value is reached.
OR
This is a Yes/No type of parameter
This parameter controls whether or not the Economizer Time accumulator is
displayed. The controller will prompt you to change to whatever value is NOT
currently selected (default value = ON). For example, if the parameter is currently
set for “ON”, the only choice will be to change to “OFF”. Note – the accumulator is
active even if not displayed. Plug into the top jack to change the parameter, or plug
into the lower jack to answer NO (and proceed to the next parameter, or do nothing
and allow the 7 second delay to expire and proceed to the next parameter).
OR
This is a Yes/No type of parameter
This parameter controls whether or not the Burner Run-Time accumulator is
displayed. The controller will prompt you to change to whatever value is NOT
currently selected (default value = ON). For example, if the parameter is currently
set for “ON”, the only choice will be to change to “OFF”. Note – the accumulator is
active even if not displayed. Plug into the top jack to change the parameter, or plug
into the lower jack to answer NO (and proceed to the next parameter, or do nothing
and allow the 7 second delay to expire and proceed to the next parameter).
OR
This is a Yes/No type of parameter
This parameter controls whether or not the Average Savings accumulator is
displayed. The controller will prompt you to change to whatever value is NOT
currently selected (default value = ON). For example, if the parameter is currently set
for “ON”, the only choice will be to change to “OFF”. Note – the accumulator is active
even if not displayed. Plug into the top jack to change the parameter, or plug into the
lower jack to answer NO (and proceed to the next parameter, or do nothing and allow
the 7 second delay to expire and proceed to the next parameter).
OR
This is an Increase/Decrease type of parameter
This parameter limits the maximum amount of time that the controller is allowed to
remain in the Economizer Mode. To change this setting, plug the sensor into the
appropriate jack to increase or decrease the value. The indicated value will be what
is currently set in the controller (default = DISABLED). The range of this adjustment is
between 10 and 120 minutes and
“DISABLED. Remove the sensor when the desired
value is reached. If the controller goes in to the heating mode as a result of this
feature, the
message “HEATING/MAX ECON” will be displayed.
OR
This is an Increase/Decrease type of parameter
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.
To change this setting, plug in the sensor when prompted. The indicated value will be
what is currently set in the controller (default = 180 minutes). The range of this
adjustment is between 45 and 180 minutes and
“DISABLED. Remove the sensor
when the desired value is reached.
Disabling this function is NOT recommended!
This condition is not necessarily a fault. It will occur naturally if the heating system has
been “off” or there are long periods of time between aqua-stat 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.
AFTER THE LAST PARAMETER IS REACHED THERE WILL BE A
BRIEF DELAY AND THE CONTROLLER WILL RESET. DURING THIS
TIME THE SENSOR(S) SHOULD BE RECONNECTED OR THE
CONTROLLER WILL ATTEMPT TO GO INTO THE CONFIGURATION
MODE AGAIN. IF YOU DON’T REACT QUICKLY ENOUGH, SIMPLY
TURN THE CONTROLLER OFF, CONNECT THE SENSOR(S) AND
TURN THE CONTROLLER BACK ON.
