tank temperature • - non adjustable - control system sensed
temperature from the Temperature Probe.
tank probe offset
• - adjustable user setting, range -5° to +5°
(factory setting 0°).
The Tank Probe Offset is used to calibrate control system
temperature sensing. This can improve the precision of
temperature control in the storage tank and at points of use.
This feature can also be used to compensate for building
recirculation loops (hot water returning to the storage tank) that
may cause the heating cycles to terminate prematurely.
Example: If the current sensed temperature from the temperature
probe is 120°F (49°C) and the Offset setting for the probe is
adjusted to a value other than 0°, the control system would
calibrate or “offset” the sensed temperature from the probe.
Heating cycles would be activated and deactivated based on
the calibrated (offset) temperature.
note: The Tank Probe Offset should only be used if the hot water
supply temperature varies greatly from the Operating Set Point
setting. These settings are adjusted in the same way described
for the Operating Set Point and Differential Adjustment.
Operating Set Point 140°F
Differential 8°F
Tank Temperature 120°F
Tank Probe Offset 0°F

Select Heater Status from the Main Menu and press the Operational
Button under "SELECT" to enter this menu. This menu contains non
adjustable operational information. Use the Up & Down Buttons to
navigate the menu.
status • - displays the current Operating State, see Table 4 for a
description of the various operational states.
eco contact
• , blocked Inlet ps, blocked outlet ps, blower
prover ps - displays the current state of the switch contacts;
open or closed.
blower low on
• , blower high on - displays whether the
blower is running at high speed during Pre/Post purge and
the Heating operational states or the blower is running at low
speed during the Igniter Warm Up operational state; yes =
blower is running at the designated speed, no = blower is not
running at the designated speed.
Igniter on
• , Gas valve on - displays whether or not the control
system is currently energizing these water heater components;
yes = energized, no = de-energized.
Igniter current
• - displays whether or not the control system
has detected the required minimum current.
flame detected
• - displays whether or not the control system
has detected Main Burner flame during ignition from the Flame
Sensor.
E
• xternal Input enable - displays whether or not the S1
dipswitches have been configured to activate the Enable/
Disable circuit; yes = the Enable/Disable circuit has been
activated, no = the Enable/Disable circuit has not been
activated. The factory setting is "no" or deactivated.
Ignition trials
• - displays whether or not the S1 dipswitches
have been configured to allow 1 or 3 trials for ignition before
declaring an "Ignition Failure" Fault condition. The factory
setting is for 3 trials.
