•
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

•
Status - displays the current operating State, see Table 6
on page 48 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 Combustion Blower is running at high speed during
Pre/Post purge and the Heating operating states or the
Combustion Blower is running at low speed during the
Igniter Warm up operating 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 flame at the Burner during ignition
from the Flame Sensor.
•
External 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.
