Temperatures Menu
Description/Action
•
Differential - Adjustable user setting that changes the tank temperature
differential with a range of 2° to 20°F. The factory setting is 8°F.
•
Tank Temperature - Non adjustable. Control system sensed
temperature.
•
Tank Probe Offset - adjustable user setting, range -5° to +5° (factory
setting 0°).
•
NOTE: These settings should only be used if hot water supply
temperature varies greatly from the Operating Set Point setting.
•
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 temperature from the temperature probe is
120°F (49°C) and the Offset setting 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. A -5° setting results in
+5° hotter water.
•
These settings are adjusted as described in Operating Set Point and
Differential Adjustment on page 44.
Heater Status Menu
Description/Action
Press Heater Status from the Main Menu to enter this menu. This menu contains
non adjustable operational information. Use the slidebar to navigate the menu.
•
Status - displays the current Operating State, see Table 19 on page 43.
•
ECO Contact, Blocked Inlet PS, Blocked Outlet PS - displays the
current state of the switch contacts; open or closed.
•
Igniter On, Gas Valve On - displays whether or not the control system is
currently energizing these water heater components; yes = energized,
no = de-energized.
•
Flame Detected - displays whether or not the control system has
detected Main Burner flame during ignition from the flame sensor.
•
Anode Current, Anode Tank Voltage, Anode Drive Voltage - displays
the powered anodes current and voltage levels.
NOTE: Anode Current, Anode Tank Voltage, & Anode Drive Voltage will
only be displayed if the water heater is equipped with powered (non-
sacrificial) anodes.
NOTE: Menu displays shown are for informational purposes only. The
actual heater display will vary dependent upon the operational state of the
water heater.
