TEMPERATURES MENU
Operating Set Point
User adjustable setting 90°F to 190°F range; factory default is 120°F. When the water temperature sensed by the control system from the immersion Temperature Probe reaches the Operating Set Point the control system will end the heating cycle. A call for heat will be activated again when the water temperature drops below the Operating Set Point minus the 1st Differential Setting.
Example: Operating Set Point is 120°F, the 1st Differential Setting is 2°F (factory default). A call for heat will be activated when the sensed water temperature drops to 118°F.
Differential Settings
Adjustable user setting(s) 1°F to 20° range; factory default is 2°F. The water heaters covered in this manual will have between 1 and 5 heating elements. There is at least one Differential Setting on all models. There will be additional Differential Settings for each additional heating element installed.
Operating Sequence
On a water heater equipped with 3 heating elements, with an Operating Set Point of 120°F and all Differential settings at 2°F the On/Off sequencing of heating elements would be as follows:
ELEMENT | DIFFERENTIAL | TURN ON TEMP | TURN OFF TEMP | |
NUMBER | SETTING | |||
|
| |||
|
|
|
| |
Element 1 | 2°F | 118°F | 120°F | |
|
|
|
| |
Element 2 | 2°F | 116°F | 118°F | |

|
| |
Element 3 | 2°F | 114°F | 116°F | |

TABLE 4.
Tank Temperature
Non adjustable information display. Current water temperature as sensed by the control system from immersion Temperature Probe.
Tank Probe Offset
User adjustable setting
Used to calibrate for slight differences in control system temperature sensing. This can improve the precision of temperature control in storage tank and at points of use. This feature can also be used to compensate for building recirculation loops (hot water returning to storage tank) that may cause the heating cycle to terminate prematurely.
