Страница: 15 / 21

TEMPERATURE ADJUSTMENT:
1. Tum "OFF" the electrical power to the water heater. If the power disconnect point is out of sight, lock
it in the open ("OFF") position and tag to prevent unexpected application of power
2. Open the water heater's electrical access panel
3. Adjust each immersion thermostat to the desired temperature setting by turning the adjusting knob.
Each thermostat will be factory pre-set to approximately 125° F (51.7° C) or less as shipped
4. Close the water heater's electrical access panel.
5. Turn "ON" the electrical power to the water heater
CAUTION:
The maximum temperature set-point that should be set for the Immersion Thermostats or
programmed into the Electronic Temperature Step Control Module is 180° F (82° C).
ELECTRONIC TEMPERATURE STEP MODULE:
The water heater uses an optional adjustable electronic temperature
control to provide staged ON/OFF control of the electric heating
elements. Operation is based on temperature input from an immersion
temperature sensor. The sensor is a positive coefficient platinum
thermistor. The sensor is placed in a well located above the heating
elements it is controlling. A liquid crystal display is provided to indicate
sensed temperature and operating parameters. The temperature control
may operate in as many as four stages of control. For more stages of
operation, multiple electronic temperature control sequencers are installed
and wired to operate in series.
