Digital Temperature Controller

A digital temperature controller is only available as an option
for standard watt units equipped with a drain. Use the following
procedures to operate a heated well equipped with the optional
digital temperature controller.
Startup
1. Move the ON/OFF (I/O) switch to the ON (I) position. The
indicator light on the switch glows when the unit is on.
• The digital temperature controller will energize and the
current temperature of the well or "LO" will appear on
the TEMPERATURE display. "LO" indicates the well
temperature is below 70°F (21°C).
CAUTION
BURN HAZARD: Some exterior surfaces on unit will get
hot. Use caution when touching these areas.
2. Press the key three times to verify the setpoint
temperature. ("SP" will be displayed after the second
press.)
• The setpoint temperature will be shown for 10 seconds.
After 10 seconds, the TEMPERATURE display will revert to
the current temperature of the unit. To change the setpoint
temperature, refer to "Changing the Setpoint Temperature"
in this section.
NOTE: The digital temperature controller is factory pre-set to
a setpoint temperature of 190°F (88°C) at the factory.
Once the setpoint temperature is changed, the new
setpoint temperature will remain in memory until it is
changed again.
3. Allow unit to preheat for approximately 30 minutes.
Shutdown
