Operation Instructions
Control panel buttons
On/Off Button
Press the On/Off button to power on the electronic
control. Press and hold the on/off button for 2 seconds
to turn the electronic control off . The status indicator
LED will illuminate in the power ON state.
NOTE:
The IRR
or INJ must be selected to turn on the heating circuit.
Up Arrow / Down Arrow Buttons
Used to increase or decrease the temperature set-point
as desired. Continuous pressure to a button increases
the increments in which the values will change.
Overtemp Alarm Button
Used to display the current over-temperature trip-
point. The alarm trip-point is always 6°C (10°F) above
the temperature setting. When the green overtemp
indicator is blinking, the warmer has entered an over-
temperature condition.
IRR Button
Used to select the Irrigation Fluids mode and to display
the IRR set-point temperature. The temperature range is
37°C to 66°C (98°F to 150°F). The green IRR indicator and
the yellow indicator below the IRR button illuminates
when the IRR set-point temperature is being displayed.
INJ button
Used to select the Injection Fluids mode and to display
the INJ set-point temperature. The temperature range is
37°C to 40°C (98°F to 104°F). The green INJ indicator and
the yellow indicator below the INJ button illuminates
when the INJ set-point temperature is being displayed.
NOTE:
When the electronic control is powered on, IRR or INJ
must be selected to turn on the heating circuit. To switch
between the irrigation and the injection mode, turn
the electronic control off and then back on. Be careful
to cool the cavity down prior to switching from a high
temperature to a lower temperature or the electronic
control will display an unwanted overtemp alarm.
LED display status indicators
Overtemp
When the electronic control senses a temperature
6°C (10°F) greater than the set point, this indicator
illuminates, the audible alarm sounds and the on/
off button indicator blinks. The green indicator of the
overtemp button will stop blinking once the warmer
temperature drops back to the set point temperature
range. To silence the alarm and extinguish the error
indicator aft er the temperature has dropped into the
selected temperature range, use the on/off button to
reset the electronic control. Inspection of the product in
the cavity may be necessary.
Error
This illuminates when an over-temperature condition
is detected. The error indicator will remain illuminated,
even aft er the over-temperature condition is cleared,
until the warmer is turned off . This will alert the
operator that the electronic control has indicated
an overtemp and the product in the cavity should
be inspected.
Lock
This illuminates when the lock feature is engaged.
Power Fail Detection
If the power were to fail for any reason while electronic
control is powered on, the warmer will retain in
memory its current operating state. When the power
is restored, the electronic control will alarm once and
resume operating in its previously set mode, but will
alert the operator that such an event has occurred. The
on/off status indicator will blink.
Press the on/off button once to acknowledge that the
power has been restored. The on/off status indicator
will stop blinking. When pressing the on/off button, the
display will indicate the time period of the outage in
hours and minutes (hh:mm), then return to the normal
display and previously set mode. Inspection of the
product in the cavity may be necessary.
