8.5 Activating the Burner (Primary) and
AC Heat (Secondary) from the Remote
Operating Panel
Activating the Burner (Primary Heat Source)
• The burner switch on the Remote Operating Panel controls the
ON/OFF of the diesel burner (primary heat source). When the
burner switch is turned ON, the diesel portion of the
POLAR™HD Heating Module will turn ON after ten seconds.
The Burner LED will turn ON when the diesel burner has been
activated. The burner will continue to operate until the coolant
in the POLAR™HD Heating Module reaches the set operating
temperature range. At this point, the diesel burner will turn
OFF. If the POLAR™HD Heating Module coolant should cool
down below this temperature range, the burner will again
commence firing and will continue until either the burner
switch on the remote panel is turned OFF or the temperature
range is again achieved. If the burner switch on the remote
panel is turned OFF, the burner stops and the POLAR™HD
Heating Module enters a two minute cool down stage prior to
completely shutting down.
Activating the AC Immersion Element(s) (Secondary Heat
Source)
• Place the AC power switch on the Remote Operating Panel to
either the one element or two element position. The AC Heat
(green) LED will turn ON indicating the AC element(s) are
energized and the coolant is being electrically heated. They
will continue to operate until the coolant in the POLAR™HD
Heating Module reaches the set operating temperature range.
At this point, the elements will turn OFF. If the POLAR™HD
Heating Module coolant should cool down below this
temperature range, the AC elements will again be energized
and will continue until either the AC switch on the remote
panel is placed in the OFF position or the temperature range
is again achieved. If the AC element switch on the remote
panel is turned OFF, the AC elements are de-energized and
the AC Heat (green) LED turns OFF.
