Section 8, Operating the Heating Module
8-6 The POLAR™HD Heating Module
Activating the Burner and AC immersion Element(s)
Jointly
• Turn the burner switch ON and place the AC power switch on
the Remote Operating Panel to either the one element or two
element position. The Burner and AC Heat (green) LED’s will
turn ON indicating the diesel burner and AC element(s) have
been selected.
8.6 Activating the Cabin Fan Heaters
through the Thermostats
(Distribution Module Equipped Systems Only) (Burner or
AC Heat or Engine Heat Source Available)
• Any thermostat connected to the Distribution Module’s Zone
Control Board and calling for heat will cause the cabin fan
controlled by that thermostat to be enabled. The ITR cabin
fan has a built-in aquastat that prevents the cabin fan from
blowing cold air. Once the room temperature has reached the
temperature called for by the thermostat the cabin fan will
turn off.
8.7 Activating the Domestic Hot Water
(POLAR™HD Heating Module and Distribution Module used
in Tandem) (Burner or AC Heat On)
• As long as heat is available in the POLAR™HD Heating
Module, the Distribution Module (Optional) will respond to a
call for domestic hot water. Ensure that a heat source has
been selected (i.e. Burner, AC, Engine). The production of
the domestic hot water is continuous on the Burner
operation and limited when using AC or Engine.
The domestic water pump is not a part of, nor controlled by the
Distribution Module or The POLAR™HD Heating Module.
8.8 Activating Engine Heat & Pre-heat
(POLAR™HD Heating Module and Distribution Module used
in Tandem) (Burner or AC Heat On)
