Electric Heat Option
Electric Heat Components
Electric Heating Element
The unit is optionally equipped with a 1.5kw or 5kw
heat strip. The heat strip is located next to the blower
assembly and uses resistive heat.
Thermal Overload
The heater assembly has a thermal overload wired in
series with the heating element. This device has a
cycling limit which opens at 130°F and resets at 80°F.
The limit is also equipped with a redundant thermal
fuse that will open at 150°F.
Electric Heat Operation
The heat strip will be activated on a call for heat. This
call can be generated by the LV or the wall-mount unit
operating in orphan mode.

Bard Guard Anti-Theft System Option
The unit has the option to be shipped from the factory
with a low pressure switch, panel sensors and a speaker.
These devices are used with the Bard Guard BG1000 anti-
theft controller to provide an anti-theft measure. These
sensors and switch form a loop that when connected to
the BG1000 controller will cause the system to go into
alarm if any of the front panels or coil assemblies are
removed without being disarmed. The speaker provides an
audible alert that the system is being tampered with. The
Bard Guard anti-theft control sensor connection is wired
to terminals 7 and 8 on the wall-mount unit. The speaker
connection is wired to terminals 5 and 6 on the wall-
mount unit. See the latest revision of BG1000 Installation
Instructions 2100-672 for directions on connecting the
wall-mount units to the BG1000 controller.
Inverter Option
The inverter is only used in applications where a
generator is not present and the wall-mount units must
run during a power loss event. The inverter will always
keep power available to the wall-mount units during a
power outage. In the event of a power outage, a power
loss relay in the FUSION-TEC HR Series wall-mount
unit will be energized and will only allow the blower and
economizer to run while powering the controller. The
inverter converts either 24 VDC or 48 VDC, depending on
the model, to 230 VAC. A relay output from the inverter
will also communicate an alarm to the supervisory
controller in the event of an inverter failure. This variable
can be communicated through the Ethernet port for
integration into a building management system. The units
will continue to run in economizer-only operation until
power has been restored or the battery power has been
depleted.
When the FUSION-TEC HR Series wall-mount unit is
operating under inverter power, shelter economizer
cooling will only occur if outside temperatures fall below
indoor temperatures and blower speeds are slightly
reduced to conserve battery power.
