7.2.2 OPTIONS SELECTION
Before entering the OPTIONS setting the wall thermostat must be on OFF position. To add options to your
Alterna II furnace, you must first go to the sub-
menu ‘’SELECTION’’ in the ‘’OPTION’’ menu to activate the
different options desired. By default, no option is activated. To activate one or more options, you must press the
box next to the desired option. When an option is chosen, the square selected becomes green to confirm that
the system has taken your selection. If no option is to be added to your furnace, you can skip this section. An
example is shown below.
To confirm your options
selection, press the ‘’SAVE&EXIT’’ button. This step will take you to a list of questions
regarding your selections that are essential to the proper functioning of your options.
7.2.3 PRIORITIZING HEATING SOURCES
If you have configured one or more auxiliary heating sources (electric unit, heat pump), you must choose the
order of operation of your different heating sources when a heating demand from the wall thermostat is sent to
the furnace. If for example your pellet furnace is selected as first priority but runs empty on pellets, the auxiliary
heating source set as second priority will take over.
In the case where an outdoor temperature probe (or dual energy system) is used and a heat pump is set as the
first heating priority, the system will change to second priority if the temperature goes below the outdoor probe
pre-established set point
(fare change temperature or heat pump’s efficiency limit).
7.2.4 SETTING THE DISTRIBUTION FAN SPEEDS
It is possible to adjust the distribution fan speed for the circulation mode, the air conditioning mode and also for
the different auxiliary heating modes. During pellet heating, the fan speeds are programmed in order to provide
the best heat exchange and cannot be adjusted.
Adjustment of the fan speed allows the installer to balance the hot air plenum system in accordance with the
various operating options. The user can access the speed adjustment for ‘’CIRCULATION’’ mode at any time.
However, the other speeds are only accessible when the option in question is activated in the ‘’OPTIONS’’
