Dettson Chinook C15-M-V Instructions D'installation Et Manuel Du Propriétaire page 18

V/W2 – This terminal is used to connect the modulating
signal (V) from a non-communicating, fully modulating
thermostat specified for use with this furnace. It is used
to transmit the firing rate (determined by the thermostat)
to the furnace control.
NOTE: Do not apply 24 VAC to the V/W2 terminal (as
with a jumper to R for diagnostic purposes) with a
non-communicating, modulating thermostat.
B - This terminal is used to pass a reversing valve
signal to a condenser. It is only a holding place for
connecting a wire from the thermostat and a wire from the
condenser. It does not change the airflow of the cool/heat
commands.

6.4 ALTERNATE POWER SUPPLY
Dettson doesn't recommend to operate the furnace on a
generator or other alternate power supply. If so it must
produce a smooth sinusoidal waveform for compatibility
with the furnace electronics. The alternate power supply
must generate the same voltage, phase, and frequency
(Hz) as shown on the furnace rating plate.
Power from an alternate power supply that is non-
sinusoidal may damage the furnace electronics or cause
erratic operation.
Contact the alternate power supply manufacturer for
specifications and details.
