operation
HeATInG DeMAnD
one-STAGe THerMoSTAT
W1-
The thermostat closes the R-W1 circuit, which activates 100%
of the heating sequence. The blower starts up at medium speed and
the furnace elements are activated one by one to reach the adjustable
temperature limit set on the potentiometer of the furnace control card.
If there is still a W1 heating demand after 30 minutes, the heating
sequence continues as per the W2 sequence.
or W2-
If there is still a W1 heating demand after 30 minutes, the
sequence continues as follows: the blower switches to the medium
speed and all the furnace elements are activated one by one (100%
heating). The plenum temperature is still limited by the potentiometer
of the control card.
TWo-STAGe THerMoSTAT
The control card of the furnace auto-detects the two stages of the
thermostat.
W1-
The thermostat closes the R-W1 circuit, which activates the first
stage of the heating sequence (±50% heating). The blower starts up
at low speed and the furnace elements are activated one by one to
reach the adjustable temperature limit set by the potentiometer on the
furnace control card.
If there is still a W1 heating demand after 30 minutes, the heating
sequence continues as per the W2 sequence.
And/or W2-
If the thermostat closes the R-W2 circuit, the sequence
continues as follows: the blower switches to the medium speed and all
the furnace elements are activated one by one (100% heating). The
plenum temperature is still limited by the potentiometer of the control
card.
