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 rst
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.

OPERATION
1. CONTINUOUS VENTILATION button: Allows the selection of the
high or low speed continuous ventilation mode.
2. LOW SPEED CONTINUOUS VENTILATION green LED: Indicates
that the low speed continuous ventilation mode is activated.
3. HIGH SPEED CONTINUOUS VENTILATION green LED: Indicates
that the high speed continuous ventilation mode is activated.
4. MODE button: Allows the selection of the Standard or Eco mode.
5. STANDARD MODE green LED: Indicates Standard mode is
activated.
6. ECO MODE green LED: Indicates that the Eco mode is activated.
7. CONTINUOUS HEATING button: Allows the selection of the
maximum or minimum continuous heating mode.
8. MIN CONTINUOUS HEATING green LED: Indicates that the
minimum of heating capacity is activated.
9. MAX CONTINUOUS HEATING green LED: Indicates that the
maximum of continuous heating mode is activated.
10. THERMOSTAT yellow LED: Indicates that the furnace is receiving a
heating demand from the thermostat.
