Thermostat-controlled heating ventilation: pre-heating of electric heater.
If the electric heater is used
(whether as a supplement or replacement) the timing takes into account the need to prevent the
electric heater remaining at high temperatures for too long. When the electric heater is turned on, a
pre-heating phase begins (30 seconds at V
1
) before arriving at full capacity. When the electric
heater is turned off, the fan stays active for another 30 seconds (post-ventilation):
