Pro 1 Thermostat Wiring Diagram - When in cooling mode, the furnace doesn't generally do a good deal at all. Whilst the thermostat is simply too warm, it generally energizes each the y and g terminals (in case you're the use of a warmness pump, the o and/or b terminals could also be energized). The y terminal tells the condensing unit (or heat pump) to turn on, even as the g terminal tells the furnace to turn at the blower (once more, at excessive speed). What i am finding odd is while the heating kicks on, it activates separately of the fan. But i can nonetheless turn the fan on whilst the furnace is jogging. Is the secondary fan the blower motor for the furnace and is there any threat of going for walks each the fan and furnace on the equal time.
While the fan activate the thermostat is switched to the on position, the thermostat energizes the g terminal. This tells the furnace to turn the blower motor on. If the furnace is ready with a multi-pace motor, the motor will usually be in excessive velocity while the g terminal is energized. There are minor issues with having the fan activate whilst in heating mode, but both are more related to performance than whatever else. First, remember the fact that while in heating mode, the furnace has a postpone before turning on the blower. This delay is vital, as it allows the furnace to heat up earlier than it starts blowing. If there is no put off, the furnace will begin blowing cool air around, and could take longer to reach height operating temperature.

When in heating mode, the furnace itself controls the blower. While the thermostat receives bloodless, it calls for warmth by using energizing the w terminal (in case you're the usage of a warmth pump, the o and/or b terminals will be energized as nicely). While this happens, the furnace initiates the firing collection. The furnace will try to fireplace up, and if a hit, will turn the blower on after a timed delay (20-30 seconds normally). When in heating mode, the blower will normally run at a slower speed (low, med lo).
