11.4.1. TRANSITION TO AN AUXILIARY HEAT SOURCE

When there is a demand for heat, the furnace checks the temperature in the plenum. If the temperature is beyond the

KIP, the fan will turn on. If the temperature is below the KIP, the furnace will wait the "Rise Time" delay and check the

temperature again in the plenum. If the temperature in the plenum goes up 20°F but has not reached the KIP, the

furnace will wait for additional time ("KIP Time") and recheck the temperature in the plenum. If the temperature has not

reached the KIP, the auxiliary heating will start. The icon "Wood" will turn yellow and the auxiliary heat icon will turn

green.

For the electrical element, the fan starts as soon as the thermostat asks for heat. In other words, for safety reasons,

the fan does not wait for the hot air plenum to reach a predetermined minimum temperature.

The furnace remembers what heating source was used in the last request of the thermostat. If the last heating demand

was met by the auxiliary heater, the furnace automatically start this one.

To restart the furnace using the wood mode, go on the touch screen on the main page and press on the wood icon.

The icon will become green and the auxiliary heating source icon will become yellow.

It is possible to slightly adjust the transition settings from the wood option to the auxiliary source of heating. To do this,

go to the "MAIN" page on the touch screen under the "SETUP" option and choose "WOOD SETUP ". On this page,

you can change the KIP, KOP, the Rise Time and KIP Time.

KIP (Kick-In point): Temperature of the plenum where the fan turns on.

KOP (Kick-Out point): Temperature of the plenum when the fan stops.

Rise Time: Time allowed for plenum temperature to increase by 20 ° F.

KIP Time: Additional time allowed to reach the KIP when the Rise Time ended with an increase of 20°F.

If you have configured one or many auxiliary heating sources (electrical element, heat pump), you must choose the

priority order when there is a heating demand. If, for example, the wood no longer provides sufficient heat, the auxiliary

heating selected in priority one will take over. If priority one no longer provides enough heat, or does not provide it fast

enough, priority 2 will take over. Heating priorities are chosen in the "MAIN" menu, under the "SETUP" option. Select

"OPTIONS" and "CONFIGURATION". Use the arrows to select the priority order.
