I actually have a transformer which could with the humidifier, need to i join this unit as properly?. Its generally the crimson twine this is at the motor, if you have a circuit board in your unit it will be the one related to a cord tap classified "warmness" , let me realize if yo locate it.
There is two ways to cord this up. The primary method is to take advantage of the hum terminal at the furnace control board. This terminal will supply one hundred twenty volts when the furnace is running in warmth mode, so you'll must use an extra transformer. With this setup, you will join the 24vac terminals of the humidistat to the c and w terminals at the furnace manage board. That manner when the thermostat calls for warmth, the humidistat could be powered by using the furnaces transformer.
The furnace works first-rate! However: q1. How do i understand which humidistat wires to connect with furnace manage board terminals? Q2, q3. Precisely which terminals at the furnace manipulate board - which of them and how?. A fan powered humidifier generally has an on-board transformer, allow me take a look at the manual once more, i'm able to need to go away for some time although as i am out of time for this morning, i will be back later today.
