an npn transistor has 3 pins the emitter base and collector and basically you would take the two pins from where the button should be and connect the emitter and collector (outermost pins) to them then the center pin (the base) goes to an arduino pin and if you pull that pin high then the outermost pins will be connected
they can be bought here
check the datasheet for more information
I will. Is this an acceptable mosfet? IRF5210 P-Channel Power MOSFET Transistor 100V 40A 60m Ohm https://www.amazon.com/dp/B00HR6AWPI/ref=cm_sw_r_udp_awd_.FA2tb0J9P8B8P9W
So This would work?
I'm not sure if you're looking for something specific, but this is what I found:
https://amazon.com/dp/B07SQBRTZC/ref=cm_sw_r_cp_apa_i_7rlPDbVCD42C7
https://www.amazon.com/20PCS-J201-AMP-N-CHAN-50MA/dp/B01680YTKC/ ...0.45 each. I sample-tested a few and they seemed all right.
IMO For testing NJFETs, you really do need at least the runoffgroove test jig. Operating at 9V, the numbers it yields won't always agree with the specs in the datasheet which are derived in a test circuit operating at 15V as declared... but the pedal you'll be using them in runs on 9V anyway, so the test-jig results are "news you can use", whether it's for setting up a Fetzer stage or seeing if you can fully pinch off a gain-control element.
Why not just buy some? This for ex: https://www.amazon.com/Hilitchi-250-Piece-General-Transistors-Assortment/dp/B06Y4M2N29/
​
250 assorted types for $10 is 4c a piece... not worth the time in my mind.
2N7000
100 pcs of 2N7000 MOSFET N-CHANNEL 60 Volts 0.2 Amps https://www.amazon.com/dp/B00KLBGJL2/
Notice they are not very high power though. I got them for 3.3 to 5V logic level conversion, not power switching, and didn't plan to use them with anything close to 200mA.
So probably not the best thing but I figured I'd mention it anyway.
OK, here is the manual for your boiler. https://www.alpinehomeair.com/related/Burnham%20Series%202%20Install%20Instructions.pdf
It does specify dry-contact connection for the thermostat (Signified by the T/T.) So I would suggest purchasing a SPST-NO or DPST (using only NO side) isolation relay such as this https://smile.amazon.com/Industrial-Grade-6AZU2-Enclosed-Relay/dp/B004ZROX4S/ref=pd_sbs_328_3?_encoding=UTF8&pd_rd_i=B004ZROX4S&pd_rd_r=NJSDMWMAR76X8GT665ZX&pd_rd_w=wmjFk&pd_rd_wg=JJH7c&psc=1&refRID=NJSDMWMAR76X8GT665ZX#detail-bullets
Regarding your air handler, most likely it does not have a R,C,W,Y,G terminal block, but has a wire bundle coming out of it to which the thermostat wires are nutted. Can you look for that and take a picture? Also, tell me the make/model # of your air handler so I can look up the manual.
