add transformer to aquastat relay L8148J1009
i have a slant fin GG 125H boiler with 4 V8043E1012 zone valves. the L8148E1273 relay was recently replaced with a L8148J1009 relay which the literature says can only handle 2 zone valves. should i get a transformer which will handle all 4 valves? which transformer and how do i wire it to my aquastat?
L8148J1009 has a T terminal which connects to 1 red wire from each of 4 V8043E1012 zone valves (total 4 red wires). L8148J1009 has a W terminal which connects to each of the 4 t-stats and 1 yellow wire from each of the 4 ZVs. L8148J1009 has a TV terminal which connects to 1 yellow and 1 red wires from each of the 4 ZVs (total 4 red and 4 yellow wires). I am assuming the power for the ZVs is coming from the T and TV terminals (which is getting 24 v from the L8148J transformer). So, I am powering 4 ZVs from the L8148J transformer, right? How do I add a transformer (external to the L8148J) to power the 4 ZVs so that they are not being powered by the L8148J transformer?
help please! thx.0
The L8148J is a Universal
replacement relay and can handle up to five Honeywell ZV's, so you are all set.0
# of V8043E zone valves
well, i wish that were true! the manual tells me (see link below, page 3, table 2) that i can only have 2 zone valves attached before i need to add extra transformer? if I'm incorrect, pls let me know. thx.
Read the footnotes
under the table you can have up to 1.2 amps at 24 volts. Then look up the V8043 and you will find it only draws .3 amps per valve so you can have at least 4 valves off that transformer. Math 4 X .3 + 1.2 amps.0
yes, i did see that..... seems like a contradiction? thank you for your help...0
