best way for 2nd circ on Burnham MPO w/ L7248C??
JC from PA
Member Posts: 16
This Burnham MPO I just bought for it's high efficiency has an L7248C aquastat that only works with a single zone? Requiring me to buy a separate relay panel? Why not just sell me the L7248L aquastat with ZC/ZR so I can use an 845 relay!!!??? I'm not using an indirect so there is no priority issues.
Am I missing something here or am I too cheap cause I don't want the extra panel??

Zone Control
Just use a 2 zone circ relay..It is the best and easiest way unless you want to use a couple of RIB relays which will be cheapier.There was an error rendering this rich post.

The 7448 as you know does not have terminals for xr - xc. What you will need to do, as you are familiar with the 845 is to use the #5 and #6 terminals on the 845 as low voltage to the 7248. You will need to disconnect the C1 and C2 and use two 845's.0 -

Adding just one more zone ?
If you're thinking about adding more than the one zone in the future , I'd suggest like the others said and get a multizone relay .
If you're sure it'll be the one extra zone and that's all , a Taco single zone relay is all you'll need . I'm not familiar with that particular model number aquastat , but if it has the ZC / ZR terminals , this should work ...........

Page 89 , " Alternate wiring " .............. that's how we integrate an extra zone into a triple aquastat , and it works well .0
