:Wow 10 months and I finally do the job. Bob, thanks for the info. It was much appreciated. I do have one more question though. The L8124L aquastat can handle 2 zones. I have 2 Honeywell V8043E zone valves I want to hook up to it but can't figure out the wiring.

: : The above link takes you the manual for this model series. This unit is for when you have a tankless coil plus a hydronic zone or two. In brief, T, TV and Z are in the 24VAC "loop". Around the "loop" it goes: [24 VAC XFRMR] to "Z" to ["1K Relay" (Low Limit/Circ. & High Limit Contacts)] to "T" to [low voltage T-stat] to "TV" to [24 VAC XFRMR]. If you want additional zones they want you to use R845A relay modules. Let me know if you need anything else, or if you can't get the PDF file via the link. - Bob

: My existing boiler has a tankless coil and a honeywell aquastat L8124L. I will be switching to an indirect hot water system by adding another zone and a Peerless Partner 60 gal. tank.
: Can I still use the L8124L as my boiler control after the tankless coil is disconnected?
