New boiler and multi zone relay installed a couple of years ago. The the end switch (X X terminals) are not wired in the relay box and there is a jumper connecting the thermostat terminals (T TV) on the aquastat. Why would it be wired this way?
Boiler: Slant/Fin Sentry S-120
Aquastat: Honeywell L8148E
Relay: Taco SR504-EXP running 4 circulator zones
Please also see my thread about adding another zone relay https://terrylove.com/forums/index.php?threads/adding-zone-relay-advantage-of-taco-expandable.62280/
Thanks
