Superstor45 not supply enough hot water
recently had a Honeywell L7224 aqua-stat installed. I also have an
indirect water heater installed and Argo ARM 3P Switching Relays With
Priority. My issue is that I am running out of hot water. I have my high
limit set to 190 and my low set to 170 with a differential of 10. My
boiler will not fire up until it goes below the low limit. I would of
expect the boiler to fire up as soon as I it notices that the hot water
heater is in use. I have the arm3p set with priority and wired to the zr
and zc terminals of the aquastat. I was unsure as with on of the
setting. Should the DUU setting be set to on or off. Also, with the
arm3p controller should the boiler turn on when immediately when it is
being called for hot water or should it wait until it hits the low temp
thanks in advance</span>
