IBC boiler remote engineer consult

northlakes

Anyone here have experience with IBC boilers? I've got a system wired up for remote access via the IBC portal and need some help getting outdoor reset curve dialed in. My installer set it to a default reset heating setting but with that it still just cycles every hour.

I've tweaked the curve and and via experimentation was able to find settings that kept zones at a stable temperature, but started having some strange behaviors with boiler going into very short <1 min cycle firing at high btu, then off, with this repeating every few minutes.

I'm assuming it may be due to the settings I've tweaked, but not quite sure why it started doing this suddenly, as it seemed stable for a week or so. If anyone has experience with these boilers please let me know if you're interested.

Tell us more about the system.
Radiant floor? radiator? Baseboard? air handler?
Thermostats?
Zone valves or Circ pumps?
Where is the installer?

Baseboard, thermostats, zone valves, primary-secondary. Installer is in town but I’d say their interest in dialing it in for efficiency is very low.

Call IBC tech support, they will help you I am sure.

Your pumping needs to be right before you can dial in the good curve.

Pumping seems to be fixed now with the replaced circ. Will contact IBC and see how they can help.

One or more of your zones may be too small.
