central zone control

KBP&H

what it would do is add whatever heat is required uo to the thermostat setting-// 1/2*//3/4* or whatever,, so that the boiler would stop bouncing around off seperate zones, and thus running at rated output for only one zone, similar to warm air,, but still seperate.. It would that this would add to efficency since the boiler would be running at mostly full load, and start much less often w/ longer run times.???? Dan- some input______

central zone contol

??? Does anyone make a control / s that would link all hot water zone thermostats together so that when one or primary zone calls for heat, all of the zones would be turned on and then each would drop out as each zone temperature is satisfied.

Why would you want to open a zone that is not calling for heat?

Why not just put in Outdoor reset

Under most conditions most of the zones will be open providing for nice long burner run times.

You can use a Tekmar 371, It will handle five zones with indoor and out door temperature feedback. This control will reset boiler temp based on outdoor and indoor temp, It will also stagger the zones on and off to make your boiler run longer alleviating boiler short cycling.

if you are having that much boiler bouncing on and off that seems to indicate very small zones. a buffer tank could help this situation, or maybe you just went hog wild on zoning. outdoor reset would definately help and probably be a nice payback.
