Heating Zone Question

[timalabim]

I currently have 2 Zones plus a water heater loop off my Forced Hot Water Burnam Furnace. Zone 1 is the original Main house, and Zone 2 is finished area of the basement.

I recently added a pellet stove which is doing a nice job keeping Zone 1 warm. I have a programmable thermostat for the Pellet stove set up right next to the programmable thermostat for Zone 1 so that unless there is a point when the pellet stove can't keep up, the Zone 1 thermostat doesn't call for heat. Currently the only exception is when the setting rolls over from from 62 to 68 in the morning. The 15 minute head start I gave the pellet stove isn't quite enough to keep Zone 1 from calling for heat for a half hour or so. Other than that Zone 1 never calls for heat.

My issue is that I notice when Zone 2 (the Basement) is calling for heat, the radiators in the Zone 1 heat up. Enough for the kickspace heater in the kitchen to run its fan. I can't really tell if the circulator pump for Zone 1 is running when this happens as the two pumps are very close together and I'm not sure if the vibration I feel is just physical transfer, although I think that it
is running since I don't think a convection flow would give enough heat to get the kickspace heater enough heat to kick on it's fan.

What step should I take to check this out? I am not at all familiar with how the Furnace controller works, but if there are standard wiring configurations I could look at or where I should check for voltage output I could figure it out. I don't have the
controller info with me, but I believe it is a Honeywell unit. I can get the specifics if that would help.

Do you have a volt meter to see if both circs are indeed running? That's where I would start...see if your zone 1 is running when it shouldn't be.

Ayuh,...

And,.. Are Both circulators controlled by the Same Honeywell controller,..??

Yep, actually all 3 circulators( zone 1 , zone 2, water heater loop ) are on the same controller.

Yup, when zone two is calling, check with ammeter or volt meter to see if zone one pump is running. It should not be. If it's not, next thing to look at is the flo-ckeck.... you do have flo-checks don't you? If you don't, that's the problem. If you do have flo checks, make sure they are closed. On the top of each is a wing nut, or allen screw, looking down from above, all the way clockwise is the "run" position. If it is turned 3 or 5 turns counterclockwise they will bypass water when the other zone is calling.
