Heating Zone keeps coming on (stuck)

Hi Everyone,

We have Amana Natural Gas furnace model DMS91155DXA - with 2 zones. 2 story house - live in New England.

Our thermostats Lux PSP511LCa. I did change the batteries in the Zone 1 thermostat.

Zone 1 works normally when the Zone 1 thermostat calls for heat and shuts off appropriately.

But when Zone 2 calls for heat, Zone 1 comes on - even if the Zone 1 thermostat is shut off.

Fortunately Zone 1 is downstairs and Zone 2 is upstairs - so zone 2 stays warm. But zone 1 is gets a bit toasty waiting for the heat to rise.

Any help would be appreciated!
