connection a learning nest to a water furnace intellizone zone controller

landis — Wed, 22 Dec 2021 11:18:41 GMT

The connections from the zone controller are

R - C - Y1 - Y2 - Y3 - O - G

Y3 is connected to W2.

The problem is the furnace never goes to into stage three heating.

The Y1 - Y2 are the only wires that come on

the chart included in the zone controller

operation modes Y1 Y2 W O G

Heating 1st stage on off off off on

Heating 2nd stage on on off off on

Heating 3rd stage on on on off on

Heating Emergency off off on off on

Cooling 1st stage on off off on on

Cooling 2nd stage on on off on on

Constant Fan off off off off on

Any suggestions on how to get the thermostat in to 3rd stage heating
