Problems White Rodgers 1F35-910 to Hunter 44155C (3 Wire in the wall)

Old Thermo: White Rodgers
New Thermo: Hunter 44155C

I have a oil burning furnace with 3 zones using 3 wire thermostats from white rodgers. The colors in the zone I am replacing are White, Red, and Green.

On the old thermo 4 = Green, R5 = Red, and Y6 = White. I have setup Red on the new thermo to RC/RH, Green to O, and White to W/B.

Yesterday the valve stayed open and this morning it wont open even though the thermostat says its calling for heat.

The hunter is not made to operate a 3 wire zone valve.

Stats I would recommend for your setup

WIFI stat - RTH6580WF or RTH8580WF

Programmable - RTH6350D, RTH6450D, RTH7500D, RTH7600D, or RTH8500D

NON-programmable - RTH5100B, or RTHL3550D

Tonight in looking at the system, the zone valves have TWO white wires, one person told me it was a 3 wire system, but just the thermostat was 3 wires, and the actual valves are two wire.

Does this make any difference?

yes, that makes a difference. What is the model number of the zone valve? How are the thermostats wired? How is the system wired. Zoned systems can be difficult for homeowners to understand the wiring on.

The old thermostats are for 3 wire zone valves.
