Please attach a photo to a comment giving us an image of your White Rodgers 1H series thermostat and additional photos of any labels or markings on the thermostat including inside its cover.

While we have no trouble finding White Rodgers 1E series and 1F series and other thermostat models I've not found the one you cited.

The Honeywell Pro 3000 is a non-probrammable wall thermostat.

The White Rodgers 1F35-910 is a (now discontinued) wall thermostat designed for three-wire zone valves.

I don't understand why you would be trying to connect one thermostat to another. So I suspect I don't have the right understanding of your question.

Zone valve wiring instructions for pretty much all types of zone valves begin at

ZONE VALVE MANUALS & WIRING INDEX

The manual for your Honeywell Pro 3000 thermostat gives the proper wiring connections and is at

https://customer.honeywell.com/resources/techlit/TechLitDocuments/69-0000s/69-1929EFS.pdf

Below is an example of a simple 3-wire Flair zone valve illustration widely found across the web at sites that I see have lifted the illustration from our original work.

Trying to connect a White Rodgers 1F35-910 (Red wire (W4), white wire (R5) and Green Wire (Y6) to a Honeywell Pro 3000. I connected the Red to W, White to R/Rc (jumper) and Green to G. Hot water boiler system.

The boiler furnace stays on for 15 secs, then shuts off. Does this repeatedly. But doesn't with the mercury. Is there something else I need to do?

Question: Replacing a round Honeywell T87 with a Digital Honeywell Thermostat

Hello - I am replacing a round Honeywell thermostat with a non-programmable digital Honeywell unit. I have a hot water system with multiple zones and with no air conditioning.

There are three wires at the thermostat. On the old round unit the red wire went to the R terminal, the white wire went to the w terminal and a green wire went to B terminal. I hooked up the new stat the same way but it would not work.

If I selected "fan on" instead of "fan auto" the zone would heat up but would not shut off (hot water kept flowing even if I selected a temp below room temp). Appreciate your help. - Patrick - 1/20/12

Reply:

Patrick, typically the three wire thermostat hookups would be exactly the same for the old and new thermostats.

For details of wiring a typical and simple digital Honeywell thermostat,

see Honeywell 5-2 Day Programmable Thermostat - RTH2300B1012.

Kurt, as you see in the examples at For help in understanding the wiring of your old thermostat,

see Three-Wire Honeywell Wall T87-F type Thermostat wiring and also

see Generic HVAC Thermostat Control Wiring Points.

Many thermostat wiring setups are straightforward or "cookbook" but why not find the brand name on your thermostat and then you can obtain the installation instructions right from the manufacturer?

Also, Honeywell's thermostat replacement advice (and most likely that of all thermostat manufacturers) warns:

Watch out: MERCURY NOTICE: Do not put your old thermostat in the trash if it contains mercury in a sealed tube. Contact your local waste management authority for instructions regarding recycling and proper disposal.[5]

Question: Lennox conversion to White Rodgers TT

(Nov 22, 2014) Dale said:

I have a old lennox 2wire red and white wires from the old thermostat I bought a white rodgers up400c thermostat where do I install the red and white wires to my new thermostat

Reply:

Dale that's tricky since you describe 4 wires, 2 red and 2 white we don't know which does what without doing some testing.
