Hi
I want to replace an hold whiterodgers thermostat 1e30-910 with a honeywell RTH230B for
Oil heating system.
There are two wires for the old one, one is connected to a point marked with R5 which is connected with a white wire to the mercury "bulb". The other is marked with 4 and is connected to the middle of the thermostat.
Which of the wires I connect to W and which to Rh?
Thanks, kobics
