Changing over from a White Rogers Thermostat model 1F78-151, which is a single stage thermostat for heat only. What Honeywell Thermostat is compatible with this brand?

Thanks,
Ruth

Good basic honeywell is a t87 heat only stat, or a really good honeywell is the pro 5000 wich can be set up for a number different systems including heat only. Just read the instruction manual for setup and you will be a happy customer

If you have 2 wires coming out from the wall & the voltage across these wire is between 24-30Vac.. then in that case you can use the following stat-
Programmable stat-
RTH230B (Digital)
RTH6450/RTH6350
RTH7500/RTH7600

Non Programmable Stat (Digital)
RTH5100B

Mechanical Stat-
CT87K / CT87N

All these thermostat are easily available in stores like home depot ,Lowe's etc... But the voltage across these wire (That are coming out from the wall) should be between 24-30Vac
