Are the cycle rate switches both set to "On"? That will allow 1 cycle

This thermostat has DIP switches.

There are 2 of them. Here are the possible choices:
on/on - steam or gravity (1 CPH)
off/on - high efficiency warm air, hot water, or heat pump (3 CPH)
off/off - gas or oil warm air (5 CPH)
on/off - electric warm air (9 CPH)

Because mine is gas/hot water, I have the second choice above selected.

Should I try the on/on position, then?

Actually, even with that, it's still not what I would prefer.
I want the furnace to come on when room temperature drops to, say, 64
degrees.
I want the furnace to STAY ON until the temperature reaches 70 degrees,
then shut off until the temp again drops down to 64.

Are there any thermostats that can do that?

Well, according to the article I cited Honeywell works a bit
differently
than all Lux thermostats and the Hunter 44550 Auto Save.

"All Lux Products thermostats come with swing control as does the Hunter
44550 Auto Save. What is a mystery to those looking at thermostats is
why there is no swing control on Honeywell thermostats. It is not a
simple oversight on Honeywells part. Honeywell is one of the earliest
makers of control technology for the home and they have deliberately
done away with the idea of swing control."

That's right, at least with the Honeywell thermostats that I've used recently. They set the number of cycles per hour desired, not a temp swing range. I'd be surprised if even an old mercury thermostat with a heat anticipator could do a 6 deg swing. Nor do I see why anyone would want it. I'd call that a busted thermostat.
