yes it is compatible to use 24VAC to 24V supply
4.8va/24v = 0.2a
AWG # 14
24VAC used to make dual band 12VAC eg. AC sign wave. one is negative goes up, one is positive goes down. polarities switch and frequency is made and can be tuned. Commercial application: Lots of medical equipment. Seismagraphs.
You will need an interpose relay. This relay will have a 24 volt coil. The circuit power for the relay will come from a 120VAC to 24VAC volt transformer. The 24 VAC circuit will have the thermostat in series with the coil of the relay. Thermostat calls for heat, the coil energizes and the relay's contacts close. Your circulator pump is controlled by the relay. On selecting the relay make sure that the contact ratings can handle the full load amps of the circulator. A contact rating of 120 volts at 15 amps will do very nicely.
Transformer turns ratio is the ratio of voltages between two windings. For instance, a 24VAC control transformer that runs on 120VAC will have a turns ratio about 5 to 1.
you need a step up transformer

24 volts of alternating current
A control transformer marked 240V - 24Vac would have a control voltage of 24 volts.

Most 3 Phase 480V Starters are controlled by 120VAC. This is because the coils on the contactors (starters) are 120VAC. Just ensure the voltage matches the coil.
You would need a 12VDC to 120VAC power supply.
