To properly set a heat anticipator, a technician should measure the amps between which terminals on the subbase?

To properly set a heat anticipator, a technician measures the current (amps) between the R and W terminals on the subbase. The R terminal typically represents the power supply from the transformer, while the W terminal is connected to the heating system, specifically to the furnace or electric heat. This measurement is crucial because it allows the technician to determine the load current to accurately set the heat anticipator.

Setting the anticipator correctly is important for the efficient operation of the heating system, ensuring that it cycles appropriately and maintains the desired temperature without excessive energy consumption or short cycling. Measuring between the R and W terminals provides the necessary data to adjust the anticipator to the current draw of the heating system, ensuring optimal performance.
