To correctly set a heat anticipator, the control amperage reading should be?

The correct method for setting a heat anticipator involves taking the control amperage reading at the thermostat subbase. This is essential because the heat anticipator is designed to prevent the heating system from overshooting the set temperature.

When measurements are taken at the thermostat subbase, they reflect the actual demand and function of the thermostat in controlling the heating system. This ensures that the anticipator is properly calibrated to sense the current draw of the heating system as it operates directly in relation to the thermostat’s settings. By aligning the heat anticipator with the actual power consumption observed at the thermostat, the system can better regulate the temperature effectively and maintain comfort while preventing excessive wear on the heating components.

Measuring at other locations, such as the main power source, burner control, or circuit breaker, would not provide accurate or relevant readings for the specific function of the heat anticipator. These areas do not account for the precise control of heating cycles in relation to the thermostat's operation, leading to potential inaccuracies in the anticipator settings and resulting in an inefficient temperature control system.
