How do you set the heat anticipator on a thermostat?

Set the thermostat’s system switch to the right, or ‘Heat,’ setting if the unit is fitted with a sub base. Adjust the thermostat dial until the setting exceeds room temperature; the system should start blowing hot air. Adjust the dial to below original room temperature; the heating system should stop blowing hot air.

How do you test a heat anticipator?

How to Make the Correct Current (Amps) measurement at the thermostat heat anticipator. Turn power on to the heating system. Run the heat for at least five minutes to warm up the system to normal operating temperatures. Remove the thermostat cover (if necessary) to expose the R and W terminals.

Is the heat anticipator powered during the heating cycle or during the off cycle?

In order to keep the room from becoming much hotter than the thermostat set point, a heat anticipator turns off the heating boiler ahead of time or before the room temperature has actually reached the thermostat set point.

Does a digital thermostat have a heat anticipator?

Digital thermostats do not use an anticipator setting. As received, a digital thermostat will provide very accurate temperature control and does not use an anticipator to control temperature.

How does a thermostat heat anticipator actually work?

How the Heat Anticipator Works The heat anticipator essentially consists of a small disc attached to the bimetallic coil of the thermostat. The disc has a thin wire on its surface and an adjustment arm that touches the wire. The position of the arm determines the electrical resistance of the wire, which in turn affects how hot the wire gets.

What should the heat anticipator be set at on the thermostat?

The heat anticipator on the thermostat should be set to match the requirement & electrical characteristics of the particular heating or air conditioning control circuit that it is switching on and off. Useful References for Thermostat Heat Anticipators

What is the purpose of a cooling anticipator?

A cooling anticipator generates a small amount of additional heat to the sensing element while the cooling appliance is not operating. This causes the contacts to energize the cooling equipment slightly early, preventing the space temperature from climbing excessively.

What does anticipator do?

Properly adjusted a heat anticipator also prevents the room from getting warmer than the thermostat set temperature, and it prevents the heat from shutting off before the room has reached the thermostat set temperature.
