A Heat Anticipator is really a potentiometer connected to (possibly) two resistors. You may see these resistors behind a mechanical thermostat "coil". When the heater is running, current flows and heats up the resistors, making the heater turn off a little early so that it doesn't overshoot the temp you have set. If the pot is set at it maximum resistance, the resistors heat less, it just makes sense. Check your manual on your thermostat for proper settings.

What are three kinds of switching mechanisms used in low-voltage thermostats?
Mercury Bulb, heat-anticipator and a cold-anticipator.
How is a heat anticipator wired in a system?
A heat anticipator is wired in series with the thermostat heat call circuit. It is typically connected to a bimetallic coil within the thermostat that adjusts the temperature at which the heating system turns off, preventing overshooting of the set temperature. The anticipator helps the system maintain a more consistent temperature by fine-tuning when the heat shuts off.
What is the disadvantage of a heat anticipator?
A heat anticipator can potentially cause the thermostat to cycle the heating system on and off too frequently, leading to energy inefficiency and wear on the system components. This can result in inconsistent heating and discomfort for occupants.
What type of resistor is the heat anticipator?
The heat anticipator is a resistor that is part of a thermostat control mechanism in some heating systems. It is typically a wire-wound resistor that helps regulate the cycling of the heating system by anticipating the heat demand and shutting off the heating element before the desired temperature is reached.
Is it true or false that a heat anticipator should be set to match the amp draw of all heat relay controls in the control circuit?
True
How should you determined the heat anticipator setting on the room thermostat when using individual sequencers?
To determine the heat anticipator setting on a room thermostat when using individual sequencers, first identify the total current draw of the heating elements controlled by the sequencers. Then, set the anticipator to match the total current in amps, which is usually indicated on the thermostat's scale. This ensures that the thermostat anticipates the temperature change appropriately and prevents temperature overshoot. Finally, make any necessary adjustments based on the system's responsiveness and user comfort.
Furnace heat is sometimes too hot and other times to cold?
First check your thermostat to determine if the anticipator is set correctly and is operating properly.
What is an anticipator?
An anticipator is a device in a thermostat which determines when to turn on or shut off the heating or cooling mechanism.
Inside a GE CHT18-60 thermostat control box there is a toggle labeled longer with the numbers 1 through point 18 what does it do?
Is a slider for the "adjustable heat anticipator assembly"
What helps limit the amount of system overshoot?
A cold anticipator
How should the thermostat be set for gas hot forced air furnace?
In the instruction manual for the furnace, it will either give you the heat anticipator setting or instruct you how to do it. If its digital, well then follow the thermostat instructions
Heat anticipater setting?
Usually refers to the current (AC AMPS) that flows through the thermostat. Use an AC ammeter to measure the current across the (heat) terminals. Usually .1 - .9 AC amps. It is used to fool the furnace to shut off a little early so that the residual heat in the furnace won't increase the room temperature beyond the temperatur setting.
