5. OPERATION Thermal Performance During severe weather the thermostat actually controls closer to the setpoint than a electromechanical control This is because the heat anticipator is replaced by two electronic control strategies cycling by heat anticipation and proportional plus integral control Electronic cycling by heat anticipation acts like a traditional heat anticipator except that it never needs adjusting for various control circuit load currents It cycles off the heating system slightly before the room temperature reaches the setpoint to keep the heat remaining in the ductwork from overheating the room In severe weather a conventional control with a heat anticipator tends to turn off the system too soon so the effective setpoint is somewhat below the setpoint In very cold weather the difference between setpoint and effective control point can be 5 F or 6 F 2 C or 3 C with a conventional control This phenomenon is called droop Proportional plus integral action eliminates droop by adjusting the on time of the stage that is cycling longer or shorter until the control point matches the setpoint The thermostat maintains the space temperature within 1 F of the setpoint The zero droop performance provides improved occupant comfort and energy savings Occupants do not need to continually adjust thermostat settings to maintain desired temperature even during severe weather Operation Sequence The thermostat energiz
