Abstract
A modulating heater system for a pool or spa includes a pool/spa heater capable of variably modulating energy output thereof and a controller communicatively coupled to the heater. The controller determines a current mode of operation for the heater, and establishes temperature overshoot and target temperature setpoints for pool/spa water for the current mode of operation. The controller determines a current temperature of the water, an optimized modulation rate for the heater for the current mode of operation, and a maximum modulation rate for the heater for the current mode of operation. The controller controls the heater to operate at one of the optimized and maximum modulation rates based on the temperature overshoot setpoint for the current mode of operation, the target water temperature setpoint for the current mode of operation, and the current water temperature. A corresponding method for controlling a pool/spa modulating heater is also provided.
