The PX ECO2S PRO Smart Wall Heater, delivers next-level comfort control with the powerful ECO PRO Remote Thermostat, featuring a 7-day programmable heating schedule that puts personalized comfort right at your fingertips. Simply set different heating profiles for each day of the week, aligning comfort with daily routines while optimizing energy efficiency.
At the core of the system is the original ECO2S electronic controller, which ensures consistent warmth by minimizing temperature swings. During colder periods, it delivers full power to heat the room quickly, then automatically reduces wattage to maintain the set temperature while saving energy.
The ECO PRO Remote Thermostat, equipped with an integrated temperature sensor, can be placed anywhere in the room to eliminate cold spots and ensure precise temperature control exactly where it’s needed. Additional smart features include summer fan-only and timer modes, remote temperature adjustments, and King’s exclusive Pic-A-Watt heating element, allowing installers to easily select the ideal wattage during setup. An integrated BMS lockout circuit enables seamless integration with Building Management Systems, preventing the heater from operating during cooling cycles.
The PX ECO2S PRO is also compatible with optional wired or wireless RF window/door and occupancy sensors, automatically setting back temperatures when windows are open or when the room is unoccupied. With its intuitive programming, energy-saving design, and advanced sensing capabilities, the PX ECO2S PRO redefines smart electric heating with comfort that adapts to your life.
