Marley explains the working of the high output FSSHO Digital Wall Heater

SmartSeries® fan-forced wall heaters provide the ultimate integration with the building's climate system. The LED touchscreen-enabled programmable thermostat offers a control lockout feature so temperatures stay set at the level one controls. Plus, the unit is compatible with a Building Management System (BMS) for easy monitoring and operation from a central location. Its augmented 4000-watt heat level makes it suitable for big rooms.

FSSHO - High Out-Put Digital Wall Heater provides precise heat within 1.5 degree of set temperature (as compared to five degrees with conventional bi-metal thermostats). Provides only the amount of heat needed at any given moment by continually calculating heat output and fan speed of the proportional difference between room temperature and the set temperature.
