Product Description

The TF228WN digital thermostat is designed for 3-speed fanand valve control in a fan coil system, including:
• 2-pipe cool only/heat only/manual changeover
• Ventilation mode
• Manual or automatic 3-speed fan contro
• Water valve control

Besides the basic controls, TF228WN featuring CPH (CyclePer Hour) better maintains the room temperature to the setpoint and memorized time off function can automaticallyturn off the thermostat to save energy.

In addition, Honeywell Random start-up function would helpto maintain power grid stability.
