Honeywell TF228wn Digital Fan Coil Control Thermostat

>>General Application                                     
 
The TF228WN digital thermostat is designed for 3-speed fan and valve control in a fan coil system, including:
2-pipe cool only/heat only/manual changeover
Ventilation mode
Manual or automatic 3-speed fan control
Water valve control
Besides the basic controls, TF228WN featuring CPH (Cycle Per Hour) better maintains the room temperature to the setpoint
and memorized time off function can automatically turn off the thermostat to save energy.
In addition, Honeywell Random start-up function would help to maintain power grid stability.
