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.
