Honeywell TF228WN Digital Thermostat
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 set-point 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.
