Product Description
The TF628 series digital thermostat is designed for 3-speed fan and on/off valve control in a fan coil system, including:
- 2-pipe cooling only/heating only/manual changeover
- 4-pipe cooling/heating manual/auto changeover
- Ventilation mode
- 2-stage cooling application (only activated under cooling system type)
- Manual or automatic 3-speed fan control
- On/off water valve control
Besides the basic controls, TF628 series featuring CPH (Cycle Per Hour) better maintains the room temperature to the setpoint and Random Start-up Function would help to maintain power grid stability. In addition, Honeywell Memorized Time Off Function can automatically turn off the thermostat to save energy.
