Digital thermostat for fan coils 2-pipe system: TF243DN-S/U (black)

Resideo (Honeywell) TF243xx-S — this is a digital thermostat for controlling the operation of fan coil in a two-pipe system with a 3-speed fan. The model is designed for cooling/heating tasks (depending on the mode) and provides precise maintenance of parameters in the room thanks to support for controlling modulating water valve and various energy-saving and protection functions.

This thermostat is a practical solution for engineering systems where stability of the power supply, ease of control, and the possibility of fine-tuning operating algorithms are important.

Key features of the TF243xx-S series

• 2-pipe scheme (cooling only / heating only / manual switching)
• Ventilation mode
• Control of a 3-speed fan: manual or automatic
• Control of modulating water valve for smoother regulation
• Random Start-up Function — helps maintain the stability of the power supply during turn-on/recovery of power

User control and convenience functions

• Time-off memory (Memorized time off)
• Random start-up (Random startup)
