Термостат для фанкойла 2-трубный, 3 скорости вентилятора, 24 В перем. тока, серебристый

Digital thermostat for 2-pipe fan coil system TF243SN-S/U. TF243xx-S is a digital thermostat for fan coil systems with comfortable climate control and flexible mode settings. The TF243xx-S series model is designed for controlling a 3-speed fan and modulating water valve in fan coils, including cooling/heating depending on the configuration. The device supports scenarios of 2-pipe systems (cooling or heating - in the mode available for a specific assembly/setup), ventilation mode, as well as functions that enhance power grid stability and ease of use. Key control features: 2-pipe system: cooling only / heating only / manual changeover; Ventilation mode for maintaining set conditions and air circulation; Manual or automatic control of 3-speed fan; Control of modulating water valve for precise thermal power adjustment. Functions for reliable operation and savings: In addition to basic control algorithms, the TF243xx-S series offers additional modes that help optimize equipment operation throughout the season and increase power supply stability. Random Start-up helps reduce peak loads on the power grid when the system is turned on; Memorized time off: memorizing the power-off time; Energy-saving mode (optional); Freeze protection to prevent critical conditions; Setpoint limitation for correct operation and ease of use. Display, interface, and ease of setup: Information about parameters is displayed on an LCD with a simple user interface. Room temperature or setpoint can be displayed depending on preferences. LCD with intuitive interface; Display of room temperature or setpoint (selectable); Selection of fan speed: manual or automatic (selectable); Temperature measurement units - °C or °F; Saving user settings during power loss; Keypad lock options. Sensor and control options: Remote temperature sensor available as an option; Additional control scenarios for modes and ventilation depending on system setup. Operating conditions for humidity: For stable operation, the thermostat is designed for operation in a wide humidity range (without condensation): Min. humidity: 5% RH, non-condensing; Max. humidity: 90% RH, non-condensing. Where it is applied: TF243xx-S is suitable for controlling fan coils in spaces where precise temperature adjustment and flexible ventilation control are required. The device will be appropriate in heating/cooling systems of various purposes - from commercial objects to residential spaces (within compatibility with the 2-pipe system configuration and type of actuators). How to buy Resideo (Honeywell) correctly: It is important to purchase Resideo (Honeywell) equipment from an official dealer - LLC Promelektronika (sales@prom-elec.com) to receive correct delivery support and equipment compatibility assistance. Also note: Resideo (Honeywell) equipment is still being supplied in full to Russia. Conclusion: Thermostat fan coil 2-pipe, 3-speed fan, 24Vac, Silver (TF243SN-S/U) is a digital solution for comfortable fan coil management with clear settings, protective functions, and energy consumption optimization capabilities, including Random Start-up mode.
