Key benefits — why you need this thermostat Provides yearround comfort by supporting both cooling and heating modes for fan coil systems, so one controller handles seasonal needs. Saves energy and reduces manual adjustments by automatically controlling airflow and the electric valve based on room temperature. Makes temperature control simple and reliable with clear mode selection, adjustable fan speeds, and builtin scheduling. What it does (core functions) Multifunctional thermostat: select cooling or heating modes to match your system and seasonal requirements. Smart control of airflow: choose , Medium, Low, or Auto fan settings so the thermostat adapts ventilation to current room conditions. Electric valve control: the thermostat opens or closes the valve automatically in response to temperature changes, maintaining the setpoint while minimizing unnecessary energy use. Timing function: program on/off schedules so HVAC runs only when needed, improving comfort and lowering operating costs. How it solves common problems Eliminates frequent manual adjustments by switching fan speed and valve position automatically as the room warms or cools. Prevents wasted energy from continuous operation by timing system run cycles and closing the valve when set temperatures are reached. Reduces temperature swings with coordinated fan and valve control, improving comfort in spaces with variable occupancy or solar gain. Compatibility and performance Designed specifically for use with fan coil units and the electric valves typical to those systems. (Verify electrical and wiring compatibility with your existing fan coil installation before .) Adjustable fan settings and automatic valve control deliver responsive air circulation and dependable temperature regulation without extra user effort. Practical applications (realworld scenarios) Small office: Keep a meeting room comfortable throughout the day. Set a schedule to shut off outside business hours and rely on Auto fan mode for consistent comfort during meetings. Hotel or guest rooms: Provide guests with predictable heating or cooling. Automatic valve control maintains the chosen temperature while timed schedules reduce energy use between checkin/out. Residential apartment with central fan coil: Use heating mode in winter and cooling mode in summer, and program daily schedules so the system runs only when residents are home. What to expect from daily use Simple buttonbased mode selection for quick switching between heating and cooling. Clear selection of fan speeds and an Auto option that adapts ventilation automatically. Reliable, energyconscious operation through coordinated electric valve actuation and timed scheduling. Compatibility note Intended for fan coil systems with electric valve control. Confirm wiring and valve type compatibility with your installer or product documentation before installation.
