Operation Functions
1. Core Control
– Valve Regulation: Controls hot water flow to radiators/floor pipes based on room temperature vs. setpoint.
– Heating ON when room temp < setpoint; Valve closes when temp ≥ setpoint.
2. Safety Protections
– High-Temp Cutoff (60°C): Auto-shuts valve if floor sensor ≥60°C.
– Sensor Failure: Displays Err/ E1/ E2 and locks heating output.
– Frost Protection: Forces heating ON if room temp < user-defined threshold (e.g., 5°C).
3. Programming Features
– 5+2/7-Day Scheduling: 6 time periods per day, separate settings for weekdays/weekends.
– Economy Mode: Pre-set energy-saving temperatures for unused periods.
4. Advanced Operations
– Key Lock**: Long-press ▲+▼ for 5s to enable/disable child lock.
– Floor Temp Display**: Long-press ▲ for 5s (dual-sensor models only).
– Advanced Settings**: Long-press Mode+Clock for 5s (off state) to configure:
– Frost protection threshold
– High-limit temperature (AL function)
– Sensor calibration
5. Technical Safeguards
– Low-Temp Auto-Start: Activates heating below user-set frost threshold.
– Post-Failure Recovery: Resumes operation only after fault clearance (e.g., sensor replacement).
