Thermostat control head with liquid probe, consisting of hand wheel with scale and base in different colours (see ordering table). Optional version with remote probe or remote adjustment. The desired room temperature is set with the hand wheel. The temperature probe continuously checks the room temperature, compares the measured values to the set value and controls the flow rate by opening or closing the valve to obtain the set value. Adjustment range can be limited and blocked with a ring. With optimum temperature position (eco position) adjustable via memory clip (helpful for persons with visual impairment). Frost protection position with snowflake symbol.
Tamper-proof version without zero position. Lower adjustment only to snowflake symbol. The adjustment range must be selected when the valve is mounted for the first time. A protective cap consisting of two parts which cannot be removed prevents disassembly and changes to the selected settings. The protective cap is secured by means of a screw.
