PRE5104 Temprature Limited Thermostats

This convenient PIR activated electronic three-stage thermostat is one of a sophisticated range of precision electronic controls from Prefect. Ensuring economic energy usage � automatically, the PIR senses when the room is occupied and keeps the temperature comfortable, whilst allowing it to fall slightly to a background level if the room is vacant. If no presence is detected for 48 hours the temperature is allowed to fall to an economical 5�C frost-protection setting. Once the fascia is touched again the unit is re-activated into the comfort / set-back routine.
