DEVIreg™ 535 1 Introduction DEVIreg™ 535 is a electronic timer temperature controller specially designed for floor heating systems. Once set, the thermostat automatically adjusts the heating to meet your comfort levels regardless of changing weather conditions by measuring the floor temperature and combining it with the room temperature. Even the programming of economy temperatures (i.e. lowering of temperature during the night and when you are out of the house) is very simple.
DEVIreg™ 535 1.1 Safety Instructions Please observe the following guidelines: ▪ Do not cover the thermostat, e.g. by hanging towels or similar items in front of it! This will impair the ability of the thermostat to sense and adjust the room temperature correctly. ▪ Do not spill liquids of any kind into the thermostat. ▪ Do not open, disassemble, or tamper with the thermostat in any way. ▪ If the thermostat is installed in a place frequented by small children, use the safety lock.
