ECtemp 535 Introduction ECtemp 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 weath- er conditions by measuring the floor temperature and com- bining it with the room temperature.
ECtemp 535 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 tempera- ture correctly.
