1 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 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. Just choose the programme that fits your daily rhythm best.
Furthermore, the thermostat features a minimum floor
temperature setting, eg. for keeping your tile floors warm
in summer as well.

Do not spill liquids of any kind into the thermostat.
▪
Do not open, disassemble, or tamper with the thermo-
▪
stat in any way.
If the thermostat is installed in a place frequented by
▪
small children, use the safety lock.
Do not interrupt the power supply to the thermostat.

The installation of the thermostat must be done by an
▪
authorized and qualified installer according to local
