ECtemp 535
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.

lower temperature (also called economy temperature) and
periods with comfort temperature.
Using the Timer Function
In order to automatically switch between comfort temperature and economy temperature (e.g. when going to bed or
to work), the timer function is used. A status bar in the bottom of the display gives an overview of timer status.
