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. 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.

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.
▪ 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
regulations.
The thermostat has a safety
switch. When turned off, all
electrical supply to the thermostat is disconnected.

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.
