ECtemp 550
1 Introduction
ECtemp 550 is an adaptive temperature controller specially
designed for floor heating systems by using the built-in
room sensor and an external floor sensor . It can, however,
also be used for other heating systems (e.g. power heating
units).
The thermostat will measure the radiant temperature from
the floor combined with the air temperature in the room to
compensate for the outside weather condition. This means
that ECtemp 550 will automatically adjust the heating to
meet your comfort levels regardless of changing weather
conditions shortly after the settings are set and the desired
comfort temperature has been selected. A sudden temperature drop in the room will also be detected. Instead of immediately switching on the heating to compensate, information is stored and a check will be made to detect whether this sudden drop of temperature may be caused by, for
instance, a window that has been opened for 10 minutes.

Even the programming of economy temperatures (i.e. lowering of temperature at night and when you are at work) is
very simple. A calculation of the heating start is not needed
to reach a specific temperature at a specific time. Just tell
the ECtemp 550 when you want the comfort temperature,
and the rest will happen automatically; by identifying the
rate of heat loss from the room, ECtemp 550 knows when
to start heating in order to achieve the selected temperature at the right time.
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 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
regulations.
