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 temper-
ature drop in the room will also be detected. Instead of im-
mediately switching on the heating to compensate, infor-
mation is stored and a check will be made to detect wheth-
er this sudden drop of temperature may be caused by, for
instance, a window that has been opened for 10 minutes.
