Information - CHR room thermostat

The CHR is the recommended electronic room thermostat
for InLine comfort panels.
The CHR is a PI-regulator with a small P-band, suitable
for fast reacting systems. It measures and determines the
room temperature by controlling the rpm of the fan mo-
tor and hence the panel's heat effect.
The CHR is equipped with a boost function that tempo-
rarily increases the fan speed and thus ensures quick
heating.
The heat effect to a room will turn off, when switching
off the thermostat (""). The installation will remain
protected against frost.
