object Actual value
Cheops control can obtain its
actual value from three
sources. Selection can be
made from 2 such sources:
fitted sensor
bus (Object 2).
An external sensor can be
selected via the "Function of
external interface" parameter
on the Settings parameter
page. In this case, there is no
option to select between
internal sensor and actual
value object.
Temperature offset for

(in 0,1K, -64...63)
Manual input -64.. 63
Positive or negative
correction of measured
temperature in 1/10 K
increments
Example: Cheops sends
20.3°C. A room temperature
of 21.,0°C is measured using
a calibrated thermometer. In
order to increase the
temperature of Cheops to 21
°C,
an "7" (i.e. 7 x 0.1K) must be
entered.
Cheops sends 21.3°C. 20.5°C
is measured. In order to
reduce the temperature of
Cheops to 20.5 °C,
an "-8" (i.e. -8 x 0.1K) must
be entered.

Is the current room
temperature to be sent?
If so, from which minimum
change should this be sent
again?
This setting keeps the bus
load as low as possible.
