Actual MI = The humidity that forms the lower limits of mould growth for the actual
temperature.
The upper curve, the mould index curve, is programmed in HomeVision® and is therefore not
something that is affected by user settings. The user is asked instead to specify the desired safety
margin, upper and lower hysteresis and alarm limit whose meanings are explained using the
following example.
Safety margin, %RH:
‐15%
Activation:
Actual MI
–
Safety Hysteresis Upper =
Hysteresis Upper/Lower:
+ 4%, ‐4%
= Actual MI
–
15% + 4%
Off:
Actual MI
–
Safety margin
–
Hysteresis Lower =
= Actual MI
–
15% - 4%
Alarm, +%RH:
10%
Added to the activation level to give alarm
level. Alarm level:
Actual MI
–
Safety Hysteresis Upper + Alarm=
= Actual MI
–
15% + 4% + 10 %
The principles are recognised from Fast RH regulation, but instead of a constant setpoint the
safety margin is determined against the mould index. When it comes to hysteresis and the
alarm, these work in the same way as for Fixed RH regulation.
As the reader will certainly have established, the relative humidity can be allowed to rise slightly
higher in the lower temperature range,with the support of the mould index, and thus provide an
energy saving. At higher temperatures, both the fixed and mould index regulation methods overlap
and thus the power consumption is the same.
