Safety instructions
Repairing components that fulfil a
safety function can compromise the
safe operation of the system.
For replacements, use only original
spare parts supplied or approved by
Viessmann.
Product information
To prevent condensate on the cooling
surfaces when cooling via a heating cir-
cuit, the contact humidistat detects the
relative humidity at the installation loca-
tion.
To prevent moisture damage, the con-
tact humidistat should respond in good
time before the dew point is exceeded.
The switching point to set for this
depends on the installation position of
the contact humidistat as well as on the
physical conditions, e.g. installation in a
cool or warm cellar.
(cont.)
Install the components with new gas-
kets.
As soon as the switching point is
exceeded, the cooling function is inter-
rupted. A message is shown on the
control unit.
