I.8.7 SETTING SUMMER AND WINTER SET-
POINTS
IMPORTANT!
When modifying or varying the machine's operating
parameters, make sure that you do not create
situations that conflict with the other set
parameters.
The user is authorised to adjust the summer and winter set-point values
within the adjustment limits indicated in Par. I.8.6.
If, for example, the Coo (summer set-point) parameter is set at 0, the
A05 parameter (antifreeze alarm set-point) must be adjusted in order to
prevent the machine from shutting down. The A05 parameter is
password protected, therefore it can only be modified by authorised
RHOSS
S.p.A. personnel.
Whenever the A05 parameter is assigned a value below 3°C it is
essential to use water mixed with a suitable percentage of ethylene
glycol.
To set the summer and winter set-points, proceed as follows:
Press the Prg key for 2 seconds to gain access.
By pressing the MODE key, it is possible to move onto the label that
makes it possible to set the winter set-point.
