MANAGEMENT OF OTHERS
Some auxiliary adjustments are envisaged, briefly described in the following sections.
9.1
Compensation for setpoint
For summer mode only (parameter
MOdE=0=CooL
), the cooling adjustment requests compensation of the room regulation setpoint according to the external tempera-
ture (parameter
P
C01
enables summer setpoint compensation).
This function is important for avoiding excessive changes of temperature between the outside and indoor environments to ensure comfort in the different conditions
.It is also very important for enabling the system to save energy.
The compensation setpoint increases in proportion to the increase in the external temperature until it reaches the maximum admissible threshold set by the parameter
PC02
(Maximum setpoint for summer compensation)
.
The external temperature probe must be enabled to use this function. If the external probe is in error mode, this function is inhibited.
9.2
Last date of maintenance
In the Menu
Maintenance Operator->Operation
you will find a page with the ability to memorize the last date of maintenance for the plant. By pressing “Update”, the
old date which is in the system will automatically be updated with the new correct date; updating the maintenance date can be done at parameter
PM90
.
9.3
Automatic daylight saving time
The program can manage the automatic switch-over from daylight saving time to standard time. The parameter
PH25 Enable automatic standard time
allows you to
control the enabling and the choice of the zone between Europe and North America.
By enabling the Europe zone function at 1 am on the last Sunday of March, the clock will be moved one hour ahead while at 1 am on the last Sunday in October, it will
be moved one hour back.
By enabling the N. America zone function at 2 am on the second Sunday of March, the clock will be moved one hour ahead while at 2 am on the first Sunday in No-
vember, it will be moved one hour back.
