Set the following parameters:2.
(Refer to the previous section to get further informa-
tion on these parameters)
• Temperature Alarms
Clean mode — Set the temperature below
which a temperature alarm is set off in clean
mode.
Lo/Hi alarm — Set the room temperature
below and above which a temperature alarm
is set off.
Critical temperature — Set the absolute
temperature above which an alarm is set
off. *Accessible if an outside temperature probe is
enabled (section 4.7.1).
• Water Consumption Alarms
Water 1-2 spill limit — Specify the maximum
amount of water that can be consumed by
each wate r meter per 15 mi nutes. This param-
eter ranges from 1 to 10,000 liters/15 min).
*This parameter is accessible if a water meter is
enabled (sec. 4.7.1)
Water 1-2 Hi Alarm Usage— An alarm is set
off if the water consumption measured by a
water meter in the last 24 hours is too high
compared to the consumption measured
in the 24 hours that precede. Set the high
alarm limit of each water meter separately.
To disable this monitoring function, decrease
the parameter value until the word “Off ”
is displayed. *This parameter is accessible if
a water meter is enabled (sec. 4.7.1). Refer to the
previous section to get more information about this
alarm limit.
Water 1-2 Lo Alarm Usage — An alarm is
set off if the water consumption measured
by a water meter in the last 24 hours is too
low compared to the consumption measured
in the 24 hours that precede. Set the low
alarm limit of each water meter separately.
To disable this monitoring function, decrease
the parameter value until the word “Off ” is
displayed. *This parameter is accessible if a water
meter is enabled (sec. 4.7.1). Refer to the previous
section to get more information about this alarm
limit.
Reset Alarm ? — If a high or low water
consumption alarm is on, select “Yes” to
acknowledge the alarm condition. Note that
when a reset is made, the controller needs
48 hours to gather new consumption data be-
fore it can start monitoring the high/low water
consumption alarms again (no consumption
alarms can happen by the end of this 48-hour
delay). *This parameter is accessible if a high or a
low water consumption alarm is on.
• Static Pressure Alarms
*Accessible if a SP probe is enabled (section 4.7.1).
Low / High alarm — Set the pressure
levels below and above which an alarm
is set off.
Delay — The high or low pressure condi -
tion must be maintained on this period
of time before the controller sets off the
alarm. Set the static pressure alarm de-
lay to the desired value (in seconds).
Water Spill Alarm: A water spill alarm sets
off when the consumption of a water meter
exceeds its respective consumption limit.
This limit can be adjusted from 0 to 10,000
gallons or liters per 15 minutes.
Water Consumption Alarms: When
the percent difference in water consumption
between the last 24-hour period and the pre-
vious 24-hour period is greater than a given
maximum value, an alarm is set off. This veri -
fication applies to each individual meter.

Water Consumption
The high and low water consumption alarm
limits are defined as follows:
• Case #1: If more water has been consumed
in the last 24 hours than in the 24 hours that
precede, the controller will determine how
much more water has been consumed and will
convert this value in percent. If the surplus
(in %) is higher than the “High Alarm” limit,
the controller will set off an alarm.
Last 24h - Previous 24h x 100 > Hi Alarm
Previous 24h
• Case #2: If less water has been consumed
in the last 24 hours than in the 24 hours that
precede, the controller will determine how
much less water has been consumed and will
convert this value in percent. If the deficit (in
%) is higher than the “Low Alarm” limit, the
controller will set off an alarm.
Previous 24h - Last 24h x 100 > Lo Alarm

Before it can start monitoring the water
consumption alarms, the controller needs
to gather consumption data for 48 hours
in a row (no consumption alarm can be
detected within this 48-hour delay):
a) O n i n it i al c on t ro l le r st a tu p : t h e
48-hour countdown starts when the water
meter is enabled;
b) At the beginning of a group: the 48-hour
countdown starts from the moment the new
group starts;
c) After a water consumption alarm: the 48-hour
countdown starts after having acknowledged
a high or low consumption alarm.
