Chapter 16: Alarms
• Case #1: If more water was consumed in the last 24 hours than in the 24 hours that precede, the
controller will determine how much more water was 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.
• Case #2: If less water was consumed in the last 24 hours than in the 24 hours that precede, the con-
troller will determine how much less water was 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.
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). On initial
controller startup: the 48 hour countdown starts when the water meter is enabled. At the beginning of a
group: the 48 hour countdown starts at the startup of a new group. After a water consumption alarm, the
48 hour countdown starts after having acknowledged a high or low consumption alarm.
Setting the Alarm Start and Stop Temperatures
1. Using the menu select arrow keys, navigate to Start / Stop Temps→Alarms .
2. Set the following parameters:
Clean mode Set the temperature below which a temperature alarm sets off during the clean
mode.
Low/High Alarm Set the room temperature below and above which a temperature alarm sets off.
Critical temperature
alarm Specify what is the absolute maximum temperature allowed in the house (ranges
from 0.5 above the house set point to 120ºF (48.9°C)). *Accessible if the outside
temp. sensor is enabled
Water 1 spill limit Specify the maximum amount of water that can be consumed in a 15-minute delay.
This parameter ranges from 1 to 10,000 liters(1 to 2, 641 gallons)/15 min . *This
parameter is accessible if the water meter is enabled.
Water 1 high 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 the water meter is enabled.
Water 1 low 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 the water meter is enabled.
Disable low/high
water 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 before it can start monitoring the high/low water con-
sumption 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 alarm
units *Accessible if a SP probe is enabled
