“Unit # Low Temp Alarm”
The water temperature inside one or more tank type
water heaters has fallen below the Low Temp Alarm
set point established on the iCOMM web site. The #
symbol in the error message is replaced with the
effected appliance’s network address on the
iCOMM™ network.
Possible Causes:
• Sensed water temperature is below the Low Temp
Alarm set point established on the iCOMM™ web
site.
• The water heating appliance(s) is not operating at
full capacity and requires service.
• The water heating appliance(s) is undersized and
cannot meet demand.
Service Note:

silence the alarm if it is sounding - see Figure 2 on
page 6 and Display Button Operation on page 30.

View the current Low Temp Alarm set point and
the Low Temp Delay time delay setting for the
water heating appliance with the same iCOMM™
network address as shown in the error message
on the CM’s LCD. These settings are shown in the
Setup tab for an appliance online.
Consider lowering the Low Temp Alarm set point
or increasing the Low Temp Delay time delay set-
ting if the hot water demand is being met and this
alarm condition is not warranted.
The Low Temp Delay time delay setting: the time
the alarm condition must remain active before the
iCOMM™ web application will activate a low tem-
perature alarm condition at the CM.
• If the hot water demand is not being met have a
qualified service technician verify the water heat-
ing appliance(s) is operating at full capacity.
• If the water heating appliance(s) is operating at
full capacity additional or higher capacity water
heating appliances will be required to meet the
demand.
• If all the above steps have been performed and
the problem has not been corrected - call 888
928-3702 for further technical assistance.
