CASE 3:
•
If you connect the “PARENT” connector of the “CHILD-
1” unit to the “1” connector of the “CHILD-2” unit, the
“CHILD-2” unit will operate as an individual unit, and will
not be part of the Easy-Link System .

WARNING
Connecting two
“PARENT”
connectors
together from two separate units
may
damage the computer board
. The
communication cable has a female end
and a male end so it’s impossible to have
a PARENT-to-PARENT connection with the
communication cable . Do not splice or
modify connectors .
CASE 4:
•
If a remote controller is used, it has to be connected to
the “PARENT” unit . If the remote controller is connected
to a “CHILD” unit, it will only control that particular
individual “CHILD” unit and will not control the Easy-Link
System as a whole .

APPLICATIONS
Space-Heating Applications
WARNING
•
In order to purge air in water pipes
within a closed-loop system, an air vent
and air separator should be installed
in the system. Required circulation
flow rates are labeled next to each
application diagram. These flow rate
requirements must be followed
.
•
Toxic chemicals used in boiler treatments
such as alcohol, glycerol and glycol
groups must not be introduced into the
system if the system incorporates an
open-loop potable water system .
•
The water heater can be used to supply
potable water and space heating and shall
not be connected to any heating system or
component(s) previously used with non-
potable water where any chemicals were
added to the water heating appliances .
•
Water heaters for combination water/
space heating cannot be used in space
heating applications only .
•
When the system requires water for
space heating at temperatures higher
than required for other uses, a means
such as a mixing valve shall be installed
to temper the water for those other uses
in order to reduce scald hazard potential .
•
Water temperature over 52 °C (125 °F)
can cause severe burns instantly or death
from scalding .
