BOILER CONTROLLER
Read above to verify if you need boiler control enabled. DO NOT enabled
boiler control if the Z8 is only being used to open a hot water valve. Boiler
control should only be active if the Z8 is maintaining the boiler’s hot water
supply temperature.
Operating Range
Set the temperature range that the Z8 should detect/maintain during
a heating cycle. The Z8 will enabled and disable its (W2) output to
maintain this temperature range. Settable from -20°F to 180°F.
INPUT SENSOR T1, T2, T3
Each input has a default use, but can be configured for
the function it is wired to detect.

ALARM ACTIVE INDICATION
If set to [Closed] a notification will be
generated on detection of the
dry-contact relay closing. If set to
[Open] a notification will be generated
on detection of a dry-contact relay
opening.
ALARM
Set to Alarm if a dry-contact output relay is
connected to the terminal and you want to
get an alarm if the contact changes to a
specific position.
BOILER TEMPERATURE
This setting is only available if Boiler Control is set to On.
Setting an input to Boiler Temperature automatically
correlates this temperature reading to being the Boiler’s
Supply Water Temperature. The Z8 will use this
temperature reading to maintain the boiler supply water
temperature during a heating cycle. Temperature will be
maintained based on the target Operating Range set under
the Boiler Control configuration.
TEMP MONITOR
This setting turns the input
into a stand alone
temperature input and will not
affect the functions of the Z8.

BOILER CONFIGURATION OPTIONS
By enabling boiler control you are instructing the Z8 to use (W2) as a boiler enable output. With this feature active, the Z8 will NOT energize (W) until
it detects the boiler’s supply water temperature to be within a specified range. This feature requires the Z8 to be able to read the boiler’s hot water
supply temperature. Reference the boiler installation guide on page 27 of this document and contact Pelican Technical Support for further assistance.
