Series 35-9X Modulating
Platform Ignition Module (PIM
®
)
OPERATION AND INSTALLATION INSTRUCTIONS
DESCRIPTION
The Fenwal Controls Platform Ignition Module (PIM
®
) integrates
the functions of Automatic Ignition Control with temperature
regulating and control functions. The PIM is designed for a range
of hydronic boilers including both staged systems and
modulating types. The PIM can be configured as a direct spark
ignition (DSI), intermittent pilot (IP) or Hot Surface Ignition
(HSI) to provide safe lighting and supervision of the burners in
an appliance. The PIM is also designed to connect to and receive
commands from the tekmar
®1
Host Controller. When connected
to a Host Controller, the PIM offers expanded control
functionality including Domestic Hot Water, outdoor reset,
diagnostic messages, and other system capabilities.
APPLICATIONS
The PIM and Host Controller system is suited to a wide variety
of gas-fired hydronic heating systems including:
•
High-efficiency Modulating Condensing Boilers
•
Fan-assisted single and multi-staged Boilers
•
Multiple Boiler Installations using intelligent sequencing
•
Intermittent Pilot based Hydronic appliances
•
Water Heaters
•
Pool and Spa Heaters
