The IQ Boiler Control stores two boiler supply 

temperature setpoints in its memory; one setpoint 

is for the High Limit Setting and the second is for 

the Operating Setpoint. 

IQ Control System overview 
The “IQ Control System” consists of an IQ Boiler 

Control and an IQ Option Panel with optional “plug 

in” cards:  

•   Fully integrates both factory and field 

installed components, simplifying installation 

and troubleshooting.  

•  Efficiently operates the entire boiler system 

to save energy.

The heart of Burnham’s IQ Control System is the 

IQ Boiler Control.  The IQ Boiler Control replaces 

the traditional separate ignition control, primary 

boiler aquastat, as well as the fan and circulator 

relays. 

The IQ Option Panel works together with the IQ 

Boiler Control to provide an easy and convenient 

means to “plug-in” additional functionality to a 

boiler system.

The IQ Option Panel is a standard component 

provided along with the IQ Boiler Control.  The 

IQ Option Panel functions as a “motherboard” 

to accept up to three (3) IQ Option Cards and 

provides the necessary mechanical connections 

(with no screws required), along with the power 

and interconnection wiring into the IQ Boiler 

System.  Only wiring from field-installed sensors 

is required.  The IQ Option Panel includes a 

dedicated digital readout that provides option card 

status information, diagnostics and setup functions 

when necessary.

•  Ensures adequate heat and supply of 

domestic hot water. 

•  UL / CSA Listed or Recognized and tested 

as part of a complete system.

•

Communicate with other EnviraCom

™ 

enabled components to provide a complete 

system solution to maximize comfort and 

energy efficiency.

When the optional Outdoor Air Reset Card is 

installed in the IQ Option Panel, the Operating 

Setpoint temperature is automatically adjusted 

according to the outdoor temperature.  For 

example, as the outdoor temperature increases 

the Operating Setpoint temperature is reduced 

from the High Limit Setting to save energy 

while improving home comfort.  By better 

matching boiler heat supply to actual home 

heat demand, room air temperatures are more 

closely maintained.  In addition, when there is 

a domestic hot water (DWH) heat request, the 

Operating Setpoint temperature is automatically 

adjusted to a DHW Setpoint to satisfy the DWH 

heating requirements.  When the Outdoor 

Air Reset Card is not installed the Operating 

Setpoint equals High Limit Setting.
