parameters and a history of detected faults are stored in  
rewritable memory in the microcontrollers. A loss of power  
does not affect either of the memories.  
Gas Valve (MCB - 24VAC - required): Provides power to activate  
the gas valve. The gas valve cannot be activated when the ECO  
contacts are open.  
Low Water Cut Off (MCB - 24VAC - optional): Directly connected to  
Temperature probes (MCB - outlet and either inlet or tank are  
required): The MCB accepts analog temperature inputs from  
up to three sensors (inlet, outlet, and remote).  
A green LED is mounted on the PDB to indicate when line voltage  
is applied (the PDB also contains a yellow and red LED, and a  
test/run jumper that are used during installation to verify proper  
power connections). A red LED on the MCB is used to indicate  
when the 24VAC input fuse has blown.  
ECO input (MCB - required): The ECO (energy cut off) is a hi-  
limit switch located inside the outlet probe. It is a normally  
closed switch that opens if the probe is exposed to a  
temperature higher than the trip point. Once tripped, the control  
system needs to be manually reset.  
Yellow LEDs are located near the microcontrollers on the MCB.  
Thermostat input (MCB - optional): This input is set up to work with  
an externally connected thermostat that provides a contact closure. These LEDs are “heartbeat indicators,” and blink approximately  
If this input is closed and everything else is in the proper state, a “call twice per second to indicate that the microcontrollers are running.  
for heat” condition will be initiated. These leads should be shorted  
together when a thermostat is not being used. If it is desired that the  
of the system should be set higher than the temperature that the  
thermostat is controlling. This will allow the thermostat to control the  
boiler. When the thermostat closes, a call for heat will be generated  
until the thermostat determines that the required temperature has  
been reached.  
The MCB has two jumpers. JP1 on the MCB is used to terminate  
the external communications line. It is normally left off and installed  
when the external cable is very long.  
The EMC modulation system operates with Silicon Carbide Igniters.  
Blocked Flue (MCB - required): Normally closed switch that opens  
if the flue becomes blocked during operation.  
Blower Prover (MCB - required): Normally open switch that closes  
when the air pressure produced by the blower is above the set point.  
The EMC modulation controller has four modes of operation:  
Initialization, Standby, Running/Modulation, and Service. The  
internal MCB micros control these modes through a sequence of  
Procedures" section.  
Low Gas (MCB - required): Normally closed switch that opens  
when the gas pressure falls below the trip level. This input is  
enabled/disabled by a dip switch on the MCB  
When power is applied to the system, it enters the initialization  
mode and the following automatic functions are performed:  
Hi Gas (MCB - required): Normally closed switch that opens if the  
gas pressure exceeds a set value. This input is enabled/disabled  
by a dip switch on the MCB.

Low Water Cut Off (MCB - optional): Normally open switch that  
closes when water reaches preset level. This input is enabled/  
disabled by a dip switch on the MCB.  
Stored values are recalled from memory.  
Configuration dipswitches are read.

Flow (MCB - required): Normally open switch that closes when  
flow exceeds a set value.

Flame (MCB - required): Returns a signal to the microprocessor if  
flame is detected on the burner. If the flame rod is missing or  
shorted, the flame will not be detected.  
After initialization is complete (approximately 10 seconds) the  
system turns the green LED off and goes to the standby mode  
(yellow "Standby" LED on), unless a previously stored fault  
has been recalled, which will send the system into the service  
model (red "Service" LED on). In standby mode the display  
shows the temperature screen and in fault mode the current  
error screen is displayed.
