1. Product information
1.1 Function
Use The exodraft EBC30 is a true PID-based fan speed control used to maintain a constant pressure or
draft in a venting system. It can be used with RSV, RSIF, RSIB, IPVB, BESF, BESB and SFTA models to
control single phase, 120 V AC, motors directly and three-phase, 208-460 V AC, motors indirectly via a
VFD (variable frequency drive) that adjusts the motor speed.
The intended use of the control includes, but is not limited to controlling the:
• combustion air supply system
• draft in mechanical draft system serving individual or multiple heating appliance systems
• damper position in a modulating over-draft system to ensure proper draft is maintained in
individual or multiple heating appliance systems
• duct pressure in dryer venting systems
• duct pressure in ventilation systems.
The EBC30 can simultaneously control an exhaust fan, an intake fan or a draft damper. Any two of
these can be controlled simultaneously or they can be controlled individually.
Use of the control is not restricted to any type of fuel or type of heating appliance, dryer or venting
application.
The unit features “plug-and-play” to automatically monitor all terminals and register components
attached to the control during initial start-up. It comes pre-programmed from the factory, but can be
further programmed in the eld, if needed. The control will allow continuous or intermittent operation of a mechanical draft fan.
The control has an integrated safety system to assure the heating appliance will shut down in case of
fan failure or control failure. A unique priority operation function will probe the operating conditions
and allow as many appliances as possible to operate without fan assistance, provided the operation
is considered safe by the integrated safety system. The EBC30 has six(6) heating appliance interlock
circuits as standard but can be expanded in multiples of four(4) with the use of an additional relay
board or the ES12, relay control.
The control can be operated with a manual reset function (reset button) or an automatic reset
function. A self- diagnostic panel with LED’s monitors all connection terminals for easy service and
troubleshooting. The EBC30 can also operate in manual mode where the user sets the constant
speed. Provided the integrated safety system is satised, interlocked heating appliances are allowed
to operate. A bearing cycle activation function rotates the fan motor(s) once every 24 hours in case
the fan has not been operating during the previous 24 hour period.

Listings EBC30 is tested and listed to the Standard for Industrial Control Equipment, UL Standard 508 and CSA
C22.2 No. 14-10 as well as UL378, Standard for Draft Equipment.
1.2 Shipping

1.4 EBC30 control components
The EBC30 control is built up around a main board that controls all basic functions. In addition, a Triac board and a relay
board, are available for special functions. The main board controls draft/exhaust and air supply/ intake functions. It can
provide 0-10 V DC signals for Variable Frequency Drives (VFDs), an actuator or other devices accepting a 0-10 V DC control
signal. It also allows interlock of up to 6 appliances for control circuit voltages between 12 V AC and 240 V AC/12 V DC and
240 V DC, and has an integrated Proven Draft Switch (PDS) function. An external PDS is therefore not required.
The main board layout is shown below in g. 1:

Two add-on boards are available. A Triac board is available so the control can operate a 1 x 120 V fan or ventilator without
the need for an external drive. A Relay Board is available for applications with more than 6 appliances. The control can only
accept a single add-on board at a time. If there is a need for using the Triac board as well as the Relay board, install the Triac
in the EBC30 and use an ES12, Relay Box in lieu of the Relay Board.

3. Mechanical installation
3.1 Location
The control and the transducer must be installed inside, preferably in the mechanical room (boiler room).
The control does not need to be installed in an enclosure. Fig. 3 shows how the components are connected.
The transducer cannot be mounted inside an airtight enclosure.
It uses the boiler room pressure as reference pressure.
Fig. 3
3.2 Mounting of control
The control can be mounted directly on a wall or similar. The mounting holes are located inside the control as shown in
Fig. 4. The distance between the control and the transducer should not exceed three hundred (300) feet.
