Outside Air Damper with Electric Actuator (0…10V DC or
4…20 mA)
The existing outside air damper has an electric actuator with a
0…10V DC or 4…20 mA control signal:
i. Remove the (+) control wire from the actuator (+) terminal and
connect it to terminal 155 on TB2 in the FanMaster enclosure.
ii. Wire terminal 153 on TB2 to the actuator (+) terminal.
iii. Test the system and make sure that operation does not cause an
alarm in the existing system which may cause an HVAC
shutdown due to opening the 4…20 mA loop or other failure to
follow command alarm.
Outside Air Damper with Pneumatic Actuator
The existing outside air damper has a pneumatic actuator with a mA
to Pressure controller (I to P):
i. Either remove the (+) control wire from the I to P and connect
through the relay as in steps “i. a.” and “i.b.” above, or obtain an
electrically actuated pressure valve which expels the pneumatic
actuator control air when the valve is actuated. Use the
FanMaster damper relay to switch power for the pressure valve
(separately sourced AC or DC power is required).
Outside Air Damper with Electric Actuator (0…135 Ohm)
The existing outside air damper has an electric actuator with a
0…135 ohm control signal:
i. Remove the (+) power supply wire from the actuator and
connect it to terminal 155 on TB2 in the FanMaster enclosure.
ii. Wire terminal 153 on TB2 to the actuator (+) power supply
terminal.
Important: The installer must determine and ensure the proper
operation of this contact when used to force the damper
closed.
