Make up air equipment control

A system for controlling make-up air apparatus for a controlled building space comprising:

• a first sensor for sensing the operation of a first appliance within a building space, the appliance, when operational, acting to cause air to be exhausted from the controlled building space,
• a controller for the apparatus;
• a link for communicating a first signal with the controller that the first appliance is activated, the link acting to render the apparatus operational when the first appliance is activated;
• a device for determining the air flow requirements between the controlled building space and an environment outside of the controlled building space such as to ensure a predetermined balance of the pressure of air within the controlled building space and the environment outside of the controlled building space;
• means for opening a back-flow damper associated with the apparatus;
• and
• a power supply for activating a motor of the apparatus for a blower to draw air into the building space, the motor speed being determined in response to the predetermined air flow of operational appliances.

• communicating a first signal that the first appliance is activated thereby to render the apparatus operational when the first appliance is activated;
• determining the air flow requirements between the controlled building space and an environment outside of the controlled building space;
• opening a back-flow damper associated with the apparatus;
• monitoring the outside air temperature;
• activating a heater in the event that the outside air temperature is below a predetermined level;
• and
• activating a blower in the apparatus to draw air into the building space, the motor speed being determined in response to appliance operation.
