Abstract
An HVAC controller, such as a thermostat, is configured to receive and accept one or more requests for a temporary boost in ventilation. The requests may be received from one or more remotely located ventilation boost control units located throughout the building, and/or through a user interface of the HVAC controller itself. In some cases, the HVAC controller may be configured to coordinate multiple requests for ventilation, and adjust the ventilation time as appropriate.
Claims23
A thermostat configured to control one or more components of an HVAC system of a building including a ventilation unit having a ventilation controller, the thermostat comprising:
- a temperature sensor;
- a user interface including a display;
- a memory;
- and
- an I/O block for sending and/or receiving signals to and/or from the one or more components of the HVAC system, including one or more wireless ventilation boost control units;
- and
- a controller coupled to the temperature sensor, the user interface, the memory, and the I/O block, the controller configured to read a temperature value via the temperature sensor and to control one or more components of an HVAC system in order to maintain a desired temperature set point in the building, the controller further configured to wirelessly receive a signal indicative of a request for ventilation for a predetermined amount of time from the one or more wireless ventilation boost control units and, in response, to send one or more commands to the ventilation controller of the ventilation unit in order to ventilate the building for a ventilation time, wherein the ventilation time is based, at least in part, on the predetermined amount of time.
An HVAC controller configured to control one or more components of an HVAC system of a building including a ventilation unit having a ventilation controller, the HVAC controller comprising:
- an I/O block for sending and/or receiving signals to and/or from the one or more components of the HVAC system, including one or more wireless ventilation boost control units;
- and
- a controller coupled to the I/O block, the controller configured to wirelessly receive a signal indicative of a request for ventilation for a predetermined amount of time from the one or more wireless ventilation boost control units and, in response, to send one or more commands to the ventilation controller of the ventilation unit in order to ventilate the building for a ventilation time, wherein the ventilation time is based, at least in part, on the predetermined amount of time.
A method of increasing ventilation in a building comprising:
- receiving a first request at a thermostat for ventilation for a first predetermined amount of time;
- commanding a ventilation unit to ventilate for the first predetermined amount of time in response to the first request;
- receiving at the thermostat a second request for ventilation for a second predetermined amount of time, the second request received at the thermostat later than the first request;
- and
- comparing a remaining time of the first predetermined amount of time to the second predetermined amount of time to determine if, in response to the second request for ventilation, the remaining time of the first predetermined amount of time should be extended.
