The system and approach may be a room controller built on top of a Niagara™ framework or launched from a Niagara workbench, and leverages extensible of Niagara. The system and approach may be web-based and used to test and verify the room condition per preset conditions. The system may have steps or tabs. They may incorporate screens for a create/open task, select test zone, read flow, hood/booster, T-stat set-up or temperature lever set-up, visual checks, and a report. One may create a new task and edit any existing task on the controller. One may move from task to task in either direction or go directly to the report of a completed task. ## Claims ### Claim 1 A system for verification of conditions of a space, comprising: a controller; a flowing mechanism coupled to the controller; a heating mechanism in the space, connected to the controller; and a cooling mechanism in the space, connected to the controller; and wherein: the space is controlled by the controller via the flowing mechanism, the heating mechanism or the cooling mechanism, as selected, in a full heating condition, a full cooling condition, or a full flowing condition, respectively, to achieve one or more preset conditions; and current conditions of the space are verified by the controller to meet the one or more preset conditions after a wait period to allow the selected full heating condition, a full cooling condition, or a full flowing condition to take effect. ### Claim 2 (depends on 1) The system of claim 1, further comprising one or more thermostats connected to the controller. ### Claim 3 (depends on 1) The system of claim 1, further comprising one or more flow measuring devices configured to measure flow values in the space. ### Claim 4 (depends on 1) The system of claim 1, wherein the flowing mechanism includes a valve. ### Claim 5 (depends on 1) The system of claim 1, wherein the space is a clean room. ### Claim 6 (depends on 1) The system of claim 1, wherein a report of the current conditions is generated by the controller. ### Claim 7 (depends on 1) The system of claim 1, wherein the controller includes a user interface, and wherein the user interface includes a display and a control mechanism. ### Claim 8 (depends on 7) The system of claim 7, wherein the display can show a screen selected from a group comprising a create/open task screen, a select test zone screen, a read flow screen, a hood/booster screen, a thermostat set up screen, a visual checks screen and a report screen. ### Claim 9 (depends on 8) The system of claim 8, wherein the read flow screen shows one or more conditions of the space that can be read in terms of occupancy, unoccupancy, temperatures and flow values. ### Claim 10 (depends on 9) The system of claim 9, wherein the one or more conditions are selected from a group comprising cooling demand, heating demand, occupancy vent demand, unoccupancy vent demand, hood demand and booster demand. ### Claim 11 A system for verification of conditions of a clean room, comprising: a controller; a valve coupled to the controller; a heating mechanism in the clean room, connected to the controller; a cooling mechanism in the clean room, connected to the controller; and one or more sensors connected to the controller, wherein the one or more sensors are configured to measure current conditions in the clean room; and wherein: current conditions of the clean room are verified by the controller to meet preset conditions; the clean room is controlled by the controller via the valve, the heating mechanism or the cooling mechanism, in a full heating condition, a full cooling condition, or a full flowing condition, respectively, to achieve the preset conditions in response to a user input; and the current conditions are verified to match the preset conditions by the controller. ### Claim 12 (depends on 11) The system of claim 11, further comprising one or more thermostats connected to the controller. ### Claim 13 (depends on 11) The system of claim 11, wherein a report of the current conditions is generated by the controller. ### Claim 14 (depends on 11) The system of claim 11, wherein the controller includes a user interface, and wherein the user interface includes a display and a control mechanism. ### Claim 15 (depends on 14) The system of claim 14, wherein the display can show a screen selected from a group comprising a create/open task screen, a select test zone screen, a read flow screen, a hood/booster screen, a thermostat set up screen, a visual checks screen and a report screen. ### Claim 16 (depends on 15) The system of claim 15, wherein the read flow screen shows one or more conditions of the space that can be read in terms of occupancy, unoccupancy, temperatures and flow values. ### Claim 17 (depends on 16) The system of claim 16, wherein the one or more conditions are selected from a group comprising cooling demand, heating demand, occupancy vent demand, unoccupancy vent demand, hood demand and booster demand. ### Claim 18 A method for verification of conditions of a clean room, the method comprising: determining current conditions of the clean room; determining preset conditions for the clean room; receiving a user input to select a full heating condition, a full cooling condition, or a full flowing condition to achieve the preset conditions; controlling the current conditions to match the preset conditions; and verifying that the current conditions match the preset conditions within a specified percentage. ### Claim 19 (depends on 18) The method of claim 18, wherein the current conditions of the clean room are controlled via a controller, and wherein the controller controls the air flow control mechanism, the heating mechanism or the cooling mechanism, as selected, in a full heating condition, a full cooling condition, or a full flowing condition, respectively, to achieve the preset conditions. ### Claim 20 (depends on 19) The method of claim 19, wherein the controller comprises a user interface and the user interface comprises a display and a control mechanism, and wherein the display can show a screen selected from a group comprising a create/open task screen, a select test zone screen, a read flow screen, a hood/booster screen, a thermostat set up screen, a visual checks screen, and a report screen.
