Each Coris Gateway module can support up to 35 ICTs. Once your Gateway is connected to a router with an Ethernet cable, it automatically connects to Coris' secure servers in the cloud. The ICTs are then able to communicate with the servers.
Whether you have rooftop air conditioners or package units, your existing thermostats can be replaced with Coris Internet-Controlled Thermostats (ICTs).
Once installed, Coris' encrypted wireless mesh network enables ICTs to communicate with one another to reach a Gateway module.
A large restaurant with banquet areas installed Coris thermostats to control the large air conditioning units in the restaurant. Since most DR events were scheduled from 1pm to 5pm, the restaurant pre-chilled the dining areas on the mornings of an event (they were notified the night before of an upcoming event); they use the Coris controls to turn the A/C units off at 1pm, but keep fans running. Lunch usually lasts until 2pm, so the dining areas remain comfortable. With the A/C turned back on at 5pm, the dining areas were comfortable for dinner.
A golf course installed Coris thermostats and Coris water pump controls to participate in DR events. Similar to the restaurant mentioned at left, the dining and active member areas are pre-chilled before DR events, but the bar area is left alone because it includes an informal dining area and is occupied most afternoons. The large pumps that move water between ponds (reservoirs for sprinkler systems) are turned off during DR events.
The owner of a 450K-square-foot office building wanted to participate in the local utility’s demand response program. Their electrical usage usually peaked at 1,500KW during warm summer days. The demand response aggregator worked with the owner to determine the amount of load that could be shed without causing discomfort for tenants or operational problems. A goal of 500KW to be shed during DR events was agreed upon, and Coris HVAC controls were installed to manage the load shedding. During the testing and validation, Coris provided support to the building owner’s staff, and they were able to exceed the goal. They have successfully exceeded their goals for all DR events since installation.
Yes, there is no limit to the number of facilities or locations that can be controlled through Coris' web-based control interface.
Yes, the thermostats can be "locked out" during DR events—prohibiting manual adjustments to individual thermostats.
Yes, many buildings pre-chill 4° to 6° below the normal target temperature before the event starts; by pre-chilling, tenant space is still comfortable by the end of the event. This can also be done with a single click using the Coris system.
