Future energy Codes

This is part of a new energy / building code that is currently being worked on in California. The key here is that the "utility" will be able to override "your" temperature setting when they "need" to during an "emergency".

This is the link to the complete new code.

http://www.energy.ca.gov/2007publications/CEC-400-2007-017/CEC-400-2007-017-45DAY.PDF

The below is from page 63-64 of the proposed code.

SECTION 112 – MANDATORY REQUIREMENTS FOR SPACE-CONDITIONING EQUIPMENT
_

A. Price Events. The PCT shall be shipped with default price-event offsets of +4°F for cooling and -4°F for heating enabled; however, customers shall be able to change the offsets and thermostat settings at any time during price events. Upon receiving a price-event signal, the PCT shall adjust the thermostat setpoint by the number of degrees indicated in the offset for the duration specified in the signal of the price event. The PCT shall also be equipped with the capability to allow customers to define setpoints for heating and cooling in response to price signals as an alternative to temperature-offsetting response, as described in Reference Joint
Appendix JA5._
_

B. Emergency Events. Upon receiving an emergency signal, the PCT shall respond to commands contained in the emergency signal, including changing the setpoint by any number of degrees or to a specific temperature setpoint. The PCT shall not allow customer changes to thermostat settings during emergency events.

_3. Other Required Capabilities. PCTs shall also have the following capabilities. Technical detail of items A though E below shall be included in Reference Joint Appendix JA5: A. Include at least one industry standard expansion/communication port. Insertion of a utility-specific
communications module shall disable the default statewide communications hardware built in to the PCT unless the utility module is removed or is no longer receiving a signal. B. Provide user information regarding communications system connection status, type of event (price or emergency), and other maintenance-related information. This information shall be on the standard PCT display,
using a Liquid Crystal Display, standalone indicator using Light Emitting Diodes, or other means. C. At a minimum, standardize terminal mapping of terminal numbers 1-9. This approach must include 24 volt power supply, both analog and digital PCTs, and must support heat pumps with resistance heat strips and
reversing valve in both residential and small commercial packaged units.
_

D. Include the capability to randomize, over a 30-minute period after the end of an event, the time at which the thermostat returns to the programmed setpoint.
