This CEC standard will go into effect July 1, 2014. Obtain the Certification List by emailing sales@pelicanwireless.com, or contact your local Pelican Sales Professional.

The requirements found in section 110.2 – Mandatory Requirements for Space-Conditioning Equipment in the CEC 2013 Building Energy Efficiency Standard, 2013 Title 24, Part 6, Subchapter 2, page 27, entails a Certification by Manufacturer of HVAC thermostats to meet 2013 California Title 24 standards:

110.2(b). Controls for heat pumps with supplementary electric resistance heaters.

Pelican Qualification:

  1. If the heat pump alone can maintain the heat load demand, supplementary heat will be left off.
    1. Pelican thermostats monitor room temperature rise, in real time, during a call for heat. If the heat pump cannot maintain at least a 5 ̊F temperature change per hour, it will use the supplementary heat. The thermostat makes the decision within 10 minutes of running the heat pump.

110.2(c). Thermostats.

The requirements found in section 120.2, Mandatory Requirements for Space-Conditioning Equipment of the CEC 2013 Building Energy Efficiency Standard, 2013 Title 24, Part 6, Subchapter 3, page 47 entails a Certification by Manufacturer of HVAC thermostats:

120.2(a). Thermostat controls for each zone.

Pelican Qualification: The supply of heating and cooling to each space-conditioned zone or dwelling unit can be and is usually controlled by an individual Pelican thermostat which responds to temperature within that zone and meets the applicable requirements of Section 120.2(b).

120.2(b). Criteria for zonal thermostatic control.

Pelican Qualification:

  1. When used to control comfort heating, the Pelican thermostat is capable of being set, locally or remotely, down to 55 ̊F or lower.
  2. When used to control comfort cooling, the Pelican thermostat is capable of being set, locally or remotely, up to 85 ̊F or higher.
  3. When used to control both comfort heating and comfort cooling, the Pelican thermostat provides a temperature range or dead band of at least 5 ̊F.

120.2(c). Hotel/motel guest room and high-rise residential dwelling unit thermostats.

Pelican Qualification:

  1. (A,B,C) Pelican guest room thermostats can provide numeric temperature set points in either   ̊F or  ̊C, have configurable set point stops accessible only to authorized personnel which can limit a 5 ̊F (3 ̊C) thermostat temperature adjustment by the guest.

120.2(d). Heat Pump Control.

Pelican Qualification:

  1. Heat Pumps that have supplementary electric resistance heaters are controlled using the Pelican thermostats be monitoring the change of temperature on a rate of 5 ̊F an hour*, to determine if the Heat Pump compressor can heat the space using its own heating capacity. If the change is less than this rate, the Pelican thermostat will use the supplementary electric resistance heater to meet demand. *(The Pelican thermostat makes this decision within 10 minutes of running the Heat Pump).

120.2(e). Shut-off and reset controls for space-conditioning systems.

Pelican Qualification:

  1. (A) During unoccupied hours, the Pelican thermostat can accept up to 12 setback schedules. Schedules can be set for every 4 hours or less, to allow for an individual to manually override the thermostat during unoccupied hours, and still have the thermostat automatically set back to a proper economy temperature setting.
  2. (A,B) Pelican’s thermostats automatically restart and operate the system to maintain both heating and cooling set points after power outage:
    1. When a Pelican thermostat is initially powered back on;

i.      If it is able to reach the Internet and receive current date/time, then it will automatically run the scheduled temperature inputs.

ii.      If it is NOT able to reach the Internet to receive current date/time, then it will automatically use the 2:00AM unoccupied temperature settings held within the thermostat.

  1. Multipurpose room less than 1,000 ft², classrooms greater than 750 ft² and conference, convention, auditorium and meeting center rooms great than 750 ft² can be equipped with a Pelican thermostat, that communicates over a wireless signal to a Pelican Proximity Sensor (PRX1), which is then wired to an Occupancy Sensor with a built-in dry contact relay output, to;

(A) Automatically increase the operating cooling temperature set point by 2 ̊F or more and set back the operating heating temperature set point by 2 ̊F or more.

  1. Any hotel and motel guest room with a Pelican Thermostat is able to be set up at least +5 ̊F (3 ̊C) in cooling mode and set down at least -5 ̊F (-3 ̊C) in heating mode no longer than 30 minutes after the guestroom has been vacated by using the Pelican Geofencing App which is able to automatically detect when a guest has left the hotel/motel.

120.2(h). Automatic demand shed controls (OCST Certified).

Pelican Qualification:

  1. Thermostat’s cool temperature can be remotely set up by four degrees or more in all noncritical zones using the Pelican Site Manager (EMCS).
  2. Thermostat’s heat temperature can be remotely set down by four degrees or more in all noncritical zones using the Pelican Site Manager (EMCS).
  3. Thermostats can be remotely reset to the temperatures in all noncritical zones to original operating levels using the Pelican Site Manager (EMCS).
  4. Thermostats can be programmed to provide an adjustable rate of change for the temperature setup and reset using the Pelican Site Manager (EMCS).
  5. (A) Thermostats can be locked-out or disabled by authorized facility operators; (B) Manual control by authorized facility operators allow adjustment of heating and cooling set points globally; and (C) Automatic demand shed control through the use of Open ADR 2.0 as OCST certified; through use of the Pelican Site Manager (EMCS).

Per the standard, All Occupant Controlled Smart Thermostats shall be self-certified by the manufacturer to the Energy Commission in accordance with Joint Appendix JA5 – Technical Specifications For Occupant Controlled Smart Thermostats (OCST) and Section 110.2(c)(b); approved above. See below the list of Title 24 OCST requirements that the Pelican thermostat meets or exceeds.

JA5.2 Pelican thermostats have onboard communication devices to receive Demand Response or price signals.

JA5.2.3 Pelican thermostats can receive and respond to a Demand Response Signal or price signal and enable the desired settings enrolled in by the occupant. Both basic system event modes can be overridden by the occupant through using the Pelican Site Manager (EMCS).

JA5.2.4 Pelican thermostats set and respond to event signals.

(a)    Automatic adjustment of the thermostat set point by either the default number of degrees or the number of degrees established by the occupant.

(b)   If a price signal indicates a price in excess of a price threshold established by the occupant, the thermostat will adjust the set point by either the default number of degrees or the number of degrees established by the occupant.

(c)    In response to either signal, the thermostat can be set to default to an event response that initiates set point offsets of +4 ̊F for cooling and -4 ̊F for heating relative to the current set points.

(d)   The thermostat allows occupants to modify the default event response with their own response for cooling and heating in response to either signal.

(e)   Occupants are able to change the event responses and the thermostat settings or set points at any time, including during an event.

(f)     A demand response event can be started either immediately or through the use of a specific start time as specified by the event signal.

(g)    A pricing event can be started either immediately or through the use of a specific start time as specified by the event signal.

(h)   The thermostat can have an occupant defined set point for cooling and heating in response to either event.

(i)      The thermostat automatically adjusts to the programmed schedule set points or the manually established set points after the end of the event.

JA5.2.5 A built in randomization delay algorithm takes effect at the end of an event to prevent all thermostats from ending the event at the same time. The end of the event can be seen using the Pelican Site Manager (EMCS).

JA5.3 Pelican uses the IEEE 802.15.4 wireless standard for network communication and is certified under the standard OpenADR 2.0.
