NOTE 4: Overrides (Optional, Power Company
Permitting) / Multiple Control Strategies
With the addition of the 3-zone override module to the
CCRP, peak override of 6 of the 9 circuits is possible. If
enabled, relays 1, 2, 3, 7, 8, or 9 can be used in 60-minute
intervals during a peak control period, if desired. Devices
controlled by relays 4, 5, and 6 can never be overridden.
Installation instructions for this feature are provided with
the override module. (Order item #1302060.)
For power companies desiring to control loads separately using multiple signals, the override ports in the termi-
nal block can also be used to recognize these signals and trigger the peak control.
OV1 = allows relay 1 circuit to be overridden or controlled on a separate rate/control strategy
OV2 = allows relay 2 circuit to be overridden or controlled on a separate rate/control strategy
OV3 = allows relay 3 circuit to be overridden or controlled on a separate rate/control strategy
OV4 = allows relay circuits 7, 8, and 9 to be overridden (cannot override these circuits separately) or
controlled on a separate rate/control strategy
* The 4-pole CCRP is configured to utilize relays 1, 2, 3, and 7.
NOTE 5: Room Temperature Set Back or Independent Relay Input
If using the CCRP with the 1000, 2000 and/or 2100 series room heating units and utilizing the automatic room
temperature set back feature, the addition of a signaling device is required to initiate the set back time. This
signaling device attaches to the “E” and "R" positions of the terminal strip in the CCRP. The transmitter in the
CCRP receives the set back signal, and, in turn, sends the signal (wireless) to the heater(s).
If the power company uses multiple signals for peak control of devices on different rate strategies, the “E”
terminal position can be used as the input port to trigger peak control of those devices on the separate strategy
rather than for room temperature set back.
NOTE 6: Jumpers 8 and 9 (Isolated Relay Switching - Multiple Control Strategy Applications)
These jumpers couple the relays to different input signals and enable separate control of the circuits connected
to them. If these jumpers are set to the “ON” position, the relays are controlled by the microprocessor on the
circuit board through either the “P” or “E” input terminals depending on dip switch 6 setting in the CCRP. If
Jumper 8 (J8) is in the “OFF” position, relays 7, 8, and 9 respond only to the OV4 input terminal. If Jumper 9
(J9) is in the “OFF” position, relay 1 responds only to the OV1 input terminal; relay 2 responds only to the OV2
input terminal; and relay 3 responds only to the OV3 input terminal.
Depending upon how the controllable devices are field wired into the circuit board, the positions of J8 and J9
jumpers, and dip switch 6 setting, it is possible to have the CCRP provide individual load control for up to 6
separate control strategies. If utilizing multiple control strategies, refer to Dip Switch Settings description, the
Relay Triggering Schematic, and the Example System Wiring Diagram for Multiple Strategies in this manual.
NOTE 7: Anticipated Peak
Typically, power companies are capable of sending one signal for peak control of selected devices. There are
some instances; however, where power companies are capable of sending multiple signals for control pur-
poses. In these situations, it is possible to have on-peak hours, off-peak hours, and anticipated peak (pre-peak)
hours.
On-peak hours are those times during which a controllable load is disabled. Off-peak hours are those times
during which a controllable load is allowed to operate. Anticipated (pre-peak) hours are those times during
which ETS equipment can be prepared for an upcoming on-peak (control) period, or a time when power
companies can apply customized control of the ETS equipment. If uncertain as to whether this option is being
used in your area, contact your local power company representative.
Š Devices controlled by relays 4, 5, and 6 can never
be overridden.
Š If the CCRP is being used to do both peak control
and automatic charge control of fluid regulated
ETS room heating systems, then peak override of
the fluid regulated ETS heater(s) is not possible.
