IntelliPEAK DirectLink can be installed to control the following loads.

Description

HVAC

Yes

Water Heater

Yes

Pool Pump

Yes

Refrigeration

Yes

It requires connection to line power and must be installed by a trained and experienced
technician. Do not under any circumstances open the door and touch any components

inside, as line voltage (120 – 240 VAC) is present. You could damage this product or cause
a hazardous condition if you fail to follow these instructions.

HVAC

For HVAC, IntelliPEAK DirectLink is typically installed outside, near your compressor. It is
wired to the same power source as the compressor and relays inside IntelliPEAK will
intelligently reduce the compressor run time during a control event to reduce the demand on the
electrical grid during event periods. Relay(s) inside the device will interrupt the control signal
from the thermostat to the compressor and will only disable the compressor periodically during a
control event. The indoor fan will continue to run during this time. The indoor temperature is
expected to rise a few degrees during the event, depending on the amount of insulation in the
premise.

Water Heater/Pool Pump/Refrigeration

For controlling electric water heaters, pool pumps, or refrigeration, IntelliPEAK DirectLink is
typically installed near the appliance or power source and interrupts the power to the appliance
for control. During control event periods, IntelliPEAK will open the power connection to the
appliance to reduce the demand on the electrical grid. It is expected that the load will be
disabled for the entire duration of the control period.

LED and What Do They Indicate

IntelliPEAK contains up to four1 LED (Light Emitting Diodes) underneath a clear window in
front of the unit. These LEDs show the operation of the IntelliPEAK device as shown below:

LED Indicators

IntelliPEAK DirectLink used in water heater/pool pump/refrigeration contain only one (1) relay

and has three (3) LEDs – Relay2 LED is not present.

Link LED

The Link LED is used to indicate the status of the communication link. When it stays on solid, it
indicates good end-to-end communication with the controlling software system. If any link
along the communication chain is lost, the LED will blink at different patterns as shown below:

Ad-hoc mode – IntelliPEAK is creating its
own Wi-Fi network to allow entry of

1 second on, 3 second off blink

Client mode - Wi-Fi network connected,
waiting for internet connection

3 seconds on, 1 second off blink

Client mode – Wi-Fi/internet network
connected, but not connected to controlling
software

Solid On

Client mode - Cellular/internet/software
connection OK

Test LED

The Test LED is used by the installer during installation. When the device is first powered up,
the Test LED will flash either one or two times to indicate a cold or warm start respectively. The
Test LED can also be manually toggled by the installer to test end-to-end communication with
the software using his test tool. In normal operation, this LED should be off.

Relay LED

The relay LED(s) is used to indicate whether the appliance is prohibited from running during a
control event. It is turned on whenever the appliance (HVAC, water heater, pump or
refrigeration) is being controlled and is prohibited from running. When used with HVAC2, the
compressor is controlled and released periodically. This allows some amount of
cooling/dehumidification as well as air circulation during the control period to minimize
customer discomfort. This LED will turn on during the times when the HVAC is turned off.

2

HVAC may have multiple compressor stages. In these installations, each relay is used to
control each stage of the compressor and both relays will open at the same time to prohibit both
stages of the compressor from running during a control event.
