Utility Load Shedding Mode ACTIVATED (Utility Cycled Unit OFF) – The normally closed set of contacts in the utility load shedding control receiver OPEN.
This removes 24VAC from the coil of the field-provided relay (catalog # 69J79). The relay contacts close (terminal 7 to terminal 2), completing the circuit between terminals R and L on the outdoor control. The 24VAC input to terminal L activates the load shedding mode in the outdoor control, cycling the outdoor unit OFF. The 7-Segment display on the outdoor control displays a load shedding alert code (E600) and an alert appears on the display of the iComfort Wi-Fi® thermostat. The customer receives email notifications when the alert occurs, if the option to receive notifications is selected.
Utility Load Shedding Mode DEACTIVATED (Normal Equipment Operation) – When load shedding is not required, the contacts in the utility load control receiver are closed. This provides 24VAC to the coil of the field provided relay (catalog # 69J79).The relay contacts OPEN (terminal 7 to terminal 2) removing 24VAC from the L terminal on the outdoor control. This deactivates the load shedding mode in the outdoor control. The outdoor unit returns to normal operation and alert code clears once load shedding mode is deactivated.
