This DIP switch allows for a shoulder charge period for the device controlled on relay #1. Five (5) hours after a peak signal is received, relay #1 will close for four (4) hours. The relay will then open again and will remain open until an off-peak or anticipated peak signal is received. If an off-peak or anticipated peak signal is received during the five hour period, the timer will reset.
Off = Shoulder charging disabled
On = Shoulder charging enabled
NOTE: The duration of the delay and the outdoor temperature settings are preset at the factory. If you have an application which requires a change to these settings, please contact the factory.
