Random Start Operation

This feature allows a 2 to 30 second delay before energizing the thermostat outputs after any of these events:

Loss of Power to the thermostat: When power to the thermostat is interrupted and then restored, Random Start will lockout the outputs of the thermostat for a random amount of time. This delay helps to keep multiple thermostats from energizing their outputs at the same time after a power outage.

Changing from an Unoccupied time period to an Occupied

time period: If the thermostat is running in the Program On mode and the start time for an Occupied period forces the thermostat from Unoccupied to Occupied 1, Random Start will lockout all outputs of the thermostat for a random amount of time. This delay helps to keep multiple thermostats from energizing their outputs at the same time each day.

Closure of the Dry Contact to force Occupied 1 time period:

If step #41 (previous page) is programmed for Occupied 1, then Random Start will lockout all outputs of the thermostat for a random amount of time when a Dry Contact closure occurs (depending on step #40). This delay helps to keep multiple thermostats from energizing their outputs each time the Dry 16 Contact is used.

Sensing of a light source by the Light Sensor to force Occupied 1 time period:

If step #42 (page 17.2) is programmed YES for Light Activated operation, Random Start will lockout the outputs of the thermostat for a random amount of time when a light source forces the thermostat into Occupied 1. This delay helps to keep multiple thermostats from energizing their outputs each time the lights are turned on.
