Random Start OperationRandom Start Operation
This feature allows a 2 to 30 second delay before energizing
the thermostat outputs after any of these events:
16
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
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.
