Stand-Alone Operation
Stand-Alone Room Thermostat Occupancy
Programming
The WT-4000 Series Room Thermostats can operate
as stand-alone pneumatic-to-DDC room thermostats
with an independent time clock, and can be
programmed with a Weekday/Weekend occupancy
schedule.
During stand-alone operation, a person icon appears in
the upper-right corner of the LCD (Figure 17). When
the room thermostat is powered up for the first time, the
number 1024 appears on the bottom of the LCD
indicating that the time and date need to be set before
the device can operate according to the occupancy
schedule.
A complete 7-day schedule consists of two
independent components:
Weekday Schedule – Monday through Friday
Weekend Schedule – Saturday through Sunday
Each component is split into two parts to be scheduled
as Occupied or Unoccupied Mode:
Weekday 1
Weekday 2
Weekend 1
Weekend 2
Each part can be configured to Occupied or
Unoccupied Mode independently, to accommodate for
daytime or nighttime shift schedules.
For each Occupied Mode, the following features can be
configured:
Occupied Mode start time
Temperature setpoint range – adjustable ±14F°
(±8.4C°) by the room occupants
For each Unoccupied Mode, the following features can
be configured:
Unoccupied Mode start time
Upper temperature limit
Lower temperature limit – the room thermostat is
off while the room temperature is within these limits
