WT-4000 Series Pneumatic-to-Direct Digital Control (DDC) Room Thermostats Installation Instructions
Description
Occupancy mode requested by the BAS:
1 – occupied; 2 – constrained float (unoccupied); 3 to 6 – reserved; 7 –
shoulder mode (shallow setback, also used in demand response events)
Comfort zone upper range relative to system master setpoint; default 3°F;
maximum comfort zone 14° F
Comfort zone lower range relative to system master setpoint; default 3°F;
maximum comfort zone 14° F
Upper temperature limit in unoccupied setback mode; default 85°F; maximum
value restricted by Protect_Up_L temperature (register 12)
Lower temperature limit in unoccupied setback mode; default 55°F; minimum
value restricted by Protect_Lo_L temperature (register 13)
Maximum temperature allowed in the zone; default 90°F
Minimum temperature allowed in the zone; default 50° F
Override duration with one-minute increments; default 120 minutes; maximum
240 minutes
Comfort zone upper delta during override mode; default 5° F; maximum 14° F
Comfort zone lower delta during override mode; default 5° F; maximum 14° F
Temperature control deadband; default 1° F; maximum 14° F
Upper delta; default 5°F.
In shoulder mode, the device does not call for cool if space temperature is
below setpoint plus upper delta.
Lower delta; default 5°F.
In shoulder mode, device does not call for heat if space temperature is above
setpoint minus lower delta.
Display mode setting:
0 – normal LCD and button functionality; 1 – temperature is not displayed and
buttons are disabled; 2 – normal LCD functionality but buttons are disabled
If set to any other value, everything is displayed as normal and buttons are
enabled; this feature is not supported in stand-alone mode.
High indicates 16 bits of 32 bit time stamp in UTC format (UNIX epoch time).
Low indicates 16 bits of 32 bit time stamp in UTC format (UNIX epoch time).
Space temperature value in °F
The branch line pressure requested by the unit based on temperature
measurement, in PSI.
The actual branch line pressure measured by the pressure sensor, in PSI.
Bit 10 – motion detector shoulder mode triggered by lack of motion
Bit 7 – shoulder mode button pressed
Bit 6 – override mode button pressed
Bit 2 – fan on (if applicable)
Bit 1 – cool on (branch line pressure in cooling zone)
Bit 0 – heat on (branch line pressure in heating zone)
The unit's current mode:
1 – occupied; 2 – constrained float (unoccupied); 3 to 6 – reserved; 7 –
shoulder mode
The master (system) setpoint specified by the energy management application;
default 70°F.
