Model CTE-5201W16 Thermostat:
Model CTE-5201-16 (LCD analog thermostat) (Figure 2) - single
output with limits, PI function is designed to be used with the
CEE-5201 Fan Coil Unit controller (Figure 1). Model CTE-5201-16
Thermostat comes with the following factory default settings:
Set Point (Default): 70°F
MAX: 100%
MIN: 20%
F/C Mode: Degrees F
UNOCC Mode: OFF
PROP: 4ºF
INT: 30 Minutes
To change any one of these values, except the F/C Mode, first
push the button to display the value to be changed. Use the Up /
Down buttons to change the value. Then hold down the
corresponding button for approximately 10 seconds until the display
begins to flash. The new value has now been written into memory.
To change to degrees C mode simply press and hold the F/C
button down for 10 seconds until the display begins to flash. To
change back to degrees F repeat the procedure.
Set Point (Normal)
The set point range is 60 – 85°F (15.6 – 29.4°C). To change the
set point, push the SET POINT button to display the current value.
Use the Up / Down buttons to change the value. The display will
time out and revert back to displaying the room temperature and
the thermostat will control to the new set point.
Set Point (Default)
If power is lost, when the unit is powered back up, the set point will
revert to the default value of 70°F (21.1 C). This default value can
be changed to any value in the set point range. This default set
point is also used in the dead band unoccupied mode.
MAX
This is the maximum value that the output can attain. It is
adjustable up to 100% (10 volts) and down to the MIN setting.
MIN
This is the min. value that the output can attain. It is adjustable
down to 0% (0 volts) and up to whatever the MAX is set for.
F/C Mode
The F/C button toggles the display between °F and °C. Room
temperature, set point, proportional band, dead band, and offset
will be displayed in the desired units.
UNOCC
Momentarily pressing this button will put the unit into the
unoccupied mode. It will stay in this mode until either the Set Point
or Up / Down buttons are pushed. There are two unoccupied
modes, OFF or DEADBAND.
OFF UNOCC Mode
The output voltage is forced to 0 volts (0%). A safety override will
bring the output up to 2 volts placing the unit in heating if the room
temperature falls below 50°F. The output will return to 0 volts
when the room temperature reaches 55°F.
DEADBAND UNOCC Mode
In this mode the set point is set to 70°F, the integral action is
disabled, and a dead band of +/- 10°F is set around the set point.
As long as the room temperature is within the dead band the fan
will run at MIN conditions.
PROP
The proportional band is the temperature band around the set
point over which the output will vary from MIN to MAX due to the
proportional action alone. The proportional band is adjustable from
2 – 6°F (1.1 – 3.3°C).
INT
As long as there is a difference between room temperature and
set point, the integral action will cause the output to integrate up
or down. The integral time is the time it takes the integral action to
repeat the effect of the proportional action. The integral time is
adjustable from 15 to 30 minutes. Setting the integral time to 0 will
disable the integral action.
Temperature Offset
By pressing both MIN and INT together it is possible to offset the
internal temperature sensor by +/- 2°F (+/- 1.1°C). After using the
Up / Down buttons to change the offset both the MIN and INT
buttons must be held down together for 10 seconds until the
display begins to flash in order to write the new offset into memory.
