CTE-5201 4 Installation and Operation Guide
Maintenance
Remove dust as necessary from holes in top and
bottom. Clean the display with soft, damp cloth and
mild soap. Each component is designed for depend-
able, long-term reliability, and performance. Careful
installation will also ensure long-term reliability and
performance.

3. After using the Up/Down buttons to change
(Add or Sub) the offset the appropriate value,
press and hold both the MIN and INT buttons
until the display starts flashing and the new
offset is stored in memory.
below 50° F, a safety override will bring the
output up to 2 volts. The output will return to 0
volts when the room temperature reaches 55° F.
• In Deadband Mode (db), the integral action
is disabled, the setpoint reverts to the default
setpoint, and a deadband of ±10° F is established
around the setpoint. As long as the room temper-
ature is within the deadband the output will be
half-way between the MIN and MAX values. For
example, with the factory defaults (setpoint of 70°
F, Min. of 20%, and Max. of 100%) in Deadband
Mode, while the room temperature is between 60
and 80°, the output remains at 60%.
NOTE: Using Deadband Mode would usually keep
the unoccupied room temperature closer to
the default (occupied) setpoint temperature
than the Off Mode.
PROP
The proportional band (Pb) is the temperature band
around the setpoint over which the output will vary
from MIN to MAX due to the proportional action
alone. The proportional band is adjustable from 2 to
6° F (1.1 to 3.3° C).
INT
As long as there is an error between room tempera-
ture and setpoint, the integral action (In) 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.
Calibration (Temperature Offset)
Pressing both MIN and INT buttons simultaneously
enables the option to calibrate the thermostat by
offsetting the internal temperature sensor by up to
±2° F (±1.1° C). To test/calibrate:
1. Carefully position an accurate thermometer or
temperature probe next to the thermostat and
(after sufficient time for the thermometer or
probe to stabilize) compare readings. If there is
an undesirable discrepancy, adjust the tempera-
ture offset value.
NOTE: Body heat can affect the temperature of the
thermostat and/or a thermometer.
2. Momentarily press both MIN and INT buttons
simultaneously.
