VAV T4 RT (4 TRIACS / pressure independent)
VAV CT 24 (Thermostat 2x4)
Description
The DEOS Zoning System provides a simple and efficient demand-
based control of pressure independent and pressure dependent
VAV zones with roof top units (RTU) in light commercial
applications (2 to 20 tons). These products provide a local BACnet
MS/TP communication bus to ensure data exchange of all required
information between the zones and the RTUs, which permits
seamless integration with a third party BMS system.

2. Slide the actuator onto the shaft.
3. Tighten the nuts on the “U” bolt to the shaft with an 8mm
wrench to a torque of 60 in-lb [6.7 Nm].
4. Slide the mounting bracket under the actuator. Ensure free
movement of the slot at the base of the actuator. Place the
bracket pin at mid distance of the slot.
5. Affix the bracket to the ductwork with #8 self-tapping screws.
Do not press the clutch when the actuator is powered.

This menu is accessible through normal operation mode. The Mode Selector jumper (JP1) of the thermostat must be set to the
“RUN” position (Operation Mode). Refer to Wiring on page 4.
1. Press the [*] and [] buttons simultaneously for 5 seconds. The “Enter Password” screen appears.
2. Enter the password within 1 minute by using the arrow keys to increase or decrease the value and the [*] and []buttons to
toggle between the digits. N:\Instructions Production\PDF-1\Actuators\DEOS
a. Password 372 = Temperature Offset Menu
b. Password 637 = Network Settings Menu
c. Password 757 = Airflow Balance Mode
3. If you enter the wrong password, the thermostat displays “Eror” and returns to Operation Mode. The thermostat will return to
normal mode if you navigate through the entire menu and do not make any selection, or if you do not press any key for 5
minutes. The changed values will be saved automatically.
Menu 372 –Temperature Offset
1. Press the [*] and [] buttons simultaneously for 5 seconds.
2. Enter the password 372 within 1.
3. The changed values will be saved automatically.
Compare the displayed temperature reading with a known value from a thermometer. To offset or calibrate the sensor, use the
arrows key to set the desired temperature reading. This is useful for thermostats installed in areas where the temperature read is
slightly different than the room’s actual temperature. For example, a thermostat placed right under the air diffuser. If the thermostat
is set to use an external temperature sensor (EtS), the thermostat displays “OFF”.
