Titus Thermal T3SQ-4, IOM - Manual (Page 2)

For system balancing, the springs (A) must be
disconnected from the control disc (B) to allow the
control disc to go to full open. (See Figure 2)
After balancing, reconnect the springs to the control
disc. If the actuator arms are not connected to the
control disc the diffuser will not operate.
Ensure that each control disc spring (A) is attached
to both the control disc (B) and the lever arm (C)
before installing.

Step 2
Adjust room temperature:
Turn the blue ring assembly (D) to the desired
temperature indicated ( 66°F to 74°F)
To adjust the offset differential between heating
and cooling, turn the green tab (E) clockwise to
increase positive temperature offset and
counterclockwise to increase temperature offset in
a negative direction.
Step 5
Installation is completed by lining up the hooks on
the face plaque assembly with the corresponding
slot. The hooks are inserted and the face plate
assembly is rotated clockwise, and lowered so
that each hook is firmly in place. (See Figure 3)
Step 6
Minimum airflow can be adjusted from 30% of
maximum down to fully closed or 0% of maximum
by turning the grey flow adjustment ring (F)
clockwise.
