Titus Hvac Titus Ii Reset Volume Controller — Pressure-Independent Low-Pressure Damper Control

Designed to deliver precise duct velocity regulation from 0 to 3000 fpm, the Titus II Reset Volume Controller performs reliably at very low system pressures — effective at 0.03” Ps up to 6.0” Ps. Its pressure-independent reset span stays constant even when maximum and minimum cfm settings are changed. The factory span is set to 5 psi and can be adjusted between 3 to 10 psi to suit different thermostats. The controller’s reset start point is user-adjustable from 3 to 13 psi (factory setting: 8 psi), allowing compatibility with accessories such as reheat coils. A thermostat switch lets you switch the action from direct-acting to reverse-acting without additional calibration, and no extra relays are required — a benefit for fast retrofit jobs. Likewise, a damper switch changes operation between normally open and normally closed without recalibration or added relays. All set-up and tuning are performed using the hex-shanked adjustment knob stored in the face of the Titus II controller. It operates on a control air pressure of 15 to 25 psi and consumes no more than 1.2 scfh of control air. Product Dimensions : 6.7 x 4.4 x 3.4 inches; 5.61 Pounds. Built from durable materials for long service life, this controller is engineered to withstand heavy use and harsh conditions. Installation is straightforward for both DIYers and professional technicians, and the unit has been thoroughly tested to meet industry standards for reliable temperature controls.
