VECTOR TRI2 Controller
TRI2 operates independently of the air conditioning plant to provide temperature-based zoning control for
one zone. Features include:
• Integrated sensor or optional remote room sensor (not included)
Select the integrated sensor or the optional remote room sensor
• 24 VAC power supply
Offers substantial savings in installation costs compared to 240VAC systems
• Digital Display
Tell at a glance if the zone is open for cooling or heating.
• Quick & Easy Wiring
• BMS Integration
• Adjustable Minimum Ventilation setting
Restricts the damper from fully closing to maintain a minimum airflow.
Control Usage
TRI2 is a variable air volume zone controller suitable for use with any centralised conditioning source (e.g.
reverse cycle systems) Zoning kits comprise of one of each of the following components.
• TRI2 Controller (V-TRI2) - integrated sensor and supply air sensor
• Motorised Damper (MDB-XXX-IC) XXX = the size of the damper.
• Transformer (TFORM-24)
Touchscreen Touchpad
The TRI2 touchscreen controller compares the temperature of the air being supplied with the temperature
of the zone and modulates the damper in a direction that will benefit the zone. Zone motors connect to
and receive power from the touchpad via the Innocab cable system. Terminal connections are provided for
the 24VAC power supply, the supply air sensor, and optional external room sensor. TRI2 is equipped with
minimum ventilation calibration which adjusts a virtual stopper on the motor so that the motor is held
open a set percentage only when the zone is ON. Turning the zone OFF will override minimum ventilation
and fully close the motor.
