Temperature sensors: Use Vector Controls NTC sensors to achieve maximum accuracy:SDB-Tn10-20 (duct), SRA-Tn10 (room), SDB-Tn10-20 + AMI-S10 as immersion sensor.

Actuators: Choose modulating actuators with an input signal type of 0-10 V DC or 4-20 mA (Min. and max.signal limitations may be set with parameters.3-pointpoint actuators with constant running time are recommended.

Binary auxiliary devices (e.g. pumps, fans, on/off valves, humidifiers, etc):Do not directly connect devices that exceed specified limits in technical specifications – observe startup current on inductive loads.

Installation

Install the controller on an easy accessible interior wall, approx. 1.5 m above the floor in an area of average temperature.

Avoid direct sunlight or other heat sources, e.g. the area above radiators and heat emitting equipment.

Avoid locations behind doors, outside walls and below or above air discharge grills and diffusers.

Location of mounting is less critical if external temperature sensors are used.

Ensure adequate air circulation to dissipate heat generated during operation.

Observe local regulations.

Do not mount in a wet or condensation prone environments.

Use copper, twisted pair, conductors only. The operating voltage must comply with the requirements for safety extra-low voltage (SELV) as per EN 60 730. Use safety insulating transformers class II with double insulation as per EN 60 742; they must be designed for 100% ON-time. When using several transformers in one system, the connection terminal 1 must be galvanic connected. TCI is designed for operation of AC 24 V safety extra-low voltage and is short-circuit-proof.

Override of secondary set point in cascade control

If cascade control is active, withvariable air volume (VAV) for example,the user can override the primary loop and manually select the set point of the secondary loop-the loop is now changed to constant air volume (CAV). Typically for tuning the VAV system.This feature may be disabled with UP02.

While the secondary loop is displayed change the set point with UP/DOWN. Override Cascade symbol appears.

Press OPTIONto move back to the temperature loop and cancel cascade override.
