TEF
PI Controller and Thermostat
Applications
•
Individual PI-control of the temperature in rooms that are heated or cooled with 2-pipe systems or 4-
pipe systems using spring return fan coil valves.
•
Cost efficient control of pressure dependent VAV units.
•
Positioning of an on/off actuator by using the running time of the actuator
•
Controlling the temperature output of a simple air-handling unit with one heating or cooling coil.
•
Radiator or floor heating, cooling ceiling.
General Description
The TEF is a stand-alone electronic temperature controller with one PI control loop. It features 1 PI sequence
and 2 binary sequences. The TEF features 1 NTC temperature sensor input. One additional function is the
manual positioning of a floating actuator.
The TEF features 2 binary outputs (Relays). A detailed parameterization is possible with the use of a simple
configuration routine. The TEF can be configured using the standard operation terminal. No special tools or
software is required.

Selection of actuators and sensors
Temperature Sensors: Use only our approved NTC sensors to achieve maximum accuracy. Recommended is
SDA-Tn10-20 as Duct sensor, SRA-Tn10 as Room sensor and SPA-Tn10-10 as immersion sensor.
Floating Actuators: Any actuators with less than 250 VAC, 100W are acceptable. Actuators with constant
running time are preferred for optimum functionality.
Binary auxiliary devices: E.g. pumps, fans, on/off valves, humidifiers, etc. Do not directly connect devices that
exceed 250 VAC, 100W.

4. Numerical LED display with 2 digits. Indication of current value or setpoint Display The TEF controller features a two digit number display and two dual colors status-LED. Power Failure All the parameters and set points are memorized and will not have to be reentered. The unit will return to the operation mode it was in before the power failure. -
Page 4: Operation
If required it is possible to shift the temperature –3° to +3° in 0.5° K steps. Display in analog mode, 0 = 0-10, 1 = 0-100 V1.3a, 20100504 © Vector Controls GmbH, Switzerland Page 4/8 Subject to alteration... -
Page 5: Switching Frequency
E5: Integral Reset Time Switching frequency The TEF works with two digital outputs to modulate a floating actuator. The position of the actuator is calculated with above described PI algorithm. The controller moves the actuator to the calculated position by either opening or closing the actuator. - Page 6 Pressing UP or DOWN key will display the setpoint. The setpoint is, depending on parameter P10, a value either from 0…10 or 0…100. Since the display has only 2 digits, 100 is indicated as A0.
